If you're disputing an insurer's decision in a NSW Compulsory Third Party (CTP) claim, you may need to contact the State Insurance Regulatory Authority (SIRA). The 2017 reforms introduced significant changes to how SIRA handles insurer complaints, affecting claimants in Auburn and other NSW areas. This article explains the process for filing a complaint, the key changes post-2017, and the evidence you’ll need to support your case.

What Steps Can Claimants Take to File a SIRA Complaint?

To dispute an insurer’s decision, claimants must first contact SIRA directly. The process involves submitting a written complaint that outlines the issue, such as denied benefits, delayed payments, or incorrect claim assessments. SIRA provides an online form for complaints, which can be accessed via its official website. Claimants should include details like the claim number, dates of the accident, and a summary of the insurer’s decision.

When filing a complaint, it’s essential to reference the specific section of the Motor Accident Injuries Act 2017 that the insurer’s action allegedly violates. For example, if the insurer refused to pay for treatment, the claimant should highlight how this breaches the Act’s provisions on treatment and care benefits.

How Did the 2017 Reforms Change SIRA’s Approach to Handling Insurer Complaints?

Prior to 2017, SIRA’s complaint process was less structured, with limited guidance on how to challenge insurer decisions. The reforms introduced clearer procedures, including mandatory timelines for SIRA to respond to complaints and stricter rules on insurer conduct. One key change was the introduction of a ‘complaint review’ stage, where SIRA evaluates whether the insurer’s decision aligns with the Motor Accident Guidelines.

The 2017 reforms also expanded SIRA’s authority to investigate insurers’ compliance with the Motor Accident Injuries Act 2017. This includes the power to issue formal notices to insurers who repeatedly fail to meet their obligations. Claimants in Auburn and other NSW areas now have a stronger legal framework to challenge decisions, provided they follow the correct process.

What Evidence Is Needed to Support a SIRA Complaint About an Insurer?

To strengthen your complaint, gather and include the following evidence:

  • Medical records: Documentation of your injuries, treatment, and any assessments confirming the injury meets the threshold for benefits.
  • Insurer correspondence: Emails, letters, or forms from the insurer that show denied claims, incorrect assessments, or delays.
  • Accident reports: Police reports, witness statements, or photos that establish the circumstances of the accident.
  • Income records: Proof of lost wages or other financial impacts if your claim includes weekly income payments.
  • SIRA complaint forms: Completed and submitted forms showing your complaint was filed within the required timeframe.

Evidence must be submitted within 28 days of the insurer’s decision, as per SIRA’s guidelines. Late submissions may be rejected, so prompt action is critical.

A Hypothetical Example: Disputing a Denied Claim

Imagine a claimant in Auburn who was denied weekly income payments after a car accident. The insurer cited the Motor Accident Injuries Act 2017 s 4.4, arguing the injury did not meet the threshold. The claimant could file a SIRA complaint, attaching medical evidence showing the injury meets the threshold. SIRA would then review the insurer’s decision against the Act and the Motor Accident Guidelines.

When to Seek Legal Advice

While SIRA provides a formal complaints process, claimants may need legal assistance to navigate complex issues like contributory fault, overlapping workers’ compensation claims, or disputes over long-term care needs. A solicitor can help ensure your complaint meets all legal and procedural requirements.
