Motor Accidents Compensation Act 1999, Injury Documentation Checklist (Greater Sydney)

Current as at 19 June 2026

If you were injured in a motor accident in Greater Sydney before 1 December 2017, understanding the required documentation for a CTP claim under the Motor Accidents Compensation Act 1999 (MACA) is essential. This guide explains what medical records, accident details and other evidence are typically needed to support a claim, how SIRA assesses documentation and common mistakes to avoid. Proper records can significantly impact the outcome of your claim.

What Medical Documents Are Required for MACA Claims?

Under the MACA, injured claimants must provide medical evidence to support their claim. Key documents include:

  • Medical reports from doctors or specialists confirming the injury, its cause and severity
  • Diagnostic imaging (X-rays, MRIs, CT scans) showing injuries
  • Treatment records detailing medical interventions, medications and recovery progress
  • Notes from physiotherapists or occupational therapists if rehabilitation was needed
  • Statements from treating medical practitioners about the injury's impact on daily life

SIRA requires these documents to assess whether the injury meets the MACA's 'threshold injury' definition. A threshold injury must involve a spinal nerve-root injury producing neurological signs, or radiculopathy with specific clinical signs as outlined in the Motor Accident Guidelines.

How SIRA Uses Injury Documentation

SIRA evaluates claims based on the evidence provided. For example, if you suffered a soft tissue injury (like a whiplash), your medical records must show:

  • A diagnosis of a soft tissue injury
  • Evidence of neurological signs beyond radiculopathy
  • A connection between the injury and the accident

In one case, a claimant's records showed persistent neck pain and reduced range of motion after a collision. SIRA accepted the injury as a threshold injury because the medical evidence met the required criteria. Without proper documentation, claims may be denied or delayed.

Common Documentation Errors to Avoid

Many claimants make mistakes that weaken their case. Avoid:

  • Submitting incomplete or delayed medical records
  • Failing to document the accident's details (date, time, location, vehicle details)
  • Not keeping records of lost income or additional expenses
  • Providing inconsistent statements about the injury's onset and severity

For instance, if you didn't report the accident to your doctor within a reasonable time, SIRA may question the injury's connection to the incident. Always keep all records organised and submit them promptly.

Time Limits and Dispute Options

You have 52 weeks from the accident date to claim benefits for 'only injuries' under the MACA. After this period, weekly payments and treatment benefits generally stop unless the injury is classified as a 'whole person impairment' (WPI) of 10% or more. If your claim is disputed, you can:

  • Request a review from SIRA
  • Seek independent medical opinions
  • Consult a legal professional for dispute resolution

When to Seek Legal Advice

If you're unsure whether your injury meets the MACA's criteria, or if your claim has been rejected, it's wise to seek legal advice. A solicitor can help you:

  • Gather and organise required documentation
  • Challenge a disputed claim
  • Understand your options under the MACA
