How SIRA handles traumatic brain injury claims in NSW

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

Traumatic brain injury (TBI) claims under NSW's Compulsory Third Party (CTP) scheme are governed by the Motor Accident Injuries Act 2017 and interpreted by the State Insurance Regulatory Authority (SIRA). If you've suffered a TBI in a motor vehicle accident in Ballina, understanding SIRA's approach to eligibility, documentation and compensation is critical. This article explains how SIRA defines TBI, what evidence is needed, and how regional factors might influence claims.

Key rules behind TBI claims under NSW CTP

SIRA applies the Motor Accident Guidelines to assess whether a brain injury meets the threshold for CTP benefits. A traumatic brain injury is defined as an injury to the brain caused by an external force, such as a blow or jolt, that disrupts normal brain function. For a claim to succeed, the injury must result in a measurable impact on daily life, such as cognitive, emotional or physical impairments.

SIRA distinguishes between 'threshold injuries' and more severe claims. Threshold injuries typically involve soft tissue damage or minor neurological signs, while TBI claims often require evidence of structural brain damage, prolonged recovery or long-term functional limitations. The 52-week statutory benefit period applies to threshold injuries, but TBI claims may extend beyond this if the injury is classified as a 'whole person impairment' under the Motor Accident Guidelines.

Evidence needed for a TBI claim in Ballina

To support a TBI claim, you must provide:

  • Medical documentation confirming the injury, including imaging (e.g., MRI, CT scans) and clinical notes
  • Accident report from the police or relevant authority
  • Witness statements if available
  • Evidence of impact on daily life, such as:
  • Difficulty concentrating or memory loss
  • Changes in mood or behavior
  • Physical symptoms like headaches or dizziness
  • Income records to support claims for lost earnings or care costs

SIRA may request a medical report from a neuropsychologist or neurologist to assess the severity of the injury. In Ballina, claimants should contact SIRA directly to confirm local procedures, as regional offices may have specific requirements for documentation.

Time limits and when to seek advice

Claims must be made within 52 weeks of the accident for threshold injuries, but TBI claims may fall outside this period if the injury is classified as a whole person impairment. If you're unsure whether your injury meets the threshold, seek legal advice promptly. SIRA may also dispute claims if documentation is incomplete or if the injury is not clearly linked to the accident.

In Ballina, claimants should note that SIRA's regional office may have different processing times or local case management practices. If your claim is denied or disputed, you may need to request a review or seek independent legal assessment. Always keep copies of all correspondence with insurers and medical providers.

Example of a TBI claim in practice

Consider a scenario where a cyclist in Ballina suffers a head injury after being hit by a car. The cyclist experiences persistent headaches, memory loss and difficulty concentrating. Medical records show no structural brain damage, but neuropsychological testing reveals significant cognitive impairment. SIRA may classify this as a threshold injury, limiting benefits to 52 weeks. However, if the injury results in long-term functional limitations, the claim could qualify for extended support.

Next steps for claimants in Ballina

If you've suffered a traumatic brain injury in a motor accident in Ballina, the first step is to seek immediate medical attention and document all injuries.
