Negligence in Personal Injury Claims

Negligence in personal injury law is a legal cause of action that allows an injured person to recover compensation from another party whose careless conduct caused the injury. Negligence is a category of tort and is by far the most common cause of action pursued in personal injury claims in Queensland. A negligence claim succeeds only where all four elements are established on the balance of probabilities by the claimant, with the four elements being duty of care, breach of duty, causation, and damage. Most negligence claims that fail do so on breach or causation rather than on duty, because the established duty categories cover the relationships in most personal injury contexts.

The legal framework for negligence in Queensland combines common law principles developed since Donoghue v Stevenson [1932] AC 562 with statutory modifications under the Civil Liability Act 2003 (Qld) and the Workers' Compensation and Rehabilitation Act 2003 (Qld). The Civil Liability Act codifies the test for breach in section 9, the test for causation in section 11, and the standard of care for professionals in section 22, while the Workers' Compensation and Rehabilitation Act applies parallel tests in sections 305B and 305D for workplace common law claims. Negligence applies across the main personal injury claim types, including motor vehicle accidents under the Motor Accident Insurance Act 1994 (Qld), workplace injuries, public liability matters, medical negligence claims, and product liability claims, with the four-element framework adapting to the specific relationships and circumstances in each context.

The negligence framework is modified in practice by contributory negligence, which reduces the compensation a successful claimant receives by a percentage reflecting the claimant's share of responsibility, and by full defences including inherent risk (s 16), obvious risk (ss 13-15), voluntary assumption of risk, dangerous recreational activity exclusions, and statutory good Samaritan provisions. Where multiple parties are negligent in causing the same harm, Queensland law allocates responsibility through apportionment between concurrent tortfeasors under the Law Reform Act 1995 (Qld) and vicarious liability of one party for the negligent conduct of another, with employers and institutions the most common defendants held vicariously liable. Proving negligence requires evidence-gathering across all four elements through pre-court procedures, expert reports, and the compulsory conference settlement process, with fewer than 1% of personal injury claims in Queensland proceeding to trial.

What is negligence in personal injury law?

Negligence in personal injury law is a legal cause of action that allows an injured person to recover compensation from another party whose careless conduct caused the injury. Negligence is a category of tort, meaning a civil wrong recognised by the courts as giving rise to a right to compensation. The negligence cause of action is by far the most common basis for personal injury claims in Queensland, and rests on the principle that every person owes a duty to take reasonable care to avoid foreseeable harm to others. Where that duty is breached and causes compensable injury, the law of negligence provides a remedy in damages.

The negligence framework is a creation of common law (judge-made law developed through court decisions over centuries), modified in Queensland by statute. The foundational principles of modern negligence trace to Donoghue v Stevenson [1932] AC 562, the House of Lords decision that established the "neighbour principle" requiring reasonable care toward those who could foreseeably be affected by one's conduct. The neighbour principle remains the conceptual foundation of modern negligence law, with Queensland's statutory framework, particularly the Civil Liability Act 2003 (Qld), codifying and modifying the common law of negligence in significant ways. Despite the statutory overlay, the negligence cause of action retains the four-element structure that has applied since the early twentieth century. The four elements of negligence are duty of care, breach of duty, causation, and damage.

Negligence is distinct from intentional torts such as battery, assault, and false imprisonment, which require proof of deliberate wrongful conduct rather than carelessness. A driver who runs a red light while distracted has acted negligently, while a driver who deliberately rams another vehicle has committed an intentional tort. Personal injury law primarily addresses negligence because the vast majority of injuries arise from carelessness rather than deliberate conduct. Negligence in the personal injury context is also distinct from no-fault compensation pathways such as Queensland workers' compensation statutory benefits and the National Injury Insurance Scheme Queensland (NIISQ), which provide compensation regardless of whether anyone was at fault.

The practical importance of negligence in personal injury claims is that the negligence framework determines whether compensation can be recovered at all in fault-based schemes. A claimant who suffered serious injury but cannot establish negligence against another party generally cannot recover damages under the main personal injury claim types such as Compulsory Third Party (CTP) claims, public liability claims, and workers' compensation common law claims. Establishing negligence is the threshold requirement in most personal injury claims in Queensland, and a claim succeeds only where each of the four elements can be proven on the balance of probabilities (the civil standard of proof, requiring the claimant to establish each element as more probable than not).

What are the elements of negligence?

The elements of negligence in Queensland personal injury law are the four legal components a claimant must prove to succeed in a negligence action. These are duty of care, breach of duty, causation, and damage. Each element operates as an independent requirement, and a failure to establish any one of the four elements defeats the negligence claim regardless of how strong the other elements may be. The four-element structure originates in the common law and is now reflected in the Civil Liability Act 2003 (Qld), which codifies the tests for breach (s 9) and causation (s 11) and modifies certain aspects of the common law approach.

Some legal commentary describes negligence as having five elements, separating causation into "factual causation" and "legal causation" (also called proximate cause or scope of liability) as two distinct requirements. Queensland law treats causation as a single element with two components rather than two separate elements, consistent with the structure of section 11 of the Civil Liability Act 2003 (Qld), which sets out factual causation and scope of liability as the two limbs of a single causation test. The four-element framework is the standard articulation in Queensland courts and academic writing, although readers should be aware that the five-element framing appears in some Australian and overseas sources.

The burden of proof for each element rests on the claimant, who must establish each element on the balance of probabilities. The defendant has no obligation to disprove the elements, with the claim failing where the claimant cannot meet the evidentiary threshold on any one of the four. In practice, most negligence claims that fail do so on breach or causation rather than on duty, because the established duty categories cover most personal injury claim types and the existence of a duty is rarely contested. 

The four elements of negligence are further explained in detail below. 

1. Duty of care

Duty of care in negligence is a legal obligation requiring a person to take reasonable care to avoid acts or omissions that could foreseeably cause harm to another. The duty arises from the relationship between the parties and the circumstances in which the conduct occurs, and is the threshold element of negligence. Where no duty of care is owed, no negligence claim can succeed regardless of how careless the defendant's conduct may have been.

Some categories of duty of care are well established in Queensland law and apply automatically once the relevant relationship exists. The established categories of duty of care commonly recognised in Queensland personal injury claims are set out below.

• Driver to other road users. A driver of a motor vehicle owes a duty of care to all other road users, including other drivers, passengers, pedestrians, and cyclists.
• Employer to employees. An employer owes a non-delegable duty of care to employees to provide a safe system of work, safe equipment, and competent fellow workers.
• Occupier to entrants. An occupier of premises owes a duty of care to entrants on those premises, with the standard varying according to the entrant's purpose and the occupier's relationship to them.
• Medical practitioner to patients. A medical practitioner owes a duty of care to patients in respect of diagnosis, treatment, and the provision of information about risks.
• Manufacturer to consumers. A manufacturer owes a duty of care to ultimate consumers of products placed into commerce.

These established categories cover the majority of personal injury claims and rarely raise contested duty questions.

In novel situations where no established category applies, duty of care is determined by reference to the principles set down in Donoghue v Stevenson and developed by subsequent High Court of Australia decisions, including Sullivan v Moody [2001] HCA 59. The modern test focuses on whether the defendant could reasonably have foreseen that conduct of the type in question would cause harm to a person in the claimant's position, and whether the relationship between the parties is sufficiently proximate to give rise to a legal obligation. The High Court has moved away from any single overarching test for duty of care in favour of a multi-factorial analysis that considers foreseeability, vulnerability of the claimant, the defendant's control over the risk, and the broader policy implications of recognising a duty in the relevant context.

The Civil Liability Act 2003 (Qld) does not codify a general test for duty of care but does modify the common law in specific contexts. The Act modifies the common law duty of care in the following three ways.

• Dangerous recreational activities (Part 1 Division 4). The Act limits the duty of care owed in connection with dangerous recreational activities, including by limiting liability for harm caused by the materialisation of an obvious risk.
• Professionals practising in their area of expertise (s 22). The Act modifies the duty owed by professionals through the peer professional opinion test, which provides that a professional does not breach a duty of care if they acted in a manner widely accepted by peer professional opinion as competent professional practice.
• People engaged in certain criminal conduct (s 45). The Act places restrictions on duties owed to claimants whose injury arose in the course of their own criminal conduct, limiting the circumstances in which damages can be recovered.

Contested duty of care questions in Queensland personal injury claims most often arise where established categories interact with novel circumstances such as employers' duties to independent contractors, occupiers' duties to trespassers, the boundaries of professional duties owed by allied health practitioners, and duties owed by public authorities exercising statutory functions. The scope of duty of care in personal injury claims continues to develop through High Court and Queensland Court of Appeal decisions, with the modern approach favouring multi-factorial analysis over any single overarching test.

2. Breach of duty

Breach of duty in negligence occurs when a person whose conduct is governed by a duty of care fails to meet the standard of care a reasonable person would exercise in the same circumstances. The breach element asks whether the defendant's specific conduct fell below the legal standard, and is the second element a claimant must establish to succeed in a negligence action. Where the duty of care exists but the defendant's conduct met the required standard, no breach has occurred and the claim fails at this stage.

The standard of care in Queensland negligence is set by reference to what a reasonable person would have done in the defendant's position, taking into account the circumstances in which the conduct occurred. The reasonable person is a legal construct rather than any specific individual, and represents the community's expectation of careful conduct in the relevant context. The standard is objective, meaning the defendant's personal characteristics, inexperience, or genuine but mistaken belief that they were acting carefully are generally irrelevant. A learner driver is held to the same standard as a competent driver. A junior medical practitioner is held to the same standard as a competent practitioner in the same role.

Section 9 of the Civil Liability Act 2003 (Qld) codifies the test for breach of duty in Queensland and replaces the common law approach in most personal injury contexts. Under section 9, a person breaches a duty of care only where the following three requirements are all satisfied.

• Foreseeability of the risk. The risk of harm must have been foreseeable at the time of the conduct, meaning a person in the defendant's position knew or ought reasonably to have known of the risk.
• Not-insignificant risk. The risk of harm must not have been insignificant, meaning the risk must rise above the trivial or far-fetched.
• A reasonable response was not taken. A reasonable person in the defendant's position would have taken the precautions that the defendant failed to take.

The third requirement involves balancing four factors known as the calculus of negligence. The calculus of negligence is the analytical framework Queensland courts apply to determine whether a reasonable person in the defendant's position would have taken precautions against the foreseeable risk, by weighing the costs of taking precautions against the likelihood and severity of the harm those precautions would have prevented. The framework originated in Wyong Shire Council v Shirt (1980) 146 CLR 40 and is now reflected in section 9(2) of the Civil Liability Act 2003 (Qld). 

The four factors of the calculus of negligence are set out below.

• Probability of harm. The likelihood that harm would occur if precautions were not taken.
• Seriousness of harm. The likely magnitude of harm if it does occur, including the severity of injury and the number of people who could be affected.
• Burden of precautions. The cost, difficulty, and inconvenience of taking the precautions that would have avoided the harm.
• Social utility of the activity. The value to society of the activity that creates the risk, such as emergency response work or essential public services.

Professionals such as medical practitioners, lawyers, engineers, and accountants are held to a different standard under section 22 of the Civil Liability Act 2003 (Qld), known as the peer professional opinion test. A professional does not breach a duty of care if they acted in a manner widely accepted by peer professional opinion as competent professional practice, even if a court might consider the practice flawed. The peer professional opinion test does not apply where the conduct in question was so unreasonable that no reasonable professional could have considered it competent, or where the breach concerns a duty to warn of a material risk associated with treatment. The professional standard interacts with established medical and other professional duties to set the threshold against which expert evidence on standard of care is measured in negligence claims.

The factual question of whether breach occurred is generally determined by evidence of what the defendant in fact did, what a reasonable person would have done, and how the defendant's conduct compared. Witness evidence, documentary evidence, and where appropriate expert evidence on standard of care are all relevant. In cases involving professionals, expert evidence from another professional in the same field is essential to establish what competent practice looks like and where the defendant's conduct departed from it. The breach question is decided on the balance of probabilities, with the burden resting on the claimant to prove that the standard was breached.

3. Causation

Causation in negligence is the legal requirement that the defendant's breach of duty caused the harm the claimant is seeking compensation for. Causation is the third element a claimant must establish, and operates as the link between the defendant's negligent conduct and the claimant's compensable injury. Where the breach occurred but did not cause the harm, the negligence claim fails on causation regardless of how clear the duty and breach elements may be.

Section 11 of the Civil Liability Act 2003 (Qld) sets out the test for causation in Queensland and replaces the common law approach in most personal injury contexts. The section 11 test has two limbs that must both be satisfied for causation to be established. The two limbs of the causation test are set out below.

• Factual causation. The breach of duty must be a necessary condition of the occurrence of the harm. The standard test is the "but for" test, which asks whether the harm would have occurred but for the defendant's negligent conduct. Where the harm would have occurred regardless of the defendant's conduct, factual causation is not established.
• Scope of liability. It must be appropriate for the scope of the negligent person's liability to extend to the harm caused. The scope of liability limb (sometimes called legal causation or remoteness) addresses whether the defendant should be held responsible for the particular harm in question, taking into account whether the harm was a foreseeable consequence of the breach and whether holding the defendant liable accords with established legal principles.

The "but for" test requires the claimant to establish that the harm would not have occurred if the defendant had acted with reasonable care. Where the same harm would have occurred even with reasonable care, the breach is not a necessary condition of the harm and factual causation fails. A patient who suffered a poor outcome from negligent surgery cannot establish causation where the same outcome would have occurred from competent surgery, because the negligence was not a necessary condition of the harm.

In situations where multiple causes contributed to the harm, the "but for" test can be modified. Section 11(2) of the Civil Liability Act 2003 (Qld) provides that in exceptional cases, factual causation may be established even where the "but for" test cannot be satisfied, where the case for liability is otherwise compelling and the breach materially contributed to the risk of harm. The material contribution principle is most often applied in cases involving multiple potential causes of injury or where scientific or evidentiary uncertainty makes strict "but for" proof impossible.

Pre-existing conditions are a common complication in personal injury causation. The "egg-shell skull" principle (also called the "thin skull" rule) provides that a defendant takes the claimant as they find them. Where the defendant's negligence aggravates a pre-existing condition or causes greater harm than would have occurred to a person without the pre-existing condition, the defendant remains liable for the full extent of the harm caused. The principle prevents defendants from avoiding liability by pointing to the claimant's vulnerability. The application of the egg-shell skull principle interacts with the requirement for medical evidence establishing the pre-existing condition, the negligence-related harm, and the relationship between the two, which is one of the most evidentially complex aspects of negligence claims.

Causation is a frequent battleground in personal injury claims, particularly in medical negligence matters where the defendant's conduct must be separated from the underlying medical condition that brought the claimant to treatment in the first place. The claimant carries the burden of proving causation on the balance of probabilities, with the medico-legal evidence typically central to whether causation can be established.

4. Damage

Damage in negligence is the actual harm or loss the claimant suffered as a result of the defendant's breach of duty. Damage is the fourth and final element of negligence, and operates as the requirement that the negligent conduct produced compensable consequences. Where a defendant has breached a duty of care without causing any harm, no actionable negligence has occurred, because damage is an essential component of the cause of action rather than an optional add-on.

Compensable damage in personal injury negligence covers physical injuries, psychiatric injuries, and the financial losses that flow from those injuries. Physical injuries include any bodily harm caused by the negligent conduct, ranging from minor soft tissue injuries through to catastrophic spinal cord and traumatic brain injuries. Psychiatric injuries cover recognised psychiatric conditions diagnosed by a qualified mental health professional, including post-traumatic stress disorder, major depressive disorder, anxiety disorders, and adjustment disorders. The threshold of a recognised psychiatric injury is important, because mere distress, grief, or upset that does not meet that threshold is generally not compensable in negligence. The financial losses that flow from physical and psychiatric injuries include lost earnings, medical treatment costs, rehabilitation expenses, and care and assistance costs.

Pure economic loss is financial loss that is not connected to physical or psychiatric injury, and is generally not recoverable in personal injury negligence claims. The negligence cause of action in personal injury contexts requires harm to the person, with the financial losses being consequential to that harm rather than the harm itself. A claimant who suffers no physical or psychiatric injury but loses income or business opportunity through another party's careless conduct is therefore unlikely to recover under personal injury negligence, although other causes of action such as negligent misstatement or breach of contract may apply in commercial contexts.

Remoteness of damage is a separate requirement within the damage element of negligence. The remoteness test asks whether the type of harm suffered was a reasonably foreseeable consequence of the breach, rather than whether the precise extent or manner of the harm could have been predicted. The "egg-shell skull" principle interacts with remoteness in that, once the type of harm is foreseeable, the defendant is liable for the full extent of the harm even if the claimant's particular vulnerability made the consequences worse than would have occurred to an average person.

Damage in a negligence claim is quantified through the recognised heads of damage, which are the categories of compensation a claimant can recover. The principal heads of damage in Queensland personal injury negligence are general damages for pain and suffering and loss of amenities of life, past economic loss, future economic loss, past and future treatment costs, past and future care costs, and loss of superannuation. General damages are calculated using the Injury Scale Value (ISV) under the Civil Liability Regulation 2025 (Qld), with the maximum ISV of 100 corresponding to general damages of $484,100 for the 2025-26 financial year. Future economic loss is calculated by projecting the claimant's likely earnings over their remaining working life and applying a 5% statutory discount rate to convert future losses to present-day value. The interaction between the types of compensation in personal injury claims and the negligence framework is that each head of damage requires its own evidentiary basis tied to the elements proven in the negligence analysis, particularly the medical evidence on permanent impairment that flows from the causation element.

What is the legal framework for negligence in Queensland?

The legal framework for negligence in Queensland is a combination of common law principles developed by the courts and statutory modifications introduced through the Civil Liability Act 2003 (Qld) and the Workers' Compensation and Rehabilitation Act 2003 (Qld). The common law continues to define the underlying concepts of duty, breach, causation, and damage, while the statutory framework codifies specific tests and modifies certain aspects of liability across most personal injury contexts.

The Civil Liability Act 2003 (Qld), commonly abbreviated as the CLA, is the principal statute governing the law of negligence in Queensland personal injury claims. The CLA codifies the test for breach of duty (s 9), the test for causation (s 11), the standard of care for professionals (s 22), and a range of defences and immunities. The CLA also contains specific provisions on contributory negligence (Part 1 Division 5), recreational activities (Part 1 Division 4), proportionate liability (Part 2), and damages (Chapter 3). The CLA does not replace the common law of negligence in its entirety, but operates as a layered modification under which common law principles continue to apply except where the statute expressly displaces or modifies them.

Section 5 of the Civil Liability Act 2003 (Qld) sets out the categories of personal injury claim to which the CLA does not apply. The categories excluded from the CLA framework are set out below.

• Workplace injury claims governed by the Workers' Compensation and Rehabilitation Act 2003 (Qld). Common law claims arising from workplace injuries operate under the negligence provisions of the WCRA rather than the CLA, with sections 305B and 305D providing parallel but slightly different tests for breach and causation.
• Dust-related conditions. Claims arising from asbestos, silicosis, mesothelioma, and other dust-related conditions are excluded from the CLA, recognising the long latency periods and specific causation difficulties in these matters.
• Tobacco-related claims. Claims arising from injury caused by smoking and tobacco use are excluded from the CLA framework.
• Intentional acts intended to cause injury. Claims arising from acts done with intent to cause injury fall outside the CLA, which is concerned with the law of negligence rather than intentional torts.
• Claims arising from sexual abuse. Claims arising from unlawful sexual assault, abuse, or misconduct are excluded from the CLA, with separate frameworks under the Limitation of Actions Act 1974 (Qld) and other legislation governing those claims.

Workplace injury claims are governed by the Workers' Compensation and Rehabilitation Act 2003 (Qld), commonly abbreviated as the WCRA, which contains its own statutory framework for negligence in the employer-employee context. Section 305B of the WCRA codifies the test for breach of duty in employer negligence claims, and section 305D codifies the test for causation. The WCRA tests largely mirror the CLA tests but contain specific modifications relevant to the workplace context, including the recognition of the employer's non-delegable duty and the interaction between the common law claim and the statutory benefits already received by the worker.

The interaction between the common law and the statutory framework affects how negligence claims are pleaded, proved, and defended. A claim under the CLA must comply with the statutory tests for breach and causation rather than relying on the common law tests directly. A claim under the WCRA must address the statutory tests in sections 305B and 305D and the specific provisions on common law thresholds. The general limitation period for commencing a negligence action in Queensland is three years from the date the cause of action accrued, set under the Limitation of Actions Act 1974 (Qld), with each compensation scheme imposing earlier procedural notice deadlines that operate in parallel. The interaction between the three-year limitation period and the scheme-specific deadlines is the most common procedural trap in negligence claims, because time limits for personal injury claims in Queensland frequently extinguish the right to claim before the claimant realises the limitation period has begun running, unless extension or late-notice provisions are successfully invoked.

When does negligence apply in personal injury claims?

Negligence applies in personal injury claims wherever a person has suffered physical or psychiatric injury caused by another party's failure to take reasonable care, and the relationship between the parties is one in which a duty of care is owed. Negligence is the legal foundation of most fault-based personal injury claims in Queensland, and the practical contexts in which it applies map closely onto the main categories of personal injury claim recognised in Queensland law.

Motor vehicle accident claims rely on negligence to establish that the at-fault driver's conduct fell below the standard of a reasonable driver in the same circumstances. Every driver on Queensland roads owes a duty of care to other road users, and a breach of that duty through speeding, distracted driving, failing to keep a proper lookout, or breaching a road rule is the typical basis on which negligence is established in a Compulsory Third Party (CTP) claim. The procedural framework under the Motor Accident Insurance Act 1994 (Qld) channels the claim through the CTP scheme, but the underlying liability question remains a negligence analysis.

Workplace injury claims at common law depend on the employer's non-delegable duty of care to provide a safe system of work, safe equipment, and competent fellow workers. An employer who failed to identify and address a foreseeable workplace risk has typically breached the duty of care, and the worker's common law damages claim under the Workers' Compensation and Rehabilitation Act 2003 (Qld) requires negligence to be established on the s 305B breach test and the s 305D causation test. Statutory workers' compensation benefits operate independently of negligence, but the common law damages stream that produces the higher compensation requires the full negligence framework to be satisfied.

Public liability claims involve injuries that occurred outside the road and workplace contexts and rely on the occupier's duty of care to entrants on premises. A shopping centre, restaurant, sporting venue, or rental property operator who failed to identify and address a foreseeable hazard such as a wet floor, damaged surface, or unsafe equipment has typically breached the duty owed to the entrant. The negligence analysis in public liability claims is more frequently contested than in CTP claims, because liability often turns on what a reasonable occupier would have done in the specific circumstances rather than on a clear breach of road rules.

Medical negligence claims involve harm caused by substandard medical treatment and apply the negligence framework to the practitioner-patient relationship. The medical practitioner's duty of care covers diagnosis, treatment, and the provision of information about risks, with the standard assessed by reference to the peer professional opinion test under section 22 of the Civil Liability Act 2003 (Qld). The causation analysis in medical negligence is conceptually harder than in any other personal injury context, because the harm caused by the negligent treatment must be separated from the harm that would have occurred from the underlying medical condition anyway.

Negligence also applies in less common personal injury contexts, including product liability claims (where a manufacturer has failed to take reasonable care to design, manufacture, or warn about a product), school and educational settings (where a school has failed to take reasonable care for the safety of students), and recreational and sporting contexts (where an organiser has failed to take reasonable care for the safety of participants). Each context applies the same four-element negligence framework, with the duty, breach, causation, and damage analysis tailored to the specific facts and the relationship between the parties.

What is contributory negligence?

Contributory negligence is a partial defence in negligence under which the compensation a successful claimant receives is reduced to reflect the extent to which the claimant's own conduct contributed to the harm. Contributory negligence does not defeat a negligence claim outright in most circumstances, with the consequence instead being a percentage reduction in the damages awarded that reflects the claimant's share of responsibility.

The legal framework for contributory negligence in Queensland is set out in section 10 of the Law Reform Act 1995 (Qld), which allows the court to reduce damages by an amount it considers fair and equitable having regard to the claimant's share of responsibility for the harm. Sections 23 and 24 of the Civil Liability Act 2003 (Qld) set the standard of care for assessing contributory negligence and confirm that contributory negligence can defeat a claim entirely in Queensland where the claimant is found 100% responsible for the harm.

The standard of care for contributory negligence is the same as the standard for primary negligence. A claimant is contributorily negligent where the claimant's conduct fell below the standard of a reasonable person in the same circumstances, and the claimant's failure to take reasonable care contributed to the accident or to the severity of the injuries. The onus of proving contributory negligence rests on the defendant, who must establish on the balance of probabilities both that the claimant breached the standard and that the breach materially contributed to the harm.

Common examples of contributory negligence in personal injury claims include not wearing a seatbelt in motor vehicle accidents, failing to follow safety procedures in workplace injuries, ignoring warning signs in public liability matters, and failing to follow medical advice in medical negligence claims. The Civil Liability Act 2003 (Qld) imposes statutory presumptions of contributory negligence in specific situations, including a minimum 25% reduction for intoxicated drivers under section 47 and a minimum 25% reduction for passengers travelling with intoxicated drivers under section 48. The minimum reduction for intoxicated drivers increases to 50% where the driver's blood alcohol concentration was 0.15 or above. Outside the statutory presumptions, percentage reductions for contributory negligence in Queensland personal injury claims typically range from 10% for minor lapses such as momentary inattention, through 25% to 40% for speeding or failing to keep a proper lookout, and through to 60% or higher for serious recklessness, with the court considering the relative seriousness of each party's conduct and the causal potency of each party's actions in apportioning responsibility.

What defences exist to a negligence claim?

The defences to a negligence claim in Queensland are the legal grounds on which a defendant can avoid or reduce liability even where the four elements of negligence have been established by the claimant. The defences operate at different stages of the analysis, with some defences denying that the duty extended to the harm in question, others denying that the risk was one a reasonable defendant should have addressed, and others reducing the damages awarded rather than defeating liability outright.

The principal defences to a negligence claim in Queensland are set out below.

• Inherent risk (s 16 Civil Liability Act 2003 (Qld)). A defendant is not liable for harm suffered as a result of the materialisation of an inherent risk, which is a risk that cannot be avoided by the exercise of reasonable care and skill. The defence applies where the risk was inherent in the activity itself rather than created or increased by the defendant's conduct, and is most often invoked in claims involving medical procedures, sporting activities, and naturally hazardous environments.
• Obvious risk (ss 13-15 Civil Liability Act 2003 (Qld)). A defendant has no duty to warn of an obvious risk, defined as a risk that would be obvious to a reasonable person in the claimant's position. The legislation creates a presumption that the claimant was aware of an obvious risk unless the claimant proves otherwise, with the result that voluntarily proceeding in the face of an obvious risk substantially weakens the claim.
• Voluntary assumption of risk (volenti non fit injuria). A defendant escapes liability where the claimant freely and voluntarily accepted the specific risk of harm with full knowledge of its nature and extent. The defence is narrowly applied at common law and requires more than mere awareness of a risk, with the claimant needing to have understood the precise nature of the risk and to have agreed to bear the legal consequences of its materialisation.
• Dangerous recreational activities (Part 1 Divisionil Liability Act 2003 (Qld)). A defendant is not liable for harm suffered by the claimant as a result of the materialisation of an obvious risk of a dangerous recreational activity. The provisions exclude liability for activities that involve a significant risk of physical harm, including activities such as skydiving, rock climbing, white-water rafting, and many high-risk sports.
• Illegality (ex turpi causa). A claim arising from the claimant's own criminal or grossly immoral conduct may be defeated or reduced under section 45 of the Civil Liability Act 2003 (Qld) and at common law. The defence prevents claimants from recovering for harm sustained while engaged in serious unlawful conduct, recognising that the courts should not assist a person to profit from their own wrongdoing.
• Statutory authority and good Samaritan provisions. Public authorities exercising statutory functions may have limited liability under Part 3 of the Civil Liability Act 2003 (Qld), and persons acting in good faith to provide emergency assistance are protected by the good Samaritan provisions in section 26. The defences recognise the public interest in protecting authorities and emergency responders from liability for reasonable conduct in difficult circumstances.

Contributory negligence is sometimes described as a defence, but operates differently from the defences set out above. A successful defence such as inherent risk or voluntary assumption of risk defeats the negligence claim entirely, with no compensation recoverable. Contributory negligence reduces the compensation awarded by a percentage reflecting the claimant's share of responsibility, with the underlying claim still succeeding in a reduced form.

What if more than one party is negligent?

Where more than one party is negligent in causing the same harm, the law of negligence applies two distinct mechanisms to allocate responsibility between the negligent parties. The first mechanism is apportionment between concurrent tortfeasors who each contributed to the harm through their own negligent conduct. The second mechanism is vicarious liability under which one party is held legally responsible for the negligent conduct of another. 

The two mechanisms operate independently but can apply concurrently in the same claim, with the practical effect that a claimant injured by the negligence of multiple parties can recover compensation against all parties whose conduct contributed to the harm.

Personal injury claims in Queensland frequently involve more than one negligent party. A motor vehicle accident may involve negligence by both an at-fault driver and a road authority that failed to address a known hazard. A workplace injury may involve negligence by both the employer and a third party such as a contractor or equipment manufacturer. A medical negligence claim may involve negligence by both the treating practitioner and the hospital that failed to provide adequate systems or supervision. The two H3s below address how the law allocates liability where multiple parties have contributed to the harm.

How is liability apportioned between concurrent tortfeasors?

Liability is apportioned between concurrent tortfeasors by determining the percentage of responsibility each negligent party bears for the harm and allocating the damages accordingly. Concurrent tortfeasors are two or more parties whose negligent conduct independently contributed to the same harm, and the apportionment process determines what share of the total compensation each defendant must pay.

The general rule at common law is that concurrent tortfeasors are jointly and severally liable, meaning the claimant can recover the full amount of damages from any one defendant, with that defendant then entitled to seek contribution from the others according to their respective shares of responsibility. Joint and several liability protects the claimant from the risk of a defendant being unable to pay, because the claimant can pursue the most solvent defendant for the full amount and leave the inter-defendant apportionment to be sorted out separately. The defendant who has paid more than their share can recover contribution from the other defendants under the Law Reform Act 1995 (Qld).

Part 2 of the Civil Liability Act 2003 (Qld) modifies the joint and several liability rule for certain types of claim through the proportionate liability regime. Under proportionate liability, each defendant is liable only for the share of damages that reflects their own responsibility, with the claimant bearing the risk that some defendants may be unable to pay their share. The proportionate liability regime applies to claims for economic loss and property damage in specific contexts, but personal injury claims in Queensland generally remain subject to the joint and several liability rule.

The percentage of responsibility allocated to each concurrent tortfeasor is determined by reference to the relative seriousness of each party's breach and the causal potency of each party's conduct in producing the harm. The court considers what each party did, what each party should have done, and how directly each party's conduct contributed to the injury. The allocation is not a mathematical formula and depends on the specific facts of the case, with apportionments of 30/70, 50/50, or 60/40 commonly seen in personal injury matters involving multiple defendants.

What is vicarious liability?

Vicarious liability is a legal doctrine under which one party is held legally responsible for the negligent conduct of another, even though the first party was not personally negligent, where the relationship between the parties is one that the law recognises as giving rise to vicarious responsibility. The most common application of vicarious liability is the employer's liability for negligent acts of employees committed in the course of employment, but the doctrine extends to other relationships including agents, apparent agents, and certain non-employee relationships in institutional settings.

The classic application of vicarious liability is the employer-employee relationship. An employer is vicariously liable for the negligent conduct of an employee committed in the course of employment, with the rationale being that the employer has the benefit of the employee's work and the capacity to control the employee's conduct, and so should bear the risk of the employee's negligence affecting third parties. The "course of employment" test has been progressively broadened by the courts, with employers now held vicariously liable for a wider range of employee conduct than was previously the case, including conduct that involves a significant departure from authorised duties.

Vicarious liability has been particularly important in institutional abuse claims, where the negligent conduct is the abuse itself rather than ordinary careless conduct. The High Court of Australia confirmed in Bird v DP (a pseudonym) [2024] HCA 41 that vicarious liability at common law in Australia remains confined to recognised employment or agency relationships and should not be extended merely because a relationship is "akin to employment", such as members of religious orders who are not employees or agents. Queensland's statutory reforms in 2018 and 2019 addressed the position of non-employee abusers in institutional settings through the Civil Liability and Other Legislation Amendment Act 2019, creating a statutory liability regime for institutions rather than expanding common law vicarious liability. The interaction between common law vicarious liability and the statutory provisions is now central to institutional abuse claims in Queensland.

The practical consequence of vicarious liability is that a claimant injured by the negligence of an employee or other person for whom another party is vicariously liable can recover compensation against the vicariously liable party. A patient injured by a hospital nurse's negligence can recover against the hospital. A customer injured by a security guard's negligent conduct can recover against the business that employed the guard. A worker injured by a co-worker's negligence at work can pursue both a workers' compensation claim and a separate negligence claim against the employer for the co-worker's conduct. The practical significance of vicarious liability in catastrophic injury claims is that the institutional defendant's deeper resources make the difference between full compensation and a paper judgment against an individual unable to pay. Queensland's 2019 reforms extended the reach of vicarious liability beyond the traditional employer-employee relationship by creating a statutory liability regime for institutions in respect of abuse by people in positions of trust, addressing the gap left by the High Court's confinement of common law vicarious liability to employment and agency relationships in Bird v DP [2024] HCA 41.

How is negligence proven with evidence?

Negligence is proven with evidence by gathering and presenting the factual material that establishes each of the four elements on the balance of probabilities, with the evidentiary requirements differing for each element and the burden resting on the claimant throughout. The proof of negligence is a process rather than a single moment, with evidence assembled through pre-court procedures, expert reports, witness statements, and documentary records before the matter resolves through settlement or court determination.

Duty of care is the element least often contested through evidence in personal injury claims, because the established duty categories cover most claim types and the existence of a duty is typically clear from the relationship between the parties. Where duty is contested, the evidence focuses on the nature of the relationship, the foreseeability of the harm, and the degree of proximity or control between the defendant and the claimant. The duty question is generally resolved on legal argument rather than factual evidence, with the facts establishing the relationship and the legal analysis determining whether a duty arose.

Breach of duty is proven through evidence of what the defendant did, what a reasonable person in the defendant's position would have done, and how the defendant's conduct fell short. The factual evidence includes witness statements describing the defendant's conduct, documentary evidence such as workplace incident reports or maintenance records, and physical evidence such as photographs of the scene. In professional negligence claims, expert evidence from another professional in the same field is essential to establish what competent practice looks like and where the defendant's conduct departed from it.

Causation is the most evidentially complex element in many personal injury claims, particularly in medical negligence matters where the harm caused by the breach must be separated from the harm that would have occurred from the underlying condition. The medico-legal evidence is central to causation analysis, with treating doctors providing factual evidence of the claimant's condition and independent medical experts providing opinion evidence on whether the breach caused the injury and what the likely outcome would have been with reasonable care. Pre-existing conditions add further complexity to causation, requiring medical evidence on the baseline condition before the breach and the deterioration attributable to the breach.

Damage is proven through medical, financial, and care-related evidence that establishes the nature, extent, and consequences of the injury. The medical evidence covers the diagnosis, treatment, and prognosis through reports from treating practitioners and independent medical examiners. The financial evidence covers past economic loss through tax returns, payslips, and employer statements, and future economic loss through expert reports on residual work capacity and projected earnings. The care evidence covers past care provided through statements from family members and professional providers, and future care needs through occupational therapy and care needs assessments.

The evidence-gathering process operates through the pre-court procedures specific to each compensation scheme, with the claimant required to disclose the evidence supporting the claim and the defendant required to disclose the evidence supporting any defence. The compulsory conference is the primary settlement opportunity in most personal injury claims, attended by the claimant, the defendant's insurer, legal representatives for both sides, and (where appropriate) experts whose evidence is central to the claim. Most personal injury claims in Queensland resolve at compulsory conference or through direct settlement negotiation, with fewer than 1% proceeding to trial.

The strategic and procedural complexity of proving negligence is substantial, particularly where multiple elements are contested, the medical evidence is contested, or multiple defendants are involved. Self-represented claimants face structural disadvantages in evidence-gathering because they lack access to specialist medical experts, occupational therapists, and forensic accountants whose reports drive the evidentiary case. Legally represented Compulsory Third Party (CTP) claimants in Queensland receive on average 7.5 to 8.3 times more compensation than self-represented claimants, according to Motor Accident Insurance Commission and Queensland Treasury data, with the gap reflecting the strength of the evidence assembled and the negotiating position that strong evidence creates. The process of choosing a personal injury lawyer with experience in the relevant claim type, an Accredited Specialist credential where available, and a transparent fee structure is the practical step that determines whether the evidence required to prove negligence is gathered and presented in the strongest available form.
