5Overall purpose

5 Overall purpose (1) The overall purpose of this Act is to protect the Territory's marine and coastal environment by minimising intentional and negligent discharges of ship-sourced pollutants into coastal waters. (2) This purpose is to be achieved primarily by giving effect to relevant provisions of the following annexes of MARPOL: (a) Annex I (which deals with pollution by oil); (b) Annex II (which deals with pollution by noxious liquid substances in bulk); (c) Annex III (which deals with pollution by harmful substances in packaged form); (d) Annex V (which deals with pollution by garbage). (3) The purpose is also to be achieved by: (a) providing an approach to protecting the Territory's marine and coastal environment from ship-sourced pollutants complementary to the approach of the Commonwealth and the States of the Commonwealth; (b) making provision about the discharge of sewage from ships; (c) enabling shipping casualties that are polluting, or threatening to pollute, coastal waters, to be dealt with; and (d) imposing severe penalties on persons who pollute the Territory's marine and coastal environment in contravention of this Act.
