The Marine Park and Management Plan
4 The EPBC Act regulates (amongst other things) commercial fishing in Commonwealth waters through the use of designated Commonwealth Reserves. Rules, including those contained in management plans in operation for a Commonwealth Reserve, manage activities within that reserve. Management plans are prepared and approved in accordance with Subdiv E of Div 4 of Pt 15 of the EPBC Act. Sections 354 and 354A of the EPBC Act, subject to certain specified exceptions, provide for the imposition of civil penalties and criminal sanctions in respect of certain activities carried out within a Commonwealth Reserve otherwise than in accordance with a management plan in operation for the reserve.
5 The Marine Park is a Commonwealth Reserve declared under the EPBC Act. The Marine Park is located west of the Tiwi Islands, approximately 155 km north-west of Darwin, Northern Territory, and 305 km north of Wyndham, Western Australia. It extends to the limit of Australia's exclusive economic zone and covers an area of 71,743 km².
6 The Marine Park contains the following seafloor and ecological features: the carbonate terrace and bank system of the Van Diemen Rise, carbonate bank and terrace systems of the Sahul Shelf, pinnacles of the Bonaparte Basin, and shelf break and slope at the Arafura Shelf.
7 The Marine Park is home to a high diversity and density of fish species (including both non-endangered fish species, and those listed as threatened, migratory, marine or cetacean under the EPBC Act). Biologically important areas, which reflect habitat critical to the survival of a species or ecological community, within the Marine Park include foraging and inter-nesting habitat for marine turtles, including endangered Olive Ridley, and vulnerable Hawksbill, Green and Flatback turtles.
8 The Management Plan is in operation for the Marine Park, with effect from 1 July 2018. The Management Plan divided the Marine Park into four designated zones: "Special Purpose Zone", "Multiple Use Zone", "Habitat Protection Zone" and "National Park Zone".
9 Of relevance to this application is the Habitat Protection Zone. The objective of the Habitat Protection Zone is to provide for the conservation of ecosystems, habitats and native species in as natural a state as possible while allowing activities that do not harm or cause destruction to seafloor habitats.
10 The carbonate bank and terrace systems of the Van Diemen Rise extend into the Habitat Protection Zone. These ecological features are characterised by diverse benthic habitats supporting sponges, soft corals, polychaetes, ascidians, turtles, sea snakes, sharks and marine mammals. Flatback turtles nest only in Australia and the Arafura Sea population use the Habitat Protection Zone as an inter-nesting habitat. The north-western section of the Habitat Protection Zone overlays part of the Timor Reef Fishery.
11 Under the Management Plan, trap fishing for commercial purposes is prohibited in the Habitat Protection Zone. Trap fishing involves the laying of fish traps. A fish trap is a cage or a box, which sometimes contains bait, that is used to collect fish and crustaceans. The cage typically consists of a metal frame and wire or string mesh cover with an entrance that allows species to enter but not leave the trap. Fish traps have escape gaps of a minimum size to ensure juvenile and some non-target fish are able to escape. The bottom of the trap is weighted to ensure it sinks to the seafloor and lands upright. The cage is attached to a length of rope that attaches to a surface float and marker buoy to aid location and retrieval. Retrieval typically occurs by grappling the main line between the marker buoy and the float and pulling it back onboard.
