Eligibility to receive incapacity payments is determined by provisions of the Act in place at the date of the (original) injury. The calculation of the amount payable is however determined by provisions of the Act in place during the period of incapacity.
In practice, claims for periods of incapacity predating 1 December 1988 are now very rare. Most payments for 'old Act' injuries now relate to incapacity for work which occurred since December 1988, and are thus calculated under SRCA provisions.
