The object of this Part is to provide for agreements between the Commonwealth and a State or self - governing Territory that:
(a) protect the environment; and
(b) promote the conservation and ecologically sustainable use of natural resources; and
(c) ensure an efficient, timely and effective process for environmental assessment and approval of actions; and
(d) minimise duplication in the environmental assessment and approval process through Commonwealth accreditation of the processes of the State or Territory (and vice versa).
