PTSD After Road Trauma: How SIRA Assesses Claims in Blue Mountains and Nepean

This article explains how SIRA assesses PTSD claims under NSW CTP, including evidence requirements, regional processing nuances in the Blue Mountains and Nepean, and time limits. It outlines steps to take if your claim is denied and highlights when to seek legal advice.

Current as at 4 October 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 experienced post-traumatic stress disorder (PTSD) following a road trauma in New South Wales, understanding how the NSW Compulsory Third Party (CTP) scheme handles your claim is essential. SIRA (State Insurance Regulatory Authority) oversees claims under the Motor Accident Injuries Act 2017, which defines what injuries qualify for statutory benefits. This article explains how SIRA evaluates PTSD claims, the evidence required, and regional considerations for the Blue Mountains and Nepean areas.

How SIRA Defines PTSD Claims Under NSW CTP

SIRA assesses PTSD claims based on the Motor Accident Guidelines 2023 and the Motor Accident Injuries Act 2017. To qualify for statutory benefits, your PTSD must meet the 'threshold injury' criteria. This means the injury must result in a clinically significant impact on your daily life, such as persistent anxiety, flashbacks, or avoidance behaviors. SIRA requires medical evidence, including therapist notes and psychological assessments, to confirm the diagnosis and its severity.

Under the Act, 'threshold injuries' include psychological injuries like PTSD that meet specific clinical criteria. However, claims for PTSD are typically limited to statutory benefits (such as treatment and income support) rather than common law damages, unless the injury exceeds the threshold. SIRA evaluates whether your PTSD is a 'threshold injury' by assessing clinical signs like intrusive memories, hyperarousal, or avoidance, as outlined in the guidelines.

Evidence Required for PTSD Claims

To support your PTSD claim, you must provide:

  • Medical records from a registered psychologist or psychiatrist confirming the diagnosis.
  • Documentation of treatment, such as therapy sessions or medication records.
  • Evidence of how PTSD affects your daily life, such as work absences or relationship strain.
  • Any accident reports or witness statements that establish the trauma's connection to the road incident.

SIRA may also request a medical report from a registered practitioner to assess the injury's impact. If your claim involves a 'threshold injury, ' you may be eligible for weekly income payments and treatment benefits under the CTP scheme.

Regional Processing Considerations

While SIRA applies the same legal framework across NSW, processing times and local nuances may vary. In the Blue Mountains and Nepean regions, claims may take longer due to factors like access to specialist mental health services or local SIRA office capacity. SIRA's regional offices handle claims based on the same criteria, but delays can occur during peak periods or if additional evidence is required.

Time Limits and Dispute Options

You have 52 weeks from the accident date to claim statutory benefits for 'threshold injuries.' After this period, weekly income payments and treatment benefits generally stop unless the injury is classified as a 'whole person impairment' (WPI) exceeding the threshold. If your PTSD is not a threshold injury, you may need to pursue a common law damages claim through a solicitor, though this is rare and requires strong evidence of long-term impact.

If SIRA denies your claim, you can request a review or escalate the matter to the NSW Civil and Administrative Tribunal (NCAT). It's crucial to act promptly, as delays can affect your eligibility for benefits.

When to Seek Legal Advice

While SIRA provides a clear framework for statutory benefits, navigating complex claims, especially those involving PTSD, can be challenging. A solicitor can help you understand whether your injury meets the threshold, challenge a denial, or pursue additional compensation if your claim exceeds the statutory limits. Always seek advice before submitting a claim to ensure you meet all requirements.

Next Steps

Understanding how SIRA evaluates PTSD claims is the first step in securing support under the NSW CTP scheme. If you're unsure whether your injury qualifies or need guidance on the process, contact a legal professional. Every claim depends on its own facts, and the Blue Mountains and Nepean regions have specific considerations that may affect your case.
