How NSW CTP Law Handles Aggravated Pre-existing Injuries

If a motor accident worsens a pre-existing injury, injured people in NSW may still be eligible for compensation under the Compulsory Third Party (CTP) scheme. The key question is whether the aggravation of your existing condition qualifies as a 'threshold injury' under the Motor Accident Injuries Act 2017. SIRA (State Insurance Regulatory Authority) assesses claims by determining if the accident caused a new or worsened injury that meets the legal definition of a 'threshold injury', which includes conditions like whiplash, soft tissue injuries, or spinal nerve-root damage.

Proving Aggravation of a Pre-existing Injury

To claim compensation, you must show:

  • Medical evidence of your pre-existing condition (e.g., past injury records, specialist reports)
  • Proof that the motor accident aggravated the injury (e.g., worsened pain, new symptoms, or reduced function)
  • A medical opinion linking the aggravation to the accident

SIRA requires clear documentation showing the accident caused a 'new injury' or worsened an existing one beyond its original state. For example, if a car crash aggravated a pre-existing back injury, you must demonstrate the accident caused additional harm.

What You Can Claim Under the CTP Scheme

Under the CTP scheme, you may claim:

  • Weekly income benefits if the aggravation prevents you from working
  • Treatment and care benefits for medical expenses related to the aggravation
  • Compensation for pain and suffering if the injury meets the 'whole person impairment' threshold

However, if your injury is classified as a 'threshold injury' (not meeting the whole person impairment standard), benefits may stop after 52 weeks. This applies only if the aggravation was the sole cause of your injury.

Practical Steps for Injured People in Auburn

  1. Seek immediate medical attention to document the aggravation of your injury
  2. Keep detailed records of your pre-existing condition, including past medical reports and specialist opinions
  3. Notify your insurer about the aggravation and request a review of your claim
  4. Gather evidence like accident reports, witness statements, and photographs of the scene
  5. Consult a solicitor if your claim is disputed or if you need help navigating SIRA's assessment process

Time Limits and Dispute Resolution

You have 28 days to notify your insurer of the aggravation after the accident. If your claim is rejected, you may need to escalate the matter to SIRA or seek legal advice. Remember, the 52-week limit for benefits applies only if your injury is a 'threshold injury' and the aggravation was the sole cause.

When to Seek Legal Advice

Speak to a solicitor if:

  • You're unsure whether your injury qualifies as aggravated
  • Your claim has been rejected
  • You need help gathering evidence
  • You want to understand your options for compensation

Legal professionals can help you navigate SIRA's assessment process and ensure your claim reflects the full impact of the aggravation.
