Pre-existing Injury Aggravation in NSW CTP Claims: Early Steps for Illawarra and South Coast Road Users

In NSW, a pre-existing injury worsened by a motor accident may qualify for CTP compensation. Early steps include documenting the existing condition, reporting the accident to SIRA within 52 weeks, and seeking medical confirmation of aggravation. Claims must demonstrate a clear link between the new accident and the worsened injury.

How NSW CTP Law Handles Pre-existing Injuries

In New South Wales, a pre-existing injury aggravated by a new motor accident may still qualify for compensation under the Compulsory Third Party (CTP) scheme. The Motor Accident Injuries Act 2017 (MAIA) and SIRA guidelines state that the new accident must have worsened an existing condition, not merely triggered a new injury. For example, if a person with a pre-existing back injury experiences a car accident that exacerbates their condition, they may be eligible for benefits. However, the claim must demonstrate a clear link between the new accident and the worsened injury.

Early Steps for Injured Road Users

  1. Document the Pre-existing Condition: Obtain medical records from before the accident showing the existing injury. This includes diagnosis dates, treatment history, and any prior claims.
  1. Record the New Accident: Gather evidence such as police reports, witness statements, and photographs of the scene. SIRA requires a detailed account of how the accident occurred.
  1. Notify SIRA Immediately: Under the MAIA, claims must be reported within 52 weeks of the accident. Delaying could jeopardize benefits for pre-existing injuries worsened by the new incident.
  1. Seek Medical Attention: A doctor must confirm that the new accident aggravated the existing condition. This is critical for SIRA to assess the claim.

SIRA’s Process for Pre-existing Injury Claims

SIRA evaluates claims by comparing the pre-existing injury’s condition before and after the new accident. If the aggravation is significant, benefits such as weekly income payments or treatment costs may apply. However, if the new accident only caused a separate injury, the pre-existing condition may not qualify. For instance, a person with a pre-existing knee injury who sustains a new ankle injury in a crash may not be eligible for CTP benefits related to the knee.

Time Limits and Dispute Resolution

Claims must be submitted within 52 weeks of the accident. If the pre-existing injury worsened after this period, SIRA may refuse the claim. Disputes over aggravation can be resolved by the NSW Civil and Administrative Tribunal (NCAT), which interprets the MAIA’s provisions on threshold injuries and aggravation.

When to Seek Legal Advice

Complex cases, such as overlapping injuries or disputes over aggravation, often require legal assistance. A solicitor can help navigate SIRA’s process, ensure all evidence is submitted, and challenge decisions that unfairly dismiss a claim.

Example Scenario

A cyclist with a pre-existing wrist injury (diagnosed two years prior) is involved in a collision where their wrist condition worsens. They must prove the new accident caused the aggravation, not a separate injury. Medical records showing pre- and post-accident symptoms are essential.
