MAI Act Transitional Claims: Early Steps for Injured Road Users in Western Sydney

This article explains the early steps for injured road users in Western Sydney to pursue transitional claims under the MAI Act, covering documentation, SIRA guidance, and key considerations for claims spanning pre- and post-2017 CTP law changes.

Current as at 15 October 2026

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 were injured in a motor vehicle accident in Western Sydney and your claim spans the transition from the old Motor Accidents Compensation Act 1999 (MACA) to the current Motor Accident Injuries Act 2017 (MAI Act), you need to understand how transitional claims work. This article explains the essential steps to take immediately after an accident, how to apply SIRA guidance to your situation, and what evidence to gather. Transitional claims are unique because they involve both pre- and post-2017 CTP rules, requiring careful attention to time limits and legal definitions.

Understanding Transitional Claims Under the MAI Act

Transitional claims apply to accidents occurring before 1 December 2017, where the injured person is still seeking compensation under the old MACA scheme. However, the MAI Act introduced significant changes, including a shift from a no-fault system to one where fault may affect entitlements. For claims that began under MACA but continue after 2017, the MAI Act’s rules apply, including the 52-week limit for certain benefits.

SIRA (State Insurance Regulatory Authority) provides authoritative guidance on transitional claims. According to SIRA, transitional claims must be processed under the MAI Act’s framework, even if the injury occurred before 2017. This means that while some benefits under MACA may still apply, others are replaced by the MAI Act’s statutory benefits, such as weekly payments and treatment and care benefits.

Practical Steps for Injured Road Users in Western Sydney

If you were injured in a motor vehicle accident in Western Sydney and your claim crosses the 2017 transition date, take these steps immediately:

  • Seek medical attention - Document all injuries and treatment, as medical records are critical for determining the nature and severity of your injury.
  • Preserve accident details - Gather evidence such as police reports, witness statements, and photographs of the scene. The location of the accident (e.g., a car park, road, or intersection) may affect how your claim is assessed under both schemes.
  • Notify the relevant insurer - If the accident involved a registered motor vehicle, contact the at-fault driver’s insurer. Under the MAI Act, claims are typically handled by the insurer of the negligent driver, not the injured person’s own insurance.
  • Review SIRA’s transitional claim guidance - SIRA’s website provides specific instructions for transitional claims, including how to apply for statutory benefits and what evidence to submit. This includes details on how to calculate weekly payments and whether your injury meets the threshold for statutory benefits.

Key Documentation for Transitional Claims

To support your transitional claim, you’ll need to provide:

  • Medical records - These must show the injury’s nature, treatment received, and how it relates to the accident. SIRA emphasizes that injuries must be assessed under the MAI Act’s threshold injury criteria, which includes spinal nerve-root injuries producing neurological signs.
  • Accident reports - Police reports or incident reports from the scene are essential to establish the circumstances of the accident.
  • Witness statements - Statements from witnesses can help corroborate your account of the incident.
  • Income and employment records - If you’re claiming weekly payments, you’ll need to provide evidence of your pre-accident income to calculate the benefit amount.
  • Correspondence with insurers - Keep copies of all communications with insurers, as they may affect how your claim is processed under the MAI Act.

Time Limits and Dispute Resolution

Under the MAI Act, claims must generally be submitted within 52 weeks of the accident, unless an extension is granted. For transitional claims, the 52-week limit applies to statutory benefits, but common law damages claims may have different time limits. If your claim involves both statutory benefits and damages, you must ensure you meet all deadlines.

If you disagree with how your claim is being assessed, you may need to seek independent legal advice. SIRA provides a complaints process, but complex transitional claims often require a solicitor to navigate the overlap between the old MACA and new MAI Act rules.

When to Seek Legal Advice

Transitional claims are complex because they involve two different legal frameworks. If your injury occurred before 2017 but your claim continues under the MAI Act, you should consult a solicitor to:

  • Determine whether your injury qualifies for statutory benefits under the MAI Act.
  • Understand how fault or contributory fault may affect your claim.
  • Ensure you meet all time limits for submitting claims.

Legal advice is particularly important if your claim involves disputes over the nature of your injury, the calculation of weekly payments, or the application of the 52-week limit.

Example: A Transitional Claim in Western Sydney

Consider a scenario where a pedestrian in Western Sydney was hit by a car on 1 January 2017. The injury was assessed as a soft-tissue injury under the old MACA scheme, but the claim continued under the MAI Act. The injured person would need to:

  1. Submit a claim for statutory benefits under the MAI Act.
  2. Provide medical evidence to show the injury meets the threshold for statutory benefits.
  3. Ensure the claim is submitted within 52 weeks of the accident.

This example highlights the need for careful documentation and understanding of how transitional claims work under both schemes.

Next Steps

If your claim involves the transition from MACA to the MAI Act, take action now to preserve your rights. Gather evidence, submit claims within time limits, and seek legal advice if disputes arise. Every claim depends on its own facts, and the rules for transitional claims can be complex. To request contact about your circumstances, complete the quick, no obligation enquiry form.
