Understanding Traumatic Brain Injury in NSW CTP Claims
A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).
A traumatic brain injury (TBI) sustained in a motor accident in Greater Sydney may entitle you to compensation under the NSW Compulsory Third Party (CTP) insurance scheme. This claim is governed by the Motor Accident Injuries Act 2017 (MAIA), which sets out the legal framework for compensation. To establish entitlement, you must demonstrate that the injury arose from the accident and that it has caused measurable harm, including physical, psychological or cognitive effects. The CTP scheme provides benefits for treatment and care, weekly income payments, and, in some cases, damages for non-economic loss. The process is not automatic and depends on the nature and severity of the injury, the evidence available, and whether the injury meets the legal thresholds for compensation.
Critical Evidence and Records to Collect
To support a TBI claim, you must preserve a range of evidence and records. The most important include:
- Medical records from the accident and ongoing treatment, including emergency department notes, neuroimaging reports (such as CT or MRI scans), and follow-up assessments by neurologists or neuropsychologists.
- A formal diagnosis of traumatic brain injury from a medical practitioner, including details of the injury mechanism and any identified neurological deficits.
- Documentation of symptoms such as headaches, memory problems, concentration difficulties, mood changes, or sleep disturbances, particularly if they have persisted beyond the initial recovery phase.
- A record of any changes in daily functioning, including difficulties with work, study, household tasks, or social activities.
- Witness statements from people who observed your behaviour immediately after the accident or who have noticed changes in your abilities over time.
- Photographs or videos of the accident scene, vehicle damage, or your condition immediately after the incident, if available.
- A copy of the police report, if one was made, and any accident report completed at the scene.
- Records of lost income, including payslips and employer letters confirming time off work.
These records form the foundation of your claim and must be kept secure and accessible.
How NSW CTP Law Defines Acceptable Evidence for TBI
Under the MAIA, a traumatic brain injury is recognised as a potentially compensable injury. The law does not require proof of a specific type of brain trauma, but it does require that the injury is medically confirmed and has caused a measurable impact on your life. Evidence must demonstrate a causal link between the motor accident and the brain injury, and that the injury has resulted in a whole person impairment (WPI) of at least 10%. This WPI is assessed by an independent medical expert using the Motor Accident Guidelines.
The law also distinguishes between injuries that are considered 'threshold' injuries and those that may allow for damages. A TBI may qualify as a threshold injury if it results in a WPI of 10% or more but does not meet the criteria for a higher-level injury. In such cases, you may be entitled to treatment and care benefits and weekly income payments, but damages for non-economic loss are generally not available unless the injury exceeds the threshold and meets the criteria for a higher-level injury. The law provides that if your only injuries are threshold injuries, weekly benefits and treatment and care benefits are generally limited after 52 weeks, as set out in the MAIA.
Practical Steps to Protect Your Claim
Immediately after a motor accident involving a head injury, you should:
- Seek urgent medical attention, even if symptoms appear mild or delayed. Do not assume that a lack of immediate symptoms means you are uninjured.
- Request a copy of all medical records, including imaging results, from every healthcare provider involved in your treatment.
- Notify your CTP insurer as soon as possible, providing details of the accident and your injuries.
- Keep a daily journal of your symptoms, functional limitations, and any changes in mood or behaviour.
- Avoid making statements to insurers or third parties about your injury without first consulting a legal professional.
For example, a 32-year-old office worker in Sydney’s western suburbs was involved in a rear-end collision while driving. Although not unconscious, they reported persistent headaches, difficulty concentrating, and irritability over the following weeks. Medical imaging revealed no structural damage, but a neuropsychological assessment confirmed a mild TBI with a WPI of 12%. This evidence supported a claim for treatment and care benefits and weekly payments, but not damages, as the injury was classified as a threshold injury.
Time Limits and Dispute Options
A claim for compensation must be made within a specific timeframe. While the CTP insurer may not require a formal claim within 3 years of the accident, it is essential to act promptly to preserve evidence and ensure your rights are not compromised. Delays in reporting or seeking treatment may affect the insurer’s assessment of your claim.
If your claim is denied or you disagree with the insurer’s assessment of your injury or entitlements, you may request a review or apply to the NSW Civil and Administrative Tribunal (NCAT) for a determination. You may also seek a second medical opinion to support your case.
