Proving Psychiatric Injuries in NSW CTP Claims: Evidence and Records to Keep in Auburn

Proving psychiatric injuries in NSW CTP claims requires clinical evidence and detailed documentation. This article explains how to meet SIRA's threshold injury criteria, what records to keep in Auburn, and when to seek legal advice for claims involving psychological injuries.

Current as at 15 October 2026

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).

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 psychiatric injury in a motor accident in NSW, understanding how to prove your claim under the Compulsory Third Party (CTP) scheme is critical. The NSW Motor Accident Injuries Act 2017 and SIRA guidelines set strict rules for psychiatric injuries, requiring specific evidence to meet the 'threshold injury' definition. This article explains what documentation is essential, how SIRA assesses claims, and practical steps to take in Auburn.

What Evidence Proves a Psychiatric Injury Under NSW CTP Laws?

To qualify for CTP compensation, a psychiatric injury must meet the threshold injury criteria outlined in the Motor Accident Guidelines. This requires more than a general diagnosis, it must demonstrate a clinically significant injury. Key evidence includes:

  • Medical records showing a diagnosis of a psychiatric condition (e.g., PTSD, depression, anxiety) with specific clinical signs.
  • Treatment records detailing therapy sessions, medication, and progress notes.
  • Psychiatrist or psychologist reports explaining how the injury relates to the accident and meets the threshold.
  • Witness statements or accident reports confirming the incident's circumstances.

SIRA assesses claims based on the Motor Accident Guidelines, which specify that psychiatric injuries must involve 'significant psychological distress' and 'clinically significant impairment'. Generalised anxiety or stress without clinical evidence typically does not meet the threshold.

Records to Keep in Auburn NSW CTP Cases

In Auburn, claimants and treatment providers must maintain detailed records to support psychiatric injury claims. Essential documents include:

  • Medical records: Ensure your GP or mental health professional documents the injury's connection to the accident. SIRA may request these to verify the injury's origin.
  • Accident reports: Obtain a police report or witness account to establish the incident's details.
  • Therapy records: Keep records of all sessions, including notes on how the injury impacts daily life.
  • Income and employment records: If the injury affects your ability to work, provide evidence of lost wages or reduced capacity.
  • Correspondence: Save all emails or letters from insurers, SIRA, or treatment providers.

A hypothetical example: A cyclist in Auburn suffered a panic attack after a collision. Their psychiatrist documented symptoms matching the threshold criteria, including flashbacks and avoidance behaviour. This evidence helped the claim meet CTP requirements.

How SIRA Assesses Psychiatric Injury Claims

  • SIRA evaluates claims using the
  • Motor Accident Guidelines* and the
  • Motor Accident Injuries Act 2017*. Key factors include:
  • Clinical diagnosis: The injury must be diagnosed by a qualified mental health professional.
  • Link to the accident: Evidence must show the injury directly resulted from the motor accident.
  • Impairment level: The injury must significantly affect the claimant's daily functioning.

SIRA may request additional assessments or clarification if the evidence is unclear. Claims lacking clinical detail are often rejected, as they do not meet the threshold injury definition.

Time Limits and When to Seek Advice

CTP claims must be submitted within 52 weeks of the accident if the injury is a 'threshold injury'. For non-threshold injuries, the 52-week limit does not apply, but delays can still affect compensation. Seek legal advice promptly to:

  • Ensure all required documentation is collected.
  • Challenge SIRA's assessment if your claim is denied.
  • Explore options for disputes or appeals.
