How SIRA Assesses Traumatic Brain Injury Claims in NSW

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).

Traumatic brain injuries (TBIs) are among the most serious injuries covered under NSW's Compulsory Third Party (CTP) scheme. SIRA (State Insurance Regulatory Authority) administers claims under the Motor Accident Injuries Act 2017, which outlines how injuries are assessed and what benefits are available. If you've suffered a TBI in a motor vehicle accident in Bathurst, understanding SIRA's evaluation process is critical to securing support.

SIRA determines whether a TBI meets the 'threshold injury' criteria outlined in the Motor Accident Guidelines. This involves assessing clinical evidence, such as medical imaging, neurological tests, and a doctor's diagnosis. A TBI is classified as a threshold injury if it results in a whole person impairment (WPI) of 10% or more, or requires treatment and care. This distinction affects whether you qualify for statutory benefits like weekly income payments or treatment coverage.

Types of Damages and Benefits for Traumatic Brain Injuries

Under the CTP scheme, TBIs are treated as threshold injuries, meaning they fall under the statutory benefits framework rather than common law damages. This means:

  • Statutory benefits include weekly income payments, treatment and care benefits, and lump sum compensation for permanent impairment.
  • Common law damages are not available unless the injury exceeds the threshold and the claimant can prove fault, which is rare in CTP claims.

If your TBI results in a WPI of 10% or more, you may be eligible for a lump sum payment based on the injury's severity. SIRA uses the Motor Accident Guidelines to calculate this, which considers factors like the nature of the injury, long-term effects, and impact on daily life.

Practical Steps for Claimants in Bathurst

To pursue a TBI claim in Bathurst, take these steps:

  1. Seek immediate medical attention to document the injury. Ensure your doctor records neurological symptoms, imaging results, and any changes in cognitive function.
  2. Preserve evidence of the accident, including police reports, witness statements, and photos of the scene.
  3. Notify SIRA within 52 weeks of the accident to claim statutory benefits. Delays beyond this period may reduce or eliminate certain entitlements.
  4. Keep records of income and expenses related to the injury, such as lost wages, medical bills, and transportation costs.

SIRA may request additional documentation to confirm the injury meets the threshold. If your claim is disputed, you can appeal through the NSW Civil and Administrative Tribunal (NCAT) or seek independent medical opinions.

Time Limits and Dispute Resolution

The CTP scheme imposes strict time limits. For example, weekly income payments are generally available only for 52 weeks after the accident, unless the injury is classified as a 'permanent impairment' under the Motor Accident Guidelines. If your TBI results in long-term or permanent effects, you may qualify for extended benefits, but this requires ongoing medical evidence.

Disputes over injury classification are common. SIRA may challenge whether a TBI meets the threshold, especially if the injury is minor or the impairment is disputed. In such cases, consulting a solicitor specialising in CTP claims can help navigate the process.

When to Seek Legal Advice

While SIRA handles most claims, complex cases, such as those involving long-term cognitive decline, multiple injuries, or disputes over impairment ratings, often require legal assistance. A solicitor can help:

  • Challenge SIRA's decision to deny or limit benefits.
  • Navigate the process of obtaining independent medical assessments.
  • Ensure all statutory requirements are met to avoid claim dismissal.

If your TBI claim is denied or you're unsure about your entitlements, seek advice from a solicitor with experience in NSW CTP matters.
