Seek legal advice to understand how the reforms impact your specific case.

Traumatic brain injury claims under NSW CTP reforms

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 now treated as threshold injuries under the NSW Compulsory Third Party (CTP) scheme following the 2017 reforms. This means claimants on the Central Coast must meet specific criteria to access statutory benefits, replacing the previous common law damages model. The reforms introduced by the Motor Accident Injuries Act 2017 shifted focus to medical evidence and statutory limits, significantly altering how TBIs are assessed and compensated.

Key changes to TBI claims post-2017

The 2017 reforms replaced common law claims with statutory benefits under the Motor Accident Injuries Act 2017. For traumatic brain injuries, this means:

  • Threshold injury definition: TBIs are classified as threshold injuries if they meet the spinal nerve-root criteria in the Motor Accident Guidelines. This includes neurological signs beyond radiculopathy.
  • 52-week statutory benefit period: Weekly income payments and treatment benefits are generally limited to 52 weeks unless the injury results in a whole person impairment (WPI) of 10% or more.
  • SIRA's role: The State Insurance Regulatory Authority (SIRA) now oversees claims, applying strict guidelines to assess both threshold injuries and WPI claims.

Previously, claimants could pursue common law damages for TBIs, but the reforms prioritized statutory benefits. This shift has reduced the scope for damages claims unless the injury exceeds the threshold.

Practical steps for TBI claims on the Central Coast

To pursue a traumatic brain injury claim under the current CTP scheme, claimants should:

  1. Seek immediate medical attention: Document the injury with a medical practitioner, as SIRA requires clinical evidence to confirm threshold injury status.
  2. Preserve accident details: Gather evidence such as police reports, witness statements, and photographs to support the claim.
  3. Notify the at-fault driver's insurer: Under the CTP scheme, claims must be submitted to the insurer of the negligent driver, not the claimant's own insurance.
  4. Follow SIRA's claims process: Use the online portal at sira.nsw.gov.au to submit claims and track progress.

Claimants should also be aware of the 52-week statutory benefit period. If the injury does not meet the WPI threshold, benefits will generally stop after 52 weeks, regardless of ongoing symptoms.

Time limits and dispute resolution

The 2017 reforms introduced strict time limits for CTP claims. Most claims must be submitted within 52 weeks of the accident, though exceptions exist for complex cases. Delays can jeopardize access to benefits, so prompt action is essential.

Disputes over TBI claims are resolved by SIRA, which applies the Motor Accident Guidelines to assess whether the injury meets the threshold. Claimants should seek legal advice if their claim is rejected or if they believe the assessment is incorrect.

Example: How the 52-week rule affects TBI claims

Consider a claimant who suffered a TBI in a car accident on the Central Coast. Under the 2017 reforms, they would receive weekly income payments and treatment benefits for 52 weeks. If their injury does not meet the WPI threshold, benefits stop, even if symptoms persist. This contrasts with the previous common law model, where claimants could pursue damages for life.

When to seek legal advice

The reforms have narrowed the scope of compensation for TBIs, making it critical to understand the distinction between threshold injuries and WPI claims. Legal advice is recommended to:

  • Confirm whether the injury meets the threshold or WPI criteria.
  • Navigate SIRA's claims process.
  • Challenge a rejected claim or dispute a benefit calculation.
