(a) at any time after a lump sum is paid to an employee under section 30 in respect of an injury, the injury results in the employee being incapacitated for work to the extent that the employee is not able to engage in suitable employment; and
(b) the incapacity is likely to continue indefinitely;
Comcare is liable to pay compensation to the employee under this section during the period of the incapacity.
(2) The amount of compensation is an amount per week equal to the amount per week that would, but for the payment of the lump sum, have been payable to the employee under section 19, 20, 21 or 21A, as the case may be, in respect of the incapacity, less the amount per week that was redeemed at the date of the determination under section 30.
