Current as at 15 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 been injured in a rear-end collision and are disputing your CTP claim in Auburn, understanding your options is critical. NSW law provides structured pathways to resolve disputes without litigation, but claimants must act promptly and prepare evidence. This article explains how SIRA evaluates claims, what steps to take when disagreements arise, and how to challenge decisions within the legal framework.

How SIRA Handles Disputes in Rear-end Collision Claims

SIRA (State Insurance Regulatory Authority) oversees all CTP claims under the Motor Accident Injuries Act 2017. When a dispute arises, SIRA assesses whether the claimant's injuries meet the statutory definition of a 'threshold injury' or qualify for damages. For rear-end collisions, the key issue is whether the injury meets the spinal nerve-root qualification outlined in the Motor Accident Guidelines.

If SIRA denies a claim, claimants can request a review by submitting a written appeal within 28 days of the decision. This process involves providing additional medical evidence, such as updated treatment records or a second opinion from a registered medical practitioner. SIRA may also refer the case to the Personal Injury Commission (PIC) for a medical dispute resolution pathway, which involves an independent medical assessment.

Practical Steps for Resolving Disputes in Auburn

To resolve a dispute effectively, claimants should:

  • Document all evidence: This includes medical records, accident reports, witness statements, and photographs of the collision site.
  • Submit a formal review request: Use SIRA's online portal or contact their Auburn office to lodge a written appeal within the 28-day timeframe.
  • Engage a medical expert: A specialist in musculoskeletal injuries can provide evidence to challenge SIRA's assessment of the injury's severity.
  • Seek independent advice: A solicitor with CTP experience can help navigate the review process and identify potential errors in SIRA's evaluation.

Time Limits and Legal Boundaries

CTP claims must be submitted within 28 days of the accident, though extensions may apply for complex cases. If a dispute arises after this period, SIRA may refuse to reconsider the claim. Additionally, the 52-week statutory benefit period applies to threshold injuries, meaning weekly payments and treatment benefits stop after 52 weeks unless the claimant qualifies for a higher impairment rating.

Claimants must also be aware that SIRA's decisions are binding unless challenged through the PIC's medical dispute pathway. This process requires a formal request for a medical review, which is only available if the claimant disputes the severity of their injury.

Example: Challenging a SIRA Decision

Consider a claimant who suffered a soft-tissue injury after a rear-end collision. SIRA denied the claim, arguing the injury did not meet the threshold definition. The claimant then submitted a review request, including a medical report from a neurologist confirming spinal nerve-root involvement. SIRA referred the case to the PIC, which ordered an independent assessment. The final decision confirmed the injury met the threshold, resulting in a successful claim.

When to Seek Legal Advice

Disputes over CTP claims often require legal expertise, especially when SIRA's decision is based on a misinterpretation of the Motor Accident Guidelines. A solicitor can help identify errors in the assessment process, such as incorrect application of the 52-week benefit period or failure to consider a claimant's pre-existing conditions.

If you're facing a dispute over your rear-end collision claim, it's essential to act quickly. SIRA's review process is time-sensitive, and delays can jeopardize your ability to challenge a decision. By gathering evidence, understanding your legal rights, and seeking professional guidance, you can improve your chances of a fair outcome.
