The Motor Accidents Authority (MAA) is a statutory corporation that regulates the NSW Motor Accidents Scheme, that is, the Compulsory Third Party (CTP) personal injury insurance scheme for motor vehicles registered in New South Wales .
The MAA was established by the Motor Accidents Act 1988 on 10 March 1989 and continues to be constituted under the Motor Accidents Compensation Act 1999.
The scheme was amended by the Motor Accidents Compensation Act 1999 which commenced on 5 October 1999 . The purpose of the amendment was to lower the price of green slip premiums for the majority of NSW motorists, reduce the level of litigation in resolving claims and ensure that medical treatment for injured people occurs promptly and cost-effectively.
