MAC Act Legacy Claims: Injury Documentation Checklist for NSW Residents

This article explains the injury documentation required for legacy motor accident claims under the Motor Accidents Compensation Act 1999 in NSW. It outlines the medical, financial and procedural evidence that supports a claim, how SIRA assesses it, and common errors to avoid. Time limits and the importance of independent advice are also addressed.

Understanding MAC Act Legacy Claims in NSW

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 your motor accident occurred before 1 December 2017, you may be governed by the Motor Accidents Compensation Act 1999 (MACA), which remains in effect for claims arising from those events. This framework differs significantly from the current Motor Accident Injuries Act 2017 (MAIA), particularly in how injury documentation is assessed and what benefits may be available. For claimants under the MACA, the type and quality of medical evidence required to support a claim is critical, as it directly affects eligibility for compensation, including damages for pain and suffering, loss of income, and future care needs.

What Injury Documentation Is Required?

To support a claim under the MACA, you must provide clear and contemporaneous medical evidence that establishes the nature, extent, and duration of your injuries. This includes:

  • A detailed medical report from your treating medical practitioner, including diagnosis, treatment provided, and prognosis.
  • A record of all medical appointments, treatments, and diagnostic tests (such as MRI, CT scans, or X-rays) related to the accident.
  • Evidence of ongoing symptoms, including any functional limitations or inability to perform daily activities.
  • A statement from your employer, if you have been unable to work, confirming your absence and the impact on your duties.
  • Photographs of visible injuries, if applicable, taken shortly after the accident.
  • A written account of the accident from you, your witness, or a police report, if available.

SIRA (the State Insurance Regulatory Authority) uses this documentation to assess whether your injuries meet the criteria for compensation under the MACA, including whether they are permanent, disabling, or have resulted in significant financial loss.

How SIRA Assesses Injury Documentation

SIRA evaluates injury documentation under the MACA framework using specific criteria. Unlike the MAIA, which uses a threshold injury system, the MACA allows for claims based on the severity and permanency of injury, regardless of whether a threshold is met. However, the burden of proof lies with the claimant to demonstrate that:

  • The injury was caused by the motor accident.
  • The injury has resulted in a permanent impairment or long-term functional loss.
  • The injury has caused financial loss, including loss of earnings or future care needs.

SIRA may request independent medical assessments to verify the extent of your injury. These assessments are conducted by qualified medical practitioners and may include neurological, orthopaedic, or psychological evaluations. It is essential that your medical records are complete, consistent, and supported by objective findings.

Common Pitfalls to Avoid

Many MACA legacy claims are delayed or denied due to preventable documentation issues. Common pitfalls include:

  • Delaying the submission of medical records, which can weaken the link between the accident and injury.
  • Failing to obtain a formal medical report that details the diagnosis, treatment, and prognosis.
  • Not preserving records of ongoing treatment, particularly if symptoms persist beyond initial recovery.
  • Submitting incomplete or inconsistent statements from medical practitioners.
  • Not providing evidence of financial loss, such as pay slips, tax returns, or employer letters.

These issues can significantly impact your claim. For example, a claimant who sustained a spinal injury in a 2016 car crash was initially denied compensation because their medical records did not include a formal assessment of permanent impairment. After obtaining a specialist report and additional diagnostic imaging, the claim was reinstated and awarded.

Time Limits and Procedural Requirements

Under the MACA, you must make a claim within three years of the accident date. This time limit is strict and cannot be extended unless exceptional circumstances apply. You must also notify your insurer and SIRA as soon as possible after the accident to preserve your rights.

If you are disputing a decision made by SIRA or your insurer, you may apply to the NSW Civil and Administrative Tribunal (NCAT) for a review. To do so, you must submit your application within 28 days of receiving the decision. Failure to meet this deadline may result in your claim being barred.

When to Seek Independent Advice

Given the complexity of MACA legacy claims and the importance of accurate documentation, it is advisable to seek independent legal advice if:

  • You have sustained a serious or permanent injury.
  • Your claim has been denied or partially accepted.
  • You are unsure whether your injury qualifies for compensation under the MACA.
  • You are seeking damages for pain and suffering or future care needs.

Legal advice can help you understand your rights, ensure your documentation meets SIRA’s standards, and assist with the preparation of submissions or tribunal applications.
