It outlines medical documentation, accident records, and steps to preserve evidence, while highlighting time limits and dispute resolution options under SIRA's guidelines.

Current as at 16 August 2026

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).

If you've suffered a traumatic brain injury in a motor vehicle accident in the Blue Mountains or Nepean, understanding what evidence to collect is critical. Under NSW's Compulsory Third Party (CTP) scheme, traumatic brain injuries are covered under the Motor Accident Injuries Act 2017. This article explains the evidence required to support your claim, how SIRA's guidelines apply to your region, and practical steps to preserve records. Time limits and dispute resolution options are also outlined.

What Evidence Supports a Traumatic Brain Injury Claim?

To claim compensation for a traumatic brain injury under NSW CTP, you must provide evidence of:

  • Medical documentation - Detailed records from a medical practitioner confirming the injury, including imaging (MRI/CT scans), neurological assessments, and treatment plans. SIRA's guidelines emphasize that injuries must meet the 'threshold injury' criteria, which includes neurological signs or functional impairments.
  • Accident details - Police reports, witness statements, and photographs of the scene. For road users in the Blue Mountains or Nepean, local authorities may have specific protocols for documenting accidents.
  • Witness accounts - Statements from people who saw the incident, especially if they can describe the collision or the injured person's condition.
  • Medical bills and treatment records - Proof of expenses incurred for diagnosis, therapy, or ongoing care.
  • Impact on daily life - Evidence of how the injury affects your ability to work, drive, or perform everyday tasks, such as doctor's notes or a psychologist's report.

How SIRA's Guidelines Apply to Traumatic Brain Injuries

SIRA's Motor Accident Claims page states that traumatic brain injuries are covered under the CTP scheme, but the injury must be 'threshold' under the Motor Accident Guidelines. This means the injury must result in neurological signs or functional impairments, such as memory loss, speech difficulties, or coordination problems. For example, a cyclist in the Blue Mountains who suffered a head injury requiring hospitalization and cognitive therapy would qualify, while a minor concussion without lasting effects may not.

Practical Steps to Preserve Evidence

  1. Seek immediate medical attention - Even if symptoms seem minor, a medical professional can document the injury. Delayed treatment may affect your claim.
  2. Document the accident scene - Take photos of the vehicle damage, road conditions, and any visible injuries. In the Nepean area, ensure you capture details of the location, such as traffic signs or road markings.
  3. Keep all correspondence - Save emails, letters, or messages from insurers, medical providers, or police. SIRA's 'Making a Motor Accident Claim' page advises that insurers may request additional documentation during the process.
  4. Record ongoing treatment - Track all medical appointments, therapies, and medications. This helps demonstrate the injury's long-term impact.

Time Limits and Dispute Resolution

You have five years from the date of the accident to make a claim under NSW CTP laws. However, certain benefits, such as weekly income payments, may be limited after 52 weeks if the injury is classified as a 'threshold injury' under the Act. If your claim is denied or you disagree with the assessment, you can:

  • Appeal through SIRA's internal review process - SIRA provides a formal process to challenge decisions, as outlined on their 'What You Can Claim' page.
  • Seek independent legal advice - A solicitor can help you navigate disputes, especially if the injury's severity or long-term effects are in question.

When to Seek Legal Advice

If your traumatic brain injury claim involves complex medical evidence, disputes over injury severity, or questions about your eligibility, consult a solicitor. Legal professionals can help you understand how SIRA's guidelines apply to your specific circumstances and ensure all required documentation is submitted.
