Section 146 of DRCA [2] provides that the Chief of the Defence Force or the Military Rehabilitation and Compensation Commission (MRCC) is the rehabilitation authority (rather than the Commonwealth) for defence-related claims, as per the provisions of section 39 of the MRCA [3].
Subsection 146(3) of the DRCA [2] directs the rehabilitation authority to: "take all reasonable steps to provide the employee with suitable employment or to assist the employee to find such employment" in accordance with section 40 of DRCA. [2]
Section 62 of the MRCA [3] is identical in intent to section 40 of the DRCA [2] and defines that at the end phase of the vocational rehabilitation process: "The person's rehabilitation authority must take all reasonable steps to assist the person to find suitable civilian work."
