Australia is a federation; personal-injury law is overwhelmingly state law. Each state and territory operates its own Civil Liability Act and its own CTP insurance scheme for motor injury. The shared features are a statutory threshold below which general damages are not recoverable, a statutory cap above which they cannot be awarded, and an impairment-percentage assessment that sits at the centre of the assessment.
CTP schemes, Motor Accidents Injuries Act 2017 (NSW) administered by SIRA and icare; Transport Accident Act 1986 (Vic) administered by the TAC; Motor Accident Insurance Act 1994 (Qld) administered by the MAIC; analogues in WA, SA, Tas, ACT, and NT, each have different thresholds, benefit structures, and dispute-resolution paths. NSW and Victoria operate hybrid no-fault / common-law schemes; SA and ACT are pure CTP fault-based.
For non-CTP personal injury (workplace, premises, public liability), the relevant state Civil Liability Act and (in NSW) the Workers Compensation Act 1987 control. Limitation periods are generally three years from discoverability.
