How Personal Injury Compensation is Calculated in Queensland

Personal injury compensation in Queensland is calculated by identifying and valuing each head of damage (including pain and suffering, economic loss, medical expenses, and care needs) then combining those amounts into a total figure and applying statutory reductions. The process does not assign a single fixed value to an injury. Instead, compensation reflects the total measurable impact of the injury on a person's health, income, and daily life, as supported by medical evidence, financial records, and legislative rules. 

Each component of compensation is assessed independently. General damages are determined using the Injury Scale Value (ISV), a statutory scale from 0 to 100 that measures injury severity and long-term impact, while financial losses (including past and future income, superannuation, and treatment costs) are calculated using documentary evidence and expert projections. The final compensation amount is the combined total of all heads of damage, adjusted for life contingencies (vicissitudes) and any percentage of fault attributed to the injured person.

The calculation framework applies across all Queensland personal injury claims, but the rules, thresholds, and outcomes vary depending on the claim type. Motor vehicle accident claims operate under the Motor Accident Insurance Act 1994 (Qld), public liability claims under the Civil Liability Act 2003 (Qld), and workplace injury claims under the Workers’ Compensation and Rehabilitation Act 2003 (Qld). Each scheme applies different ISV conversion tables, impairment thresholds such as Whole Person Impairment (WPI), and eligibility rules, meaning the same injury can produce different compensation outcomes depending on how the accident occurred.

The final value of a personal injury claim is shaped not only by the injury itself, but by how the impact of injury is proved, quantified, and applied within the legal framework. This includes looking at various claim factors such as the strength of medical evidence, the accuracy of financial documentation, the availability of different heads of damage, compliance with procedural requirements, and other factors such as pre-existing conditions, insurer conduct, and legal representation. 

How is Personal Injury Compensation Calculated?

Personal injury compensation in Queensland is calculated by totalling the value of pain and suffering (assessed using the Injury Scale Value system), past and future economic loss, medical and care expenses, and superannuation loss, then applying reductions for contributory negligence and future loss discounting. The final amount depends on the severity of the injury, the claimant's age and earning capacity, the impact on daily life, and whether pre-existing conditions are present. This framework applies all personal injury claim types including motor vehicle, public liability, and workplace injury claims under the Civil Liability Act 2003 (Qld).

In Queensland, personal injury compensation claims are calculated based on the 7 valuation components outlined below. 

• General damages. General damages are assessed using the Injury Scale Value (ISV) system, which rates the injury's severity and impact on a scale of 0 to 100 and converts it to a monetary amount. The ISV is determined by matching the injury to statutory categories in the Civil Liability Regulation 2025, with the position within the prescribed range reflecting the functional impact on daily life, the duration of symptoms, and the long-term prognosis. Where multiple injuries are present, the dominant injury anchors the ISV and secondary injuries may justify an uplift.
• Past economic loss. Past economic loss is calculated by comparing the injured person's pre-accident earnings to their actual post-accident income, using tax returns, payslips, and employer records. The calculation covers base salary, overtime, bonuses, commissions, and allowances. For self-employed claimants, a forensic accountant typically analyses business financial statements to isolate the income reduction attributable to the injuries. A tax adjustment (the Fox v Wood component) is applied to ensure the compensation reflects actual take-home pay rather than an inflated gross figure.
• Future economic loss. Future economic loss is estimated by projecting what the injured person would have earned without the accident and comparing it to their residual earning capacity with the injuries, then converting the difference to a present-day lump sum. Vocational rehabilitation reports assess the injured person's residual earning capacity in alternative occupations and are used by both the claimant and the insurer to support or challenge the future economic loss assessment. The forward-looking assumptions in a future economic loss calculation make this head of damage the most heavily contested in serious injury claims, with insurers frequently challenging both the projected pre-injury trajectory and the assessed residual capacity.
• Superannuation loss. Superannuation loss reflects the employer contributions the injured person missed out on as a result of reduced or lost earnings. It is assessed as a separate head of damage that sits on top of economic loss rather than being included within it. The loss of superannuation calculation applies the current Superannuation Guarantee rate to both past and future economic loss figures, capturing the employer contributions that would have been paid into the claimant's superannuation fund over the affected period.
• Care and assistance. Care and assistance is valued in two parts. Paid commercial care (professional carers, cleaners, gardeners) is calculated at actual cost supported by invoices. Gratuitous care (unpaid assistance from family or friends) is valued at commercial rates for equivalent services, subject to a minimum threshold of 6 hours per week for 6 consecutive months under the Civil Liability Act 2003. Occupational therapy reports provide the independent evaluation of the injured person's functional limitations and care needs that drives the valuation for both past and future care.
• Special damages. Special damages are determined by compiling receipts and invoices for all accident-related expenses already incurred, plus expert estimates of projected future treatment and equipment costs. Common special damages include hospital fees, physiotherapy, medication, psychology, travel to appointments, and home or vehicle modifications. Future special damages require treating specialists to project the likely course of ongoing treatment over the claimant's remaining life expectancy.
• Interest. Interest is calculated by applying prescribed rates to past losses from the date each loss was incurred through to settlement. Interest is payable on past economic loss, past medical expenses, and past special damages, but not on general damages or gratuitous care. In claims that take several years to resolve, interest can add a meaningful amount to the total compensation.

Two reductions are then applied to the combined total. A vicissitudes of life discount reduces all future losses to account for the ordinary risks and uncertainties of life. Contributory negligence reduces the total compensation amount by the percentage the injured person was at fault for the accident.

Each head of damage has specific eligibility criteria. General damages require the injury to meet a minimum severity threshold, gratuitous care requires a minimum period of unpaid care, and some heads are not available in all claim types. 

How is Each Head of Damage Assessed?

Each head of damage in a personal injury compensation claim is assessed using a combination of medical evidence, financial records, and legislative rules specific to the claim type and the category of loss. The methodology for assessing each type of compensation available within a unified personal injury claim is outlined below.

1. General Damages (Pain and Suffering)

General damages are assessed by matching the injured person's condition to statutory injury categories and assigning an Injury Scale Value (ISV) between 0 and 100. General damages are the only head of damage that is not based on a financial loss. The Injury Scale Value measures the severity and impact of the injury on the person's life.

The ISV is assessed by matching the injured person's condition to statutory injury categories set out in the Civil Liability Regulation 2025 (previously Schedule 4 under the 2014 regulation). Each statutory injury category assigns an ISV range rather than a fixed value. The position within the range is determined by the severity of the injury, the functional impact on daily life, the duration of symptoms, the long-term prognosis, and the extent of treatment required.

The ISV is then converted to a general damages dollar amount. The conversion is not linear. Each additional ISV point is worth progressively more, which means the gap in dollar terms between a low ISV and a high ISV is much larger than the gap between adjacent low ISV values.

Where a person has sustained multiple injuries, the ISV system does not add individual values together. The dominant injury (the injury with the greatest overall impact) determines the primary ISV range. Secondary injuries justify a higher position within that range or, where the combined impact exceeds the dominant injury's maximum, an uplift of up to 25% above that maximum.

Workers compensation common law claims use a different ISV conversion table that generally produces lower general damages amounts than the CTP and public liability table for the same ISV.

2. Past Economic Loss

Past economic loss is assessed by comparing the injured person's actual post-accident earnings to what they would have earned without the accident, based on their pre-injury weekly earnings and the duration of lost or reduced income.

Weekly earnings are subject to a statutory cap for high-income earners. Evidence of past economic loss includes tax returns and notices of assessment, payslips and employment contracts, and employer records confirming the date employment ceased or was reduced. The full evidentiary requirements for past economic loss include detailed proof of pre-injury earnings trajectory, the duration of incapacity, and any reduced post-injury work capacity.

3. Future Economic Loss

Future economic loss reflects the long-term reduction in earning capacity caused by the injuries, converted into a lump sum based on the claimant's projected remaining working life. Future economic loss is typically the largest single component in personal injury claims involving serious injuries that prevent the person from returning to their pre-injury occupation.

‍

The calculation requires projecting the injured person's career trajectory, earning potential, and labour market prospects in the absence of the injury, which is why future economic loss is the most contested head of damage in most personal injury claims. Vocational rehabilitation reports assess the injured person's residual earning capacity in alternative occupations and are used by both the claimant and the insurer to support or challenge the future economic loss assessment.

4. Superannuation Loss

Superannuation loss reflects the employer contributions the injured person missed out on as a result of reduced or lost earnings. It is assessed as a separate head of damage that sits on top of economic loss rather than being included within it.

5. Gratuitous Care

Gratuitous care compensates for the value of unpaid assistance provided by family or friends, assessed at commercial rates for equivalent services. The assessment covers help with housework, personal hygiene, meal preparation, transport to medical appointments, and other routine activities.

For CTP (Compulsory Third Party) and public liability claims, gratuitous care is only claimable if the injured person received at least 6 hours of unpaid care per week for a continuous period of at least 6 months. This threshold must be met before any gratuitous care becomes compensable. Workers compensation common law claims do not include gratuitous care as a head of damage. Care evidence includes a diary or log recording the type of assistance provided, the hours per week, and statements from the people who provided the care. Occupational therapy assessments provide an independent evaluation of the injured person's care needs. The detailed mechanics of a gratuitous care claim include thresholds, hourly rate calculations, and exclusions that vary by claim type.

6. Special Damages

Special damages are assessed by compiling receipts and invoices for all accident-related expenses already incurred, and obtaining expert estimates for projected future costs. Special damages are claimed as both past expenses (already incurred) and estimated future expenses (projected costs of ongoing treatment and support).

Common special damages in a personal injury compensation claim include hospital and surgical fees, physiotherapy and rehabilitation costs, medication and medical aids, psychology and counselling, travel to medical appointments, home modifications (ramps, rails, bathroom alterations), and vehicle modifications where the injury affects the person's ability to drive. Special damages are supported by receipts, invoices, and quotes from treatment providers.

7. Interest

Interest compensates the injured person for being out of pocket during the claims process. Interest accrues as simple interest on past economic loss, past gratuitous care, and past special damages from the date of injury.

The interest calculation reflects the time value of money. The injured person has been out of pocket for expenses and lost income throughout the claims process, and interest compensates for that delay. The interest rate applied and the period of accrual depend on the claim type and the date of injury.

What Are the Two Reductions Applied to Total Compensation?

Two reductions are applied to the combined total of all heads of damage before the final compensation amount is determined. These reductions can significantly decrease the total payout.

Vicissitudes of Life Discount

The “vicissitudes of life” discount is a percentage reduction applied to all future losses to account for the ordinary risks and uncertainties of life that may have affected the injured person's earning capacity regardless of the injury.

The discount reflects the statistical probability that a person's working life and health may not have continued uninterrupted even without the accident. Illness, redundancy, career changes, and other life events could have reduced the person's future earnings independently of the injury. The standard discount can be adjusted upward or downward depending on the individual circumstances. A person in a physically demanding occupation with a history of intermittent employment may attract a higher vicissitudes discount. A person in a stable professional role with strong career prospects may attract a lower one.

Contributory Negligence

Contributory negligence is a percentage reduction applied to the entire compensation amount based on the extent to which the injured person was at fault for the accident. The interaction between contributory negligence and the heads of damage framework means that a person assessed at 30% fault receives 30% less across every head of damage. General damages, economic loss, care, special damages, and interest are all reduced by the same percentage.

The court determines the percentage of contributory negligence based on the relative fault of each party. There is no minimum threshold. Common examples include failing to wear a seatbelt in a motor vehicle accident, crossing a road outside a designated crossing area, and ignoring safety warnings on commercial premises.

What Determines the Final Value of a Personal Injury Compensation Claim?

While personal injury compensation is calculated using the heads of damage framework, the final value of a claim is determined by the provable impact of the injury on the person's life, health, income, and independence, as assessed under Queensland legislation and tested through medical evidence, legal process, and negotiation. Two people with identical injuries receive different compensation amounts because the outcome depends not on what was lost, but on what can be documented, quantified, and argued.

The 8 factors that shape the final compensation value of a personal injury compensation claim are outlined below.

• Medical evidence. The strength and detail of the medical evidence is the single most influential factor in the final compensation amount for a compensation claim. Medico-legal reports from independent medical examiners, treatment records, diagnostic imaging, and specialist opinions together establish the severity of the injury, the prognosis for recovery, and the degree of permanent impairment. A claim supported by consistent, detailed medical evidence across multiple practitioners achieves a higher compensation outcome than a claim with limited or contradictory medical records.

• Formal Injury Scale Value (ISV) assessment. The ISV determines the general damages component of the claim. Two injuries that appear similar on a severity scale attract different ISV assessments depending on how the injury presents in medical evidence, the specific statutory injury category, and the functional impact on the individual person.

• Pre-existing conditions. A pre-existing condition does not prevent a person from claiming compensation, but it affects the amount. The compensation reflects the deterioration caused by the accident, not the underlying condition itself. The assessment of how much the accident aggravated the pre-existing condition is one of the most contested areas in personal injury claims.

• Quality of legal representation. The skill and experience of the personal injury lawyer handling the claim directly affects the compensation outcome. Analysis of MAIC and Queensland Treasury data indicates that legally represented Compulsory Third Party (CTP) claimants receive around 7.5 to 8.3 times more compensation on average than self-represented claimants, according to commentary published by the Australian Lawyers Alliance and the Queensland Law Society. These are scheme-wide averages and do not mean every claim increases by a fixed multiple, but the data consistently shows that represented claimants achieve substantially better compensation outcomes across the Queensland CTP scheme.

• Insurer conduct and negotiation strategy. The insurer or liable party's approach to the claim affects both the timeline and the final compensation amount. Some insurers make reasonable early offers based on the available evidence. Others adopt adversarial strategies that dispute liability, challenge the severity of the injury, or delay the claims process.

• Legal thresholds and procedural compliance. Several legislative thresholds and procedural requirements affect whether certain heads of damage are available and how the claim progresses. The Whole Person Impairment (WPI) threshold determines whether general damages can be claimed in CTP motor vehicle accident cases. The gratuitous care threshold determines whether unpaid care is compensable. Failure to comply with mandatory procedural steps, such as lodging a Notice of Accident Claim Form within the prescribed timeframes, can reduce or extinguish the claim entirely.

• Timing and medical stabilisation. The timing of the compensation assessment affects the final value because the claim cannot be properly valued until the injury has stabilised. Maximum medical improvement is the point at which the injured person's condition is unlikely to improve further with ongoing treatment. Settling a claim before maximum medical improvement risks undervaluing the future economic loss and general damages components, and understanding how long a personal injury claim takesto resolve helps set realistic expectations about when the claim can be properly valued.

• Tax implications and statutory refunds. Personal injury compensation in Queensland is generally not subject to income tax, but certain components interact with other statutory obligations. Workers compensation common law settlements require the refund of statutory benefits already received (weekly payments and medical expenses paid by WorkCover). Medicare and Centrelink may also recover amounts from the settlement where the injured person received public health treatment or income support payments during the claim period. These refunds reduce the net amount the injured person receives from the gross settlement figure.

Does the Type of Accident Change How Personal Injury Compensation is Calculated?

Yes, the type of accident changes how personal injury compensation is calculated because each claim pathway in Queensland applies different ISV conversion tables, care thresholds, WPI requirements, and procedural rules. The same injury produces different compensation outcomes depending on whether the claim is a CTP motor vehicle accident claim, a public liability claim, or a workers compensation common law claim.

Each of the 3 most common types of personal injury claim is outlined below.

CTP Motor Vehicle Accident Claims

CTP motor vehicle accident claims are governed by the Motor Accident Insurance Act 1994 (Qld) and funded through Compulsory Third Party (CTP) insurance attached to vehicle registration. Every registered vehicle in Queensland carries CTP insurance, and the CTP insurer of the at-fault vehicle is liable to pay compensation to the injured person.

General damages in a CTP claim are assessed using a banded ISV conversion table where each ISV point corresponds to a dollar amount that increases at a steeper rate for higher values. The injured person must meet the Whole Person Impairment (WPI) threshold before general damages become available. Gratuitous care is claimable if the injured person received at least 6 hours of unpaid care per week for a continuous period of at least 6 months. The CTP claims process follows mandatory compliance steps under the Motor Accident Insurance Act 1994, including lodgement of a Notice of Accident Claim Form, a liability decision by the insurer, and a compulsory conference before court proceedings can be filed.

Public Liability Claims

A public liability claim arises when a person is injured due to the negligence of a property owner, occupier, business, or other party that owes a duty of care. Common public liability claims involve slip and fall injuries on commercial premises, injuries caused by defective products, and injuries sustained in public spaces where a hazard was not adequately managed.

General damages in a public liability claim use the same banded ISV conversion table as CTP claims. There is no WPI threshold for public liability claims. The injured person is entitled to claim general damages regardless of the degree of permanent impairment. Gratuitous care follows the same threshold as CTP claims. The key difference in public liability claims is that the injured person must prove that the defendant owed a duty of care, breached that duty, and that the breach caused the injury. Liability is more frequently disputed in public liability claims than in rear-end motor vehicle accidents where fault is generally clear.

Workers Compensation Common Law Claims

Workers compensation common law claims arise when a worker is injured at work due to the negligence of their employer or a third party. Queensland workers compensation operates as a hybrid system under the Workers' Compensation and Rehabilitation Act 2003 (Qld), combining statutory no-fault benefits (weekly payments and medical expenses through WorkCover Queensland) with a separate common law damages pathway that requires proof of negligence.

General damages in a Queensland workers compensation common law claim are assessed using the ISV framework set out in Schedule 14 of the Workers' Compensation and Rehabilitation Regulation 2025, which maps each ISV to a specific dollar amount that is generally lower than the CTP and public liability conversion table at the same ISV. Queensland removed the minimum WPI threshold for accessing common law damages for injuries on or after 31 January 2015, meaning injured workers can pursue a common law claim regardless of their assessed WPI provided negligence is established. Workers with a DPI of 20% or below must elect between a statutory lump sum and common law damages. Gratuitous care is not claimable as a head of damage in workers compensation common law claims. Future economic loss is discounted at a higher rate than CTP and public liability claims.

The total compensation for a personal injury claim varies significantly by injury type and severity. Indicative compensation ranges for common injury types are available using a personal injury compensation calculator, but as claims are so individual the best way to establish potential claim value is a consultation with a qualified lawyer. 

What Evidence is Needed to Calculate Personal Injury Compensation?

The evidence needed to calculate personal injury compensation in Queensland falls into 3 categories. Medical evidence establishes the nature and severity of the injury, financial evidence quantifies the economic losses, and care evidence documents the assistance the injured person requires. The quality and completeness of the evidence across all 3 categories is what determines whether each head of damage is assessed at the lower or upper end of its range.

Medical Evidence

Medical evidence is the foundation of every head of damage in a personal injury compensation claim. The Injury Scale Value (ISV) assessment, the prognosis for recovery, the degree of permanent impairment, and the need for future treatment are all established through medical evidence.

The 5 types of medical evidence used in a Queensland personal injury compensation claim are outlined below.

• Treating doctor records. Treatment notes from general practitioners, surgeons, and allied health providers document the injury from the date of the accident through the recovery period. Treating doctor records establish the timeline of symptoms, the treatment provided, and the clinical response to that treatment.
• Medico-legal reports. Medico-legal reports describe the nature and severity of the injury, the degree of permanent impairment, the prognosis for future recovery, and the impact of the injury on the person's capacity to work and function. The purpose of Independent Medical Examination reports is to provide an objective assessment of the injury for the purpose of the compensation claim. Both the claimant's legal representative and the insurer typically obtain their own medico-legal reports from different specialists.
• Diagnostic imaging. MRI scans, X-rays, CT scans, and other imaging confirm structural damage, abnormalities, or degenerative changes. Diagnostic imaging provides objective evidence that supports or challenges the reported symptoms and clinical findings.
• Specialist opinions. Orthopaedic surgeons, neurologists, psychiatrists, pain medicine specialists, and rehabilitation physicians provide specialist opinions on injuries within their area of expertise. Specialist opinions carry significant weight in the ISV assessment, particularly where the injury involves complex or contested diagnoses.
• Psychiatric assessment. Psychological injuries are assessed using the Psychiatric Impairment Rating Scale (PIRS), a standardised tool that rates functional impairment across 6 areas of daily living. The PIRS assessment is carried out by a psychiatrist and is required under the Civil Liability Regulation 2025 for any claim that includes a mental disorder as a compensable injury.

Financial Evidence

Financial evidence is used to calculate past economic loss, future economic loss, and superannuation loss in a personal injury compensation claim. The accuracy of the economic loss calculation depends on the quality of the financial records provided.

The financial evidence used to calculate economic loss in a compensation claim includes tax returns and notices of assessment for the 3 to 5 years before the accident, payslips and employment contracts, employer records confirming the injured person's role, hours, pay rate, and any planned promotions or pay increases, superannuation statements, and business financial records (for self-employed claimants).

Care Evidence

Care evidence is used to calculate the gratuitous care component of a personal injury compensation claim. Gratuitous care is only claimable in CTP and public liability claims where the care threshold has been met.

Care evidence includes a diary or log recording the type of assistance provided, the hours per week, and the duration of the care period. Care evidence also includes statements from the people who provided the care. Occupational therapy reports provide an independent assessment of the injured person's functional limitations and the level of care required, which establishes the basis for both past and future care calculations.

What Other Factors Reduce the Value of a Personal Injury Compensation Claim?

Beyond contributory negligence and the vicissitudes discount (which are applied as percentage reductions to the total compensation amount), 3 additional factors reduce the value of a personal injury compensation claim.

Pre-Existing Conditions

A pre-existing condition reduces a compensation claim by limiting the compensable injury to the deterioration caused by the accident, not the underlying condition itself. The injured person is compensated for the aggravation of their condition, not the condition as a whole.

Pre-existing conditions are one of the most contested issues in personal injury claims because the boundary between the pre-existing condition and the accident-related deterioration is often difficult to establish in medical evidence. Insurers frequently argue that the injured person's symptoms are attributable to the pre-existing condition rather than the accident.

Failure to Mitigate

Failure to mitigate reduces a compensation claim by the extent to which the injured person's unreasonable conduct after the accident increased the loss. The duty to mitigate requires the injured person to take reasonable steps to limit their losses and promote their recovery.

Common examples of failure to mitigate include refusing recommended medical treatment or surgery that would improve the condition, failing to attend rehabilitation or physiotherapy, not attempting a return to work when medically cleared, and incurring unnecessary expenses that could have been avoided.

Late Lodgement and Procedural Non-Compliance

Late lodgement and procedural non-compliance reduce or extinguish a compensation claim by preventing the injured person from accessing the claims process or limiting the heads of damage available. In Queensland, each claim type has mandatory lodgement deadlines and procedural steps that must be followed.

For example, motor vehicle accident claims require a Notice of Accident Claim Form to be lodged with the Compulsory Third Party insurer within 9 months of the accident, with an absolute bar at 3 years. Workers compensation common law claims must be filed within 3 years of the date of injury. Late lodgement does not automatically bar the claim in all circumstances, but it can result in the loss of specific entitlements.

How Does Whole Person Impairment (WPI) Affect Personal Injury Compensation?

Whole Person Impairment (WPI) affects personal injury compensation by determining whether the injured person can access general damages and, in workers compensation claims, whether common law proceedings can be filed at all. WPI is a medical assessment that rates permanent physical and psychological impairment as a percentage of the whole body.

WPI Thresholds by Claim Type

The WPI threshold that applies to a personal injury claim depends on the type of accident and the legislative scheme that governs the claim.

The requirements for each personal injury claim type in Queensland where WPI is relevant are outlined below.

• Motor vehicle accident claims. A motor vehicle accident claimant must meet a prescribed WPI threshold before general damages become available. Claimants whose injuries fall below the WPI threshold can still claim economic loss, care, and special damages but receive no compensation for pain and suffering.
• Public liability claims. Public liability claimants are entitled to claim general damages at any level of assessed impairment. There is no WPI threshold for general damages in public liability claims under the Civil Liability Act 2003.
• Medical negligence claims. Medical negligence claimants face the same position as public liability. There is no WPI threshold for general damages under the Civil Liability Act 2003.
• Workers compensation common law claims. Queensland removed the minimum WPI threshold for accessing common law damages in workers compensation claims for injuries occurring on or after 31 January 2015. Injured workers can pursue a common law claim for employer negligence regardless of their assessed WPI, provided they can establish negligence. Workers with a Degree of Permanent Impairment (DPI) of 20% or below must elect between receiving a statutory permanent impairment lump sum or pursuing common law damages. Workers assessed above 20% DPI may be entitled to access both. A separate 15% DPI threshold applies only to additional lump sum compensation for workers who require moderate-to-total daily care as a result of their injuries.

How Does Whole Person Impairment (WPI) Affect Personal Injury Compensation?

Whole Person Impairment (WPI) affects personal injury compensation by determining whether the injured person can access general damages and, in workers compensation claims, influencing the election between statutory and common law pathways. WPI is a medical assessment that rates permanent physical and psychological impairment as a percentage of the whole body using the American Medical Association (AMA) Guides to the Evaluation of Permanent Impairment.

WPI Thresholds by Claim Type

The WPI threshold that applies to a personal injury claim depends on the type of accident and the legislative scheme that governs the claim.

The requirements for each personal injury claim type in Queensland where WPI is relevant are outlined below.

• Motor vehicle accident claims. A motor vehicle accident claimant must meet a prescribed WPI threshold before general damages become available. Claimants whose injuries fall below the WPI threshold can still claim economic loss, care, and special damages but receive no compensation for pain and suffering.
• Public liability claims. Public liability claimants are entitled to claim general damages at any level of assessed impairment. There is no WPI threshold for general damages in public liability claims under the Civil Liability Act 2003.
• Medical negligence claims. Medical negligence claimants face the same position as public liability. There is no WPI threshold for general damages under the Civil Liability Act 2003.
• Workers compensation common law claims. Queensland removed the minimum WPI threshold for accessing common law damages in workers compensation claims for injuries occurring on or after 31 January 2015. Injured workers can pursue a common law claim for employer negligence regardless of their assessed WPI, provided they can establish negligence. Workers with a Degree of Permanent Impairment (DPI) of 20% or below must elect between receiving a statutory permanent impairment lump sum or pursuing common law damages. Workers assessed above 20% DPI may be entitled to access both.

What Do Different WPI Percentages Mean for Compensation?

The WPI percentage reflects the degree of permanent impairment but does not directly determine the dollar amount of compensation. A Whole Person Impairment (WPI) in the 0-10% range represents minor to moderate permanent impairment such as a resolved soft tissue injury with some residual restriction. A WPI in the 16-30% range represents significant permanent impairment such as a spinal fusion with substantial functional limitation or a moderate traumatic brain injury with cognitive deficits. A WPI above 50% typically involves catastrophic injuries such as severe traumatic brain injury, spinal cord injury resulting in paraplegia or quadriplegia, or multiple amputations, where total compensation can exceed several million dollars.

A higher WPI generally supports a higher ISV assessment and a larger economic loss claim, but the relationship is not formulaic. A person with significant ongoing pain and functional limitation but limited measurable impairment on the AMA criteria may have a low WPI percentage but a relatively higher ISV. The WPI percentage is one input into the compensation assessment, not a direct determinant of the dollar amount.

Is There a Maximum Personal Injury Compensation Amount in Queensland?

No, there is no fixed cap on total personal injury compensation in Queensland, but the general damages (pain and suffering) component is subject to a statutory maximum that is indexed annually. The current maximum applies at the highest ISV of 100 and represents the ceiling for the most catastrophic injuries. Economic loss, gratuitous care, and special damages have no legislated maximum. The only ceiling on economic loss is the weekly earnings cap based on Queensland Ordinary Time Earnings (QOTE), which limits the income figure used to calculate lost earnings but does not cap the total economic loss amount over the injured person's remaining working life.

Total compensation for catastrophic injuries regularly exceeds $2,000,000 and can exceed $5,000,000 where the injured person is young, had high pre-injury earnings, and requires lifetime care. The largest personal injury settlement publicly reported in Queensland is approximately $20,000,000, awarded to Chrys Baker after a catastrophic brain injury in a motor vehicle accident. The highest compensation amounts in Queensland personal injury claims involve severe traumatic brain injuries and spinal cord injuries resulting in quadriplegia, where future economic loss, professional care costs, and medical expenses accumulate over decades.

Workers compensation statutory lump sum payments have a separate maximum for permanent impairment, calculated as a rate per percentage point of permanent impairment. The statutory lump sum is separate from and cannot be combined with a common law damages settlement.

Do You Need a Lawyer to Make a Personal Injury Compensation Claim?

No, a lawyer is not legally required to make a personal injury compensation claim in Queensland, but claimants who engage legal representation receive substantially higher compensation on average than those who represent themselves. Legally represented CTP claimants receive around 7.5 to 8.3 times more compensation on average than self-represented claimants, according to Queensland Motor Accident Insurance Commission (MAIC) data and Queensland Treasury figures reported in the Queensland Law Society’s Proctor journal.

The compensation gap between represented and unrepresented claimants reflects several factors, most of which centre around the difference in knowledge, evidence quality, and negotiation leverage when a lawyer is involved. A qualified personal injury lawyer identifies heads of damage the claimant may not know exist, obtains medical evidence that supports a higher ISV (Injury Scale Value) assessment, engages forensic accountants and vocational experts to quantify economic loss, and negotiates with the insurer from a position of experience with comparable claim outcomes. Self-represented claimants typically accept lower settlement offers because they have no benchmark for what their claim is actually worth and no way to challenge the insurer's valuation.

How Are Personal Injury Compensation Claims Paid For?

Most personal injury lawyers in Queensland operate on a "no win, no fee" basis. In essence, No Win No Fee means the injured person does not pay legal fees unless the claim succeeds. That being said, cost agreements and conditions vary between different lawyers and law firms, which is why it's important to have a complete understanding of the fee structure before signing anything. Legal costs in a successful personal injury claim are typically recovered in part from the liable party or their insurer in addition to the compensation amount. The net compensation the injured person receives after legal costs is still substantially higher for represented claimants than the total amount self-represented claimants receive.

Why is general damages different from total compensation?

General damages and total compensation are two different measures that are often confused in personal injury claims. General damages represent the pain and suffering component of a claim, whereas total compensation includes general damages plus all other heads of damage (economic loss, superannuation, care and assistance, special damages, and interest) combined into a single figure.

General damages are only one of seven components in a personal injury claim. In serious injury claims, general damages often represent the smallest proportion of the total payout because economic loss, care needs, superannuation, and other heads of damage typically make up the majority of the total compensation. A general damages figure viewed in isolation does not reflect what the claim is actually worth.

A person with a moderate back injury who uses a compensation calculator might see an estimate of approximately $35,000 based on their ISV and assume that is their total claim value. The actual total compensation for that person, including 2 years of lost income, ongoing treatment costs, superannuation loss, and care and assistance, may exceed $250,000 when all heads of damage are properly assessed. The general damages component in that claim represents a small fraction of the total.

The distinction works in the opposite direction for minor injuries. A person with a soft tissue injury at a low ISV may have general damages under $10,000, but their total compensation after adding modest economic loss, medical expenses, and interest may reach $15,000 to $25,000. Presenting the general damages figure alone understates the claim by 50% to 70%.
