(1) The Commission may determine, in writing, a scheme, called the Motor Vehicle Compensation Scheme (the MVCS ), under which the Commonwealth is liable to provide compensation of a kind mentioned in subsection (2) to a person in circumstances identified in the MVCS if:
(a) the person has suffered an impairment as a result of a service injury or disease for which the Commission has accepted liability; and
(b) because of that impairment, the person has a need for compensation of that kind; and
(c) a claim for compensation in respect of the person has been made under section 319.
(2) The kinds of compensation are:
(a) modifying a motor vehicle for a person; and
(b) maintaining or repairing modifications to a motor vehicle; and
(c) subsidising the purchase of a motor vehicle by a person; and
(d) purchasing a motor vehicle for a person; and
(e) other kinds of compensation relating to motor vehicles specified in the MVCS.
(3) The Commission may, from time to time, repeal or amend the MVCS in writing.
(4) The MVCS, and any repeal or amendment of the MVCS, is a legislative instrument.
(5) The Commonwealth is only liable to pay compensation under the MVCS in respect of an aggravated injury or disease if it is because of the aggravation or material contribution (whether wholly or partly) that the person suffered the impairment.
