How SIRA Evaluates Hearing Loss Claims in NSW CTP

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 suffered hearing loss or acoustic trauma from a motor vehicle accident in NSW, understanding how SIRA assesses your claim is critical. SIRA (State Insurance Regulatory Authority) oversees claims under the Motor Accident Injuries Act 2017 (MAIA), which governs NSW Compulsory Third Party (CTP) compensation. This article explains how SIRA evaluates hearing-related injuries, the evidence required, and the legal boundaries for claimants and insurers.

What SIRA Considers for Hearing Loss Claims

SIRA assesses hearing loss claims based on medical evidence and the severity of the injury. Acoustic trauma, often caused by crash forces or airbags, is evaluated using audiograms and clinical reports. Under the MAIA, injuries must meet specific thresholds to qualify for compensation. For example, a hearing loss of 40 decibels or more in one ear may be classified as a 'threshold injury, ' which is the minimum requirement for CTP benefits.

SIRA also considers whether the injury is 'threshold' or more severe. Threshold injuries typically result in limited benefits, while more serious impairments may qualify for higher compensation. The Motor Accident Guidelines provide detailed criteria for assessing hearing loss, including the use of pure-tone audiometry and speech discrimination tests.

Evidence Required for Acoustic Trauma Claims

To prove a hearing loss or acoustic trauma claim, you’ll need:

  • Medical records from an audiologist or ENT specialist, including audiograms and clinical notes.
  • Evidence of the accident, such as police reports, witness statements, or vehicle data.
  • Documentation of pre-existing conditions to establish the injury’s connection to the accident.

SIRA may require a formal impairment assessment by a registered medical practitioner. This assessment must align with the Motor Accident Guidelines to determine whether the injury meets the threshold for compensation.

Time Limits and Dispute Options

CTP claims in NSW have strict time limits. For injuries that only meet the threshold, benefits are generally limited to 52 weeks under the MAIA. If your injury exceeds the threshold, you may be eligible for longer-term support, but this depends on the severity and medical evidence.

If your claim is disputed, you can request a review by SIRA or seek mediation through the NSW Civil and Administrative Tribunal (NCAT). In complex cases, legal advice may be necessary to challenge an insurer’s decision.

A Hypothetical Example

Consider a pedestrian who suffered acoustic trauma from an airbag during a collision. SIRA would assess the claim by reviewing audiograms showing a 45-decibel hearing loss in one ear. If the injury meets the threshold, the claimant would receive weekly benefits and treatment costs for 52 weeks. If the impairment is more severe, such as a 60-decibel loss with speech discrimination issues, the claimant may qualify for additional compensation.

When to Seek Legal Advice

While SIRA provides clear guidelines, interpreting them correctly requires expertise. If your claim is denied, or if you’re unsure about your entitlements, seek advice from a solicitor specialising in NSW CTP claims. Legal professionals can help navigate disputes, ensure all evidence is submitted, and challenge decisions that may be legally flawed.

CTP claims depend on the accident date, injury type, and evidence submitted.
