Pre-existing Injury Aggravation Checklist for CTP Claims on the Central Coast

This article explains how to document pre-existing injuries aggravated by motor accidents on the Central Coast under NSW CTP rules. It outlines required evidence, SIRA's assessment process, and common pitfalls to avoid, while highlighting when to seek legal advice.

Current as at 15 October 2026

If you've been in a motor accident on the Central Coast and your existing injury worsened, you may be eligible for compensation under NSW's Compulsory Third Party (CTP) scheme. This article explains what documentation is needed to support your claim, how SIRA evaluates pre-existing injury aggravation cases, and common mistakes to avoid. The information applies to accidents occurring on NSW roads, including the Central Coast, and is based on the Motor Accident Injuries Act 2017 and SIRA guidelines.

Proving Pre-existing Injury Aggravation

To claim compensation for an aggravated pre-existing injury, you must demonstrate that the motor accident worsened your condition. Key evidence includes:

  • Medical records showing your injury existed before the accident (e.g., diagnosed in the past 12 months)
  • Pre-accident medical reports confirming your condition was stable prior to the crash
  • Post-accident medical evidence showing deterioration, such as worsened pain, reduced mobility, or new symptoms
  • Expert opinion from a medical practitioner linking the accident to the aggravation

SIRA requires clear documentation to distinguish between pre-existing injuries and new injuries caused by the accident. For example, if you had a pre-existing back injury and the accident caused a herniated disc, you may be eligible for compensation for the worsened condition.

How SIRA Assesses Aggravated Injuries

SIRA evaluates claims by comparing your condition before and after the accident. Key considerations include:

  • Medical evidence showing a direct link between the accident and the aggravation
  • Clinical signs of worsened injury, such as increased pain, loss of function, or new neurological symptoms
  • Impact on daily life - how the aggravation affects your ability to work, travel, or perform routine tasks
  • Medical opinion that the aggravation would not have occurred without the accident

In some cases, SIRA may require a second medical opinion to confirm the aggravation. For instance, if a pre-existing knee injury worsened after a collision, a specialist might need to assess whether the accident caused additional damage.

Practical Steps for Central Coast Claimants

  1. Seek immediate medical attention after the accident, even if you feel fine. Document all treatments and keep records of all medical appointments.
  2. Notify your doctor about the accident and its potential impact on your existing condition.
  3. Gather accident details - include police reports, witness statements, and photographs of the scene.
  4. Request a pre-accident medical summary from your doctor to establish the condition before the crash.
  5. Submit all evidence to SIRA within 52 weeks of the accident, as weekly benefits may stop after this period if only threshold injuries are involved.

Common Pitfalls to Avoid

  • Failing to document pre-existing injuries - Without proof of your condition before the accident, your claim may be rejected.
  • Not linking the accident to the aggravation - SIRA requires clear evidence that the crash worsened your injury, not just caused a new one.
  • Delaying medical treatment - Delayed care can make it harder to prove the aggravation.
  • Not seeking specialist input - General practitioners may not be able to establish the link between the accident and the worsened condition.

Time Limits and Dispute Options

You have 52 weeks from the accident date to claim weekly benefits for threshold injuries. If your claim involves a serious injury, you may have longer to pursue compensation, but time limits apply. If SIRA disputes your claim, you can:

  • Request a review by submitting additional evidence
  • Seek independent medical opinion to challenge SIRA's assessment
  • Consult a legal professional if you need help navigating the process

When to Seek Legal Advice

Speak to a solicitor if:

  • You're unsure whether your injury qualifies as aggravated
  • You've been denied a claim and want to challenge the decision
  • You need help gathering medical evidence
  • You're concerned about time limits or dispute options

Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
