In determining whether attendant care services are reasonably required for a person, the Commission must have regard to the following matters:
(a) the nature of the person's injury or disease;
(b) the degree to which that injury or disease impairs the person's ability to provide for his or her personal care;
(c) the extent to which any medical service or nursing care received by the person provides for his or her essential and regular personal care;
(d) the extent to which the attendant care services are necessary to meet any reasonable wish by the person to live outside an institution;
(e) the extent to which attendant care services are necessary to enable the person to undertake or continue defence service or any other work;
(f) any assessment made in relation to the rehabilitation of the person;
(g) the extent to which a relative of the person might reasonably be expected to provide attendant care services;
(h) any other matter that the Commission considers relevant.
