How to Challenge CTP Scheme Eligibility Decisions with SIRA in Illawarra and South Coast

Residents of Illawarra and South Coast can challenge CTP scheme eligibility decisions by contacting SIRA and submitting evidence. This article explains the process for disputing insurer decisions, including time limits, what to expect during a dispute, and when to seek legal advice.

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 believe an insurer has wrongly denied or limited your eligibility for NSW CTP scheme benefits, you can challenge their decision through the State Insurance Regulatory Authority (SIRA). This article explains the process for residents of Illawarra and South Coast to dispute insurer decisions about CTP scheme eligibility, including how to use SIRA's dispute resolution process and what to expect.

What is the CTP Scheme and How Does Eligibility Work?

The Compulsory Third Party (CTP) scheme in NSW provides compensation for injuries caused by motor vehicle accidents. Eligibility depends on factors like the type of injury, accident circumstances, and whether the injury meets the scheme's definition of a 'threshold injury' or 'whole person impairment'.

Under the Motor Accident Injuries Act 2017, insurers must assess claims based on medical evidence and SIRA's guidelines. If an insurer denies benefits, they must provide a written explanation. If you disagree with their decision, you can challenge it through SIRA.

How to File a SIRA Complaint About CTP Eligibility

To dispute an insurer's decision:

  • Gather evidence: Collect medical records, accident reports, witness statements, and any correspondence with the insurer.
  • Contact SIRA: Use the SIRA claims page to submit a written complaint. Explain why you believe the insurer's decision was incorrect.
  • Follow SIRA's process: SIRA will review your complaint and may request additional information. They will notify you of their decision within 28 days.

SIRA's guidelines state that insurers must provide a clear explanation for denying or limiting benefits. If you believe the insurer misinterpreted the CTP scheme rules, you can request a review of their decision.

Key Considerations for Illawarra and South Coast Residents

Residents of Illawarra and South Coast should note that SIRA's dispute process applies uniformly across NSW. However, you may need to:

  • Verify insurer details: Confirm the correct contact information for the insurer involved in your claim.
  • Seek local advice: Contact a local legal service or community legal centre for assistance with dispute documentation.
  • Check time limits: You must file a complaint with SIRA within 28 days of receiving the insurer's decision. If you miss this deadline, you may lose the right to challenge the decision.

What Happens During a SIRA Dispute?

SIRA will assess whether the insurer followed the correct process. If they find the insurer made an error, they may:

  • Order the insurer to reconsider your claim.
  • Require the insurer to provide additional benefits.
  • Reimburse you for legal costs if the insurer acted unreasonably.

If SIRA upholds the insurer's decision, you may need to pursue further legal options, such as a court application to review the insurer's interpretation of the CTP scheme.

When to Seek Legal Advice

If your claim involves complex issues like:

  • Disputes over 'threshold injury' definitions.
  • Conflicts with the insurer's interpretation of SIRA guidelines.
  • Claims involving long-term care or income loss.

You should consult a solicitor specialising in NSW CTP claims. Legal advice can help ensure your complaint meets all procedural requirements and covers all relevant legal arguments.

Example Scenario

A resident of the South Coast was denied CTP benefits after a car accident. The insurer claimed the injury did not meet the 'threshold injury' definition. The claimant submitted medical evidence showing a spinal nerve-root injury with neurological signs, which SIRA's guidelines confirm qualifies as a threshold injury. SIRA reviewed the complaint and ordered the insurer to reconsider the claim.

Next Steps

CTP scheme eligibility decisions can be complex, especially when disputes involve medical evidence and legal interpretations. If you believe an insurer has wrongly denied your claim, take action within the 28-day deadline. For residents of Illawarra and South Coast, contacting SIRA directly and seeking local legal support can help resolve disputes effectively.
