The Motor Accident Injuries Act 2017: How the NSW Statutory Benefits Scheme Works

If you have been injured in a motor accident in NSW, the legislation that governs your claim depends on when the accident happened.

For accidents occurring before 1 December 2017, claims fall under the Motor Accidents Compensation Act 1999. For accidents on or after that date, a separate scheme applies: the Motor Accident Injuries Act 2017.

The two Acts are not the same. The 2017 Act introduced a different structure for statutory benefits, different thresholds for accessing common law damages, and its own set of indexed amounts. Applying the wrong framework to the wrong claim is a meaningful error, and one that is not always immediately obvious.

Why the 2017 Act Was Introduced

The Motor Accident Injuries Act 2017 represented a significant reform to the NSW compulsory third party insurance scheme. It introduced a no-fault statutory benefits scheme for injured road users, providing income replacement and medical benefits regardless of who was at fault for the accident.

The intent was to ensure that injured parties received timely financial support in the period following an accident, without needing to establish fault before receiving assistance.

The Maximum Weekly Statutory Benefits Amount

One of the most important figures in the 2017 scheme is the maximum weekly statutory benefits amount under Section 3.9 of the Act.

As at 1 October 2025, this maximum was $5,116 per week.

This cap limits the amount of weekly income replacement benefits that can be paid under the statutory scheme, regardless of a claimant's actual pre-injury earnings. For higher-income earners, the cap may result in statutory benefits that fall well short of their actual pre-injury take-home pay.

This figure is indexed and updated periodically, meaning it changes over time. As with other indexed amounts in NSW personal injury legislation, applying the correct figure for the relevant period is important in any assessment of past benefits paid or future entitlements.

How Statutory Benefits Work in Practice

Under the 2017 Act, injured road users are entitled to receive weekly income support payments in the period following their accident, subject to the statutory cap and other eligibility conditions.

The income support is calculated by reference to the claimant's pre-injury weekly earnings, up to the maximum amount. Benefits are payable for defined periods, with different rules applying depending on whether the claimant is at fault and how severe their injury is.

Medical expenses and treatment costs can also be covered under the statutory benefits scheme, subject to specific conditions and approval processes.

Access to Common Law Damages

Not every person injured in a motor accident after 1 December 2017 is entitled to pursue a common law damages claim. The 2017 Act imposes thresholds that must be met before a claimant can access the full range of damages, including non-economic loss.

Understanding where a claimant sits in relation to these thresholds is an important early step in any post-2017 motor accident matter.

For claimants who do meet the threshold and pursue a common law claim, the maximum non-economic loss amount under Section 4.22 of the 2017 Act was $691,000 as at 1 October 2025, consistent with the figure under the older 1999 Act.

The Difference Between the Two Acts in Practice

For legal teams and forensic accountants working on motor accident matters, correctly identifying which Act applies is the starting point for everything that follows.

The weekly benefit cap, the structure of the income replacement calculation, the conditions for accessing common law damages, and the indexed amounts all differ between the two regimes. A damages assessment prepared under the wrong Act will apply the wrong caps and the wrong framework, producing an unreliable result.

At DB Forensic, we identify the correct legislative framework at the outset of each motor accident matter and apply the indexed amounts, benefit caps, and calculation methodology that are specific to that Act.
