The National Seas Act 1977 states that delimitation of boundaries in relation to neighboring states, the offshore seas of the State extend to a distance of 200 miles seaward from the baselines and, unless otherwise specified, shall be deemed to comprise all the waters outside the baselines and within a line proclaimed for the purposes of this section by the Head of State, acting on advice, in the National Gazette.

Work is still in progress with UN DOALOS to arrange for publication of Regulations made under the Maritime Zone Act 2015 which contains the coordinates and describes PNG's rights and jurisdiction over its EEZ.

Papua New Guinea PG: Land Area data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Papua New Guinea – Table PG.World Bank: Land Use, Protected Areas and National Wealth. Land area is a country's total area, excluding area under inland water bodies, national claims to continental shelf, and exclusive economic zones. In most cases the definition of inland water bodies includes major rivers and lakes.; ; Food and Agriculture Organization, electronic files and web site.; Sum;

The Government of Papua New Guinea has developed this National Marine Spill Contingency Plan (NATPLAN) as part of its commitment to protecting its and our valuable coastal and marine resources from the threat of marine pollution incidents. NATPLAN has been developed to reflect the essential steps necessary to initiate, conduct and terminate an emergency spill response on, or into the navigable waters of Papua New Guinea, on the adjoining shorelines, the waters of the contiguous zone or into waters of the exclusive economic zone.

This edition has been superseded by the Australia's Maritime Zones Edition 4 map published in October 2013. Geocat 69822. It no longer correctly reflects Australia's maritime zones and is kept for historical record only.

This map has been derived from Geoscience Australia's Australian Maritime Boundaries (AMB) version 2.0 data which is a digital representation of Australia's territorial sea baseline and the maritime limits and boundaries as established under the Sea and Submerged Lands Act 1973.

The map describes the different maritime zones, explains how Australia defines and updates its maritime boundaries, and lists the different maritime boundary arrangements with Indonesia, Papua New Guinea, Solomon Islands, France (New Calendonia and Kerguelen) and New Zealand.

The limits of the extended continental shelf beyond the exclusive economic zone, as shown on this map, are as submitted for consideration of the United Nations Commision on the Limits of the Continental Shelf (CLCS). In accordance with Australia's request the CLCS has indicated that it will not consider the extended continental shelf appurtenant to the Australian Antarctic Territory for the time being.

This map shows the extent of Australia's maritime boundaries, stretching from Heard and McDonald Islands in the west to Norfolk Island in the east, and from the Torres Strait and Arafura Sea in the north to the Australian Antarctic Territory in the south.

This map can be purchased in either flat or folded format. Also available as GIS data or PDF.

This dataset contains point data describing physical properties of marine sediments as held within the Geoscience Australia Marine Sediment database (MARS) for samples acquired by marine surveys that occurred between 1905 and 2017. Samples were collected from within the Australian Exclusive Economic Zone, plus waters within Australian Antarctic Territory, waters around Christmas Island (Indian Ocean) and outside the EEZ within the Timor Sea and waters around Papua New Guinea. Samples are sourced from a range of organisations, with sampling technique, spatial accuracy and sample preservation varying between surveys. Attributes include survey ID and name, sample ID, sampling method, water depth and location information. Sediment properties include %mud, %sand, %gravel, mean grain size and texture (classified using the Folk (1954) nomenclature for sediments). There is no consistent datum and projection due to the time span, differing collecting organisations and method of measurement across the dataset. All data is referenced to WGS 84 unless stated otherwise.

Abstract:This dataset depicts the limit of Australia’s territorial sea as proclaimed by the Seas and Submerged Lands Act 1973 – Proclamation under section 7 (9/11/1990). This Proclamation asserts a 12 nautical mile territorial sea measured seaward from the territorial sea baseline, with exception of certain islands in the Torres Strait where the territorial sea limit is fixed at 3 nautical miles in accordance with the Torres Strait Treaty between Australia and Papua New Guinea.

Swath-mapping of the seabed started soon after the Second World War, with small towed sidescan sonars providing images and built-in multi beam sonars providing bathymetry contour maps. Since then, variants of both systems have developed enormously to cover all water depths, and many of them can produce both acoustic imagery and contours. Today, swath widths of up to seven times the water depth allow rapid and accurate mapping. Swath-mapping has largely replaced the far less efficient single-beam profiling as a mapping tool. Several deepwater systems have been used on the Australian margin, and this paper concentrates on their use. At this stage, less than 5% of Australias offshore jurisdiction (larger than our onshore jurisdiction) has been mapped. HMAS Cook was brought into service in the 1960s with a very early SeaBeam multibeam system. Its most notable scientific successes were in 1989, when it was used in conjunction with the long-range towed GLORIA sidescan sonar system. Geologically important results were obtained off the Great Barrier Reef, south of Sydney, and west of Robe in South Australia. Since then, a number of transits through Australian waters, using modern SeaBeam systems, have been carried out by US institutions. In 1997, AGSO used R.V. Melville to map a large area off eastern Tasmania and in Bass Strait. Spectacular sidescan sonar images (with far higher resolution than those from GLORIA) and associated bathymetry have been obtained in the back-arc basins of Papua New Guinea by the SeaMarc II and HMR1 systems. The first major HMR1 survey in Australian waters was carried out in 1994 on the Macquarie Ridge with AGSO providing R.V. Rig Seismic as the platform. In 1994, AGSO used the French R.V. L Atalante with the Simrad EM12D multibeam system for mapping off Tasmania. The magnificent contour maps and images have revolutionised our geological understanding of an area three times that of Tasmania, and have enabled us to target seabed sampling programs for a greatly improved understanding of geological evolution and petroleum potential. These maps have been of substantial benefit to fishermen and biological and fisheries researchers, as have the Melville maps from eastern Tasmania. Several transit surveys using L Atalante have provided useful maps elsewhere off Australia. Government is considering how to develop our knowledge base to allow effective management of our vast offshore jurisdictional area: a 200 nautical mile Exclusive Economic Zone; and, beyond that, an extension of the legal Continental Shelf, which AGSO has been directed to map by 2004, to allow a maximum claim under the UN Law of the Sea provisions. A key element in management activities is adequate maps, which require methodical mapping of the seabed, using swath-mapping techniques. The RAN Hydrographic Service is acquiring vessels and systems capable of mapping the continental shelf. A national program, to map the entire Australian jurisdiction of 10 million km" beyond the continental shelf, but excluding the Australian Antarctic Territory, would take about 12 years and cost about $ 150 million, including all facets from acquisition to processing and storage, interpretation, and provision of digital data to the public. Such a program has strong multidisciplinary scientific, industrial and bureaucratic support, and would provide the information to properly manage our jurisdiction.

Papua New Guinea (PNG) has a total land area of 462,000 square kilometers (km2), making it the largest Pacific island country. Its exclusive economic zone at 3.12 million km2 is the world’s second largest. The country’s sparsely distributed population of only 7 million makes PNG’s population density of approximately 9 people per km2 the lowest in the South Pacific. PNG’s principal marine and coastal ecosystems include 13,840 km2 of coral reefs, 4,200 km2 of mangrove swamp forests, and extensive seagrass beds. The country is home to at least 500 species of stony coral, 1,635 reef-associated fish species, 43 mangrove species, and 7 seagrass species.
