MAC Act Legacy Claims in NSW: Key Changes After 2017 Reforms

The 2017 NSW CTP reforms replaced the MACA with the MAIA, altering how legacy claims are processed. Legacy claims under MACA retain older rules, including broader eligibility for benefits and longer time limits. Claimants must gather evidence, notify insurers, and seek legal advice if disputes arise. Time limits and injury thresholds remain critical for both schemes.

Current as at 20 October 2026

The 2017 reforms to NSW motor accident compensation laws replaced the Motor Accident Claims Act 1999 (MACA) with the Motor Accident Injuries Act 2017 (MAIA). This shift significantly altered how legacy claims under the old MACA are processed. If your accident occurred before 1 December 2017, your claim may still fall under the MACA, but the new MAIA rules now govern claims for accidents after that date. Understanding these changes is critical for claimants seeking compensation.

How the 2017 Reforms Changed Legacy Claims

The MAIA introduced a new framework for CTP claims, including stricter rules on injury thresholds, benefits, and time limits. For legacy MACA claims, the key differences include:

  • Eligibility for benefits: Under MACA, claimants could receive weekly payments for any injury, regardless of severity. The MAIA now limits weekly benefits to 'threshold injuries', injuries meeting specific medical criteria, such as soft tissue injuries with neurological signs.
  • Time limits: The MAIA imposes a 52-week limit on weekly payments for threshold injuries. Legacy MACA claims are not subject to this cap, but claimants must still meet the original MACA’s requirements.
  • Dispute resolution: The MAIA introduced the NSW Civil and Administrative Tribunal (NCAT) to handle disputes, whereas MACA claims were typically resolved through the courts.

Practical Steps for Pursuing Legacy Claims

If your claim falls under the MACA, you must still meet the original scheme’s criteria. Key steps include:

  1. Gather evidence: Collect medical records, accident reports, and witness statements. SIRA’s guidelines emphasize the importance of documenting injuries and treatment.
  1. Notify the insurer: Inform the at-fault driver’s CTP insurer within 90 days of the accident. Delays may jeopardize your claim.
  1. Seek medical assessment: A medical practitioner must confirm your injury meets the MACA’s definition of a 'personal injury.' This is crucial for determining entitlements.
  1. Monitor time limits: While the MAIA’s 52-week rule does not apply to legacy claims, the original MACA had a 5-year time limit for filing claims. Ensure your claim is submitted before this deadline.

When to Seek Legal Advice

Disputes over injury severity, benefit calculations, or claim eligibility are common. For example, if your claim is denied due to a dispute over whether your injury meets the threshold, you may need legal assistance to challenge the decision. SIRA provides resources to help claimants navigate these issues, but complex cases often require a solicitor.

Example: A Legacy Claim Under MACA

Consider a claimant injured in a 2016 car accident. Under MACA, they could receive weekly payments for any injury, even if it was minor. However, under the MAIA, a similar injury today would only qualify for benefits if it met the threshold criteria. This distinction highlights how the 2017 reforms changed the compensation landscape.

If your claim falls under the MACA, ensure you meet the original scheme’s requirements. Time limits and evidence thresholds remain critical. For personalized guidance, complete the quick, no obligation enquiry form to request contact about your circumstances.
