(1) The object of this Part is to establish a system that seeks to ensure that a worker who suffers a work injury—
(a) achieves the best practicable levels of physical and mental recovery; and
(b) returns to the worker's pre-injury work or, if that is not reasonably practicable, is in any event restored to the workforce and the community in a timely, safe and durable way.
(2) Without limiting subsection (1), the aim is—
(a) to intervene and provide services under this Part as early as is reasonably practicable after a worker suffers a work injury; and
(b) in connection with paragraph (a)—
(i) to return the worker to work in the worker's pre-injury duties; or
(ii) if it is not reasonably practicable to return the worker to work in the worker's pre-injury duties—to return the worker, either temporarily or permanently, to other suitable duties with the worker's pre-injury employer; or
(iii) if subparagraphs (i) and (ii) are not reasonably practicable—to return the worker, either temporarily or permanently, to work with another employer; or
(iv) if subparagraphs (i), (ii) and (iii) are not reasonably practicable—to maximise the worker's independent functioning as a member of the community; and
(c) to ensure that any employer, worker or other person involved in a recovery or return to work process cooperate to achieve the object referred to in subsection (1).
(3) This Part may apply to a worker even if it has not been finally established that the worker's injury is a work injury.
