How to File a SIRA Complaint Against a CTP Insurer in Western Sydney

If you believe a CTP insurer in Western Sydney has breached its obligations under NSW law, you can lodge a complaint with the State Insurance Regulatory Authority (SIRA). SIRA oversees compliance with the Motor Accident Injuries Act 2017 and ensures insurers follow their legal duties. This guide explains how to file a complaint, how SIRA interprets its rules, and what evidence to include.

What Is a SIRA Complaint and When to Use It

SIRA complaints are formal requests to investigate an insurer’s actions. You can use this process if an insurer has: denied a claim unfairly, delayed payments, or failed to follow its own guidelines. SIRA will review the insurer’s decision and determine if it complies with NSW law. This process is distinct from making a claim for compensation, as it focuses on regulatory compliance rather than assessing injury severity.

How SIRA Interprets Its Rules in Western Sydney

SIRA applies the Motor Accident Injuries Act 2017 uniformly across NSW, including Western Sydney. When resolving complaints, SIRA considers:

  • Whether the insurer followed its own published claims guidelines
  • Whether the insurer’s decision aligns with the Act’s statutory obligations
  • Whether the insurer provided clear reasoning for its decision

SIRA’s rulings are based on official interpretations of the law, not individual case outcomes. For example, if an insurer refuses to pay for treatment, SIRA will check if the treatment meets the Act’s criteria for “treatment and care benefits” under section 4.4.

Evidence Needed for a SIRA Complaint

To support your complaint, gather:

  • A copy of the insurer’s decision letter
  • Evidence of the insurer’s non-compliance (e.g., delays, incorrect calculations)
  • Medical records showing treatment was denied or delayed
  • Correspondence with the insurer

SIRA requires clear documentation to assess whether the insurer followed its legal duties. For instance, if an insurer refuses to pay for a soft tissue injury, you must show it did not meet the threshold injury criteria in the Motor Accident Guidelines.

Practical Steps to Lodge a SIRA Complaint

  1. Contact SIRA directly via their website or phone to request a complaint form
  2. Complete the form with details of the insurer’s actions and how they breached the law
  3. Submit evidence to support your claims
  4. Wait for a response, SIRA typically responds within 28 days

SIRA will notify the insurer of your complaint and may request additional information. This process does not halt the insurer’s decision, so you may need to pursue a separate claim for compensation if the insurer’s actions impacted your rights.

Time Limits and When to Seek Advice

You must lodge a SIRA complaint within 28 days of receiving the insurer’s decision. If you’re unsure whether the insurer’s actions breached the law, seek advice before the deadline. SIRA’s rules are complex, and delays can reduce your ability to challenge an insurer’s decision.

Example of a SIRA Complaint Scenario

A driver in Western Sydney receives a letter from their CTP insurer denying treatment for a soft tissue injury. The insurer claims the injury does not meet the threshold injury criteria. The driver lodges a SIRA complaint, arguing the insurer failed to apply the Motor Accident Guidelines correctly. SIRA reviews the insurer’s decision and finds it did not follow its own published treatment guidelines, leading to a formal reprimand of the insurer.

Next Steps After a SIRA Complaint

If SIRA finds the insurer breached its obligations, it may:

  • Require the insurer to pay your claim
  • Issue a formal warning to the insurer
  • Recommend changes to the insurer’s claims process

If the insurer does not comply, you may need to pursue a separate claim for compensation. Always seek legal advice if your claim is denied or if you face disputes over injury severity.

Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
