How SIRA Determines if a Pre-existing Injury is Aggravated by a Motor Accident

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

In New South Wales, the State Insurance Regulatory Authority (SIRA) oversees claims under the Motor Accident Injuries Act 2017. If you’ve suffered a motor accident that worsens a pre-existing injury, SIRA assesses whether the accident caused a deterioration in your condition. This process determines your eligibility for compensation.

SIRA defines 'aggravation' as a worsening of a pre-existing injury caused by the motor accident. For example, if you had a pre-existing back injury and the accident caused additional damage, SIRA will evaluate if the accident directly contributed to the worsening. Key factors include medical evidence showing a direct link between the accident and the injury’s deterioration.

Practical Steps and Evidence for Pre-existing Injury Claims

To support a claim of pre-existing injury aggravation, you must provide:

  • Medical records detailing the original injury and its progression
  • Accident reports showing how the collision occurred
  • Expert medical opinions confirming the aggravation
  • Witness statements or other evidence linking the accident to the injury’s worsening

In Bega, claimants should ensure all documentation clearly establishes the pre-existing condition and how the accident caused a direct deterioration. SIRA may require a specialist report to assess the link between the accident and the aggravation.

Time Limits and Dispute Resolution

Claims must be submitted within the statutory time limits outlined in the Motor Accident Injuries Act 2017. If the injury is classified as a 'threshold injury' (a minor soft tissue injury), benefits may be limited after 52 weeks. However, if the aggravation results in a more severe injury, compensation may continue beyond this period.

If SIRA disputes your claim, you may request a review or seek independent medical assessment. It’s critical to act promptly, as delays can affect the assessment of aggravation and eligibility for benefits.

When to Seek Legal Advice

Understanding whether your pre-existing injury is aggravated by a motor accident requires careful analysis of medical and accident evidence. In Bega, claimants should consult a legal professional if:

  • The injury’s aggravation is disputed by SIRA
  • You’re unsure how to document the link between the accident and the injury
  • You need assistance navigating the 52-week statutory benefit period

Legal experts can help ensure all evidence meets SIRA’s standards and that your claim accurately reflects the impact of the accident on your pre-existing condition.
