Serious Injury Threshold, Evidence and Records to Keep (Auburn)

This article explains the evidentiary requirements for serious injuries under NSW CTP claims, focusing on what documentation to preserve in Auburn. It outlines the legal threshold, types of evidence needed, and when to seek legal advice to support your claim.

Current as at 19 August 2026

If you've suffered a serious injury in a motor accident in NSW, understanding the evidentiary requirements for CTP claims is critical. The NSW Motor Accident Injuries Act 2017 and SIRA guidelines define what constitutes a serious injury, and preserving the right evidence can determine whether you qualify for compensation. This article explains what documentation matters, how to manage records, and when to seek legal advice.

What is a serious injury under NSW CTP laws?

A serious injury under the CTP scheme is one that exceeds the 'threshold injury' definition in the Motor Accident Injuries Act 2017. Threshold injuries typically include soft tissue injuries like whiplash, sprains, or strains, but serious injuries involve more severe harm. Examples include:

  • Fractures or dislocations
  • Head injuries with neurological symptoms
  • Spinal injuries requiring medical intervention
  • Injuries causing long-term functional impairment

SIRA's guidelines specify that a serious injury must result in a whole person impairment rating of 10% or more, or meet specific clinical criteria like spinal nerve-root injuries with neurological signs. This distinction is crucial because it determines whether you qualify for ongoing benefits or damages.

What evidence is needed to prove a serious injury?

To support a serious injury claim, you must provide documented evidence of:

  • Medical records: Detailed reports from doctors, specialists, and physiotherapists showing the nature and severity of your injury. This includes imaging (X-rays, MRIs) and clinical notes.
  • Accident details: Police reports, witness statements, and photos of the scene. These help establish the circumstances of the accident.
  • Medical treatment records: Proof of ongoing care, such as therapy sessions, medication, or specialist consultations.
  • Income and employment records: Evidence of lost wages or reduced earning capacity, if applicable.
  • SIRA's injury assessment: A completed SIRA injury assessment form, which evaluates your injury against the threshold criteria.

For example, if you suffered a whiplash injury with neurological signs (like tingling or numbness), your doctor's notes must clearly document these symptoms to meet the threshold. This is because the spinal nerve-root qualification under the Motor Accident Guidelines requires specific clinical signs beyond radiculopathy.

How to document and retain evidence in Auburn?

In Auburn, as in all NSW locations, claimants should:

  1. Secure medical records immediately. Inform your doctor that your injury relates to a CTP claim, as this affects how records are managed.
  2. Preserve accident-related evidence. Store police reports, witness contact details, and photos in a secure location. Avoid altering or deleting digital copies.
  3. Track all correspondence. Keep copies of all communications with insurers, including emails, letters, and phone notes.
  4. a Maintain a timeline of events. Document when injuries occurred, treatments received, and any changes in your condition.

SIRA's guidelines emphasize that evidence must be 'sufficient to establish the injury' and 'support the claimant's entitlement to benefits'. This means fragmented or incomplete records may weaken your case.

Time limits and when to seek advice

The 52-week statutory benefit rule applies to threshold injuries, but serious injuries are not subject to this limit. However, time limits for certain claims may still apply. For example, you must notify your insurer within 14 days of the accident, and some benefits have specific deadlines.

If you're unsure whether your injury meets the threshold, or if your claim is disputed, seek legal advice. A solicitor can help you:

  • Navigate SIRA's assessment process
  • Challenge incorrect injury classifications
  • Ensure all evidence is properly preserved and submitted

Next steps

CTP claims involving serious injuries require careful documentation and understanding of the threshold criteria. If your injury involves long-term impairment, ongoing treatment, or significant impact on your daily life, you may be eligible for additional benefits. Always seek professional advice to ensure your claim is properly prepared.
