Time Limits for Whiplash Claims Under NSW CTP Law

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).

If you've suffered a whiplash injury in a motor accident in New South Wales, you may be wondering how long you have to claim compensation. Under the NSW Compulsory Third Party (CTP) scheme, there are strict time limits for making a claim. This article explains the key rules, how SIRA handles whiplash claims, and practical steps to take.

Key Time Limits for CTP Claims

The Motor Accident Injuries Act 2017 sets strict deadlines for CTP claims. Generally, you must notify the at-fault driver’s insurer within 28 days of the accident. If you fail to notify them on time, you may lose your right to claim. This applies even if you haven’t yet sought medical treatment.

For soft-tissue injuries like whiplash, the 52-week rule applies. If your injury is classified as a 'threshold injury' under the Motor Accident Guidelines, you can claim weekly benefits and treatment for up to 52 weeks. After this period, benefits are typically limited unless you have a whole-person impairment rating of 10% or more.

How SIRA Handles Whiplash Claims

SIRA (State Insurance Regulatory Authority) manages CTP claims in NSW. For whiplash injuries, SIRA assesses whether the injury meets the 'threshold injury' definition. This includes soft-tissue neck injuries with neurological signs, such as tingling or numbness. If your injury falls within this category, you may be eligible for treatment and income support.

SIRA also considers whether your injury requires 'treatment and care' benefits. This includes physiotherapy, medical consultations, and other therapies. You must provide medical evidence to support your claim, such as a GP report or specialist opinion.

Practical Steps for Claiming Whiplash Compensation

To make a successful claim, take the following steps:

  • Seek medical attention immediately. Document all treatments, as medical records are critical for proving your injury.
  • Notify the at-fault driver’s insurer within 28 days. Delaying notification may result in your claim being rejected.
  • Keep records of all accident-related details. This includes police reports, witness statements, and photographs of the scene.
  • Submit a claim form to SIRA. You can apply online via the SIRA website or through an approved claims agent.

When to Seek Legal Advice

If your claim is denied or you’re unsure about your rights, seek legal advice. A solicitor can help you understand whether your injury qualifies for additional compensation beyond the standard CTP benefits. This is particularly important if your injury results in long-term disability or requires ongoing care.

Example Scenario

Consider a driver who was in a low-speed collision and later diagnosed with a soft-tissue neck injury. Under the 52-week rule, they can claim weekly benefits for 52 weeks. If their injury worsens and they receive a 15% whole-person impairment rating, they may be eligible for additional compensation. However, if their injury is classified as a 'threshold injury' only, benefits stop after 52 weeks.

Next Steps

CTP entitlements depend on the accident date, injury type, and claim history. To request contact about your circumstances, complete the quick, no obligation enquiry form. Every claim depends on its own facts.
