The Offshore Constitutional Settlement (OCS) is an agreement between the Commonwealth of Australia and the States which provides the basis for an agreed division of powers between the Commonwealth and the States in relation to coastal waters and in relation to certain other matters including the regulation of shipping and navigation, offshore petroleum exploration, crimes at sea, and fisheries. [1]
The United Nations treaty, the Convention on the Territorial Sea and the Contiguous Zone defines "the contiguous zone" as not extending beyond "twelve miles from which the baseline from which the breadth of the territorial sea is measured." [2]
The Seas and Submerged Lands Act 1973 incorporates the Convention on Territorial Sea and Contiguous Zone 1958 in domestic law. [3]
The six states took the federal Government to court over the Seas and Submerged Lands Act 1973. [4] [5] [6] The High Court of Australia upheld the act and asserted that control over the coastal waters was in the hands of the Commonwealth. [7]
On 29 June 1979, the Commonwealth and the states completed an agreement called the "Offshore constitutional settlement". [8]
The agreement outlines several different points of the agreement:
The Coastal Waters (State Powers) Act 1980 vests the states the power to legislate within 3 nautical miles. [9]
The Coastal Waters (State Title) Act 1980 vests the states the right and title to the property within 3 nautical miles. [10]
The Coastal Waters (Northern Territory Powers) Act 1980 vests the Northern Territory the title of within 3 nautical miles. [11]
The Coastal Waters (Northern Territory Title) Act 1980 vests the Northern Territory the right and title to the property within 3 nautical miles. [12]
Under the Crimes at Sea Act 2000 (Cth), the criminal law of each state applies to all 12 miles of the territorial sea. [13] [14]
Until the settlement there had never been any national oceans policy. [15] The OCS has been described as reflecting Australia's "inherently federal public policy-making". [16]
The settlement has drawn comparisons to the United States' and Canada's federalist arrangements. [17] Unlike Australia, the Canadian federal government has attempted to assert a 12-mile territorial sea, and only Newfoundland and Labrador has been able to assert a 3-mile sea. [17] The equivalent arrangements for the United States are governed by the Submerged Lands Act. [18]
The settlement has been described as an "intergovernmental arrangement to sidestep an unpopular High Court decision" rather than a constitutional settlement. [19]
The situation created by the settlement has been criticised as a "muddle" of state and Northern Territory laws. [20]
The United Nations Convention on the Law of the Sea (UNCLOS), also called the Law of the Sea Convention or the Law of the Sea Treaty, is an international treaty that establishes a legal framework for all marine and maritime activities. As of October 2024, 169 sovereign states and the European Union are parties.
The Jervis Bay Territory is an internal federal territory of Australia. It was established in 1915 from land ceded by the state of New South Wales, in order to give the federal government access to the sea in the vicinity of the landlocked Australian Capital Territory (ACT).
In the United States, a territory is any extent of region under the sovereign jurisdiction of the federal government of the United States, including all waters. The United States asserts sovereign rights for exploring, exploiting, conserving, and managing its territory. This extent of territory is all the area belonging to, and under the dominion of, the United States federal government for administrative and other purposes. The United States total territory includes a subset of political divisions.
Territorial waters are informally an area of water where a sovereign state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone, and potentially the extended continental shelf. In a narrower sense, the term is often used as a synonym for the territorial sea.
Law of the sea is a body of international law governing the rights and duties of states in maritime environments. It concerns matters such as navigational rights, sea mineral claims, and coastal waters jurisdiction. The connotation of ocean law is somewhat broader, but the law of the sea is so comprehensive that it covers all areas of ocean law as well.
An exclusive economic zone (EEZ), as prescribed by the 1982 United Nations Convention on the Law of the Sea, is an area of the sea in which a sovereign state has exclusive rights regarding the exploration and use of marine resources, including energy production from water and wind.
Native title is the set of rights, recognised by Australian law, held by Aboriginal and Torres Strait Islander groups or individuals to land that derive from their maintenance of their traditional laws and customs. These Aboriginal title rights were first recognised as a part of Australian common law with the decision of Mabo v Queensland in 1992. The doctrine was subsequently implemented and modified via statute with the Native Title Act 1993.
The legal system of Australia has multiple forms. It includes a written constitution, unwritten constitutional conventions, statutes, regulations, and the judicially determined common law system. Its legal institutions and traditions are substantially derived from that of the English legal system, which superseded Indigenous Australian customary law during colonisation. Australia is a common-law jurisdiction, its court system having originated in the common law system of English law. The country's common law is the same across the states and territories.
Ruddock v Vadarlis was an Australian court case decided in the Federal Court of Australia on 18 September 2001. It concerned the actions of the Government of Australia in preventing asylum seekers aboard the Norwegian cargo vessel MV Tampa from entering Australia in late August 2001. The Victorian Council for Civil Liberties, and solicitor Eric Vadarlis, were seeking a writ of habeas corpus. The case is significant because it is one of the few cases to consider the nature and scope of the prerogative power of the executive branch of Government in Australia.
The states and territories are the second level of government of Australia. The states are partially sovereign, administrative divisions that are self-governing polities, having ceded some sovereign rights to the federal government. They have their own constitutions, legislatures, executive governments, judiciaries and law enforcement agencies that administer and deliver public policies and programs. Territories can be autonomous and administer local policies and programs much like the states in practice, but are still legally subordinate to the federal government.
Yarmirr v Northern Territory was an Australian court case, decided in 2001. It was an application for the determination of native title to seas, sea-bed and sub-soil, over an area in the Northern Territory, ultimately determined on appeal to the High Court of Australia.
The Outer Continental Shelf (OCS) is a legally defined geographic feature of the United States. The OCS is the part of the internationally recognized continental shelf of the United States which does not fall under the jurisdictions of the individual U.S. states.
Tidelands are the territory between the tide line of sea coasts, and lands lying under the sea beyond the low-water limit of the tide, considered within the territorial waters of a nation. The United States Constitution does not specify whether ownership of these lands rests with the federal government or with individual states. Originally little commercial value was attached to tidelands, so ownership was never firmly established, but the coastal states generally proceeded as if they were the owners. Some states, such as Mississippi, directly administer these lands under the public trust doctrine.
Australian mining law governs the exploration and extraction of minerals and petroleum in Australia. It differs substantially from the mining laws of other common law countries, the most important differences arising from the policy decision that the Crown should own all minerals.
The Australian Fisheries Management Authority (AFMA) is the Australian Government agency responsible for the management and sustainable use of fisheries resources including combating illegal fishing activities in the Australian Fishing Zone that covers 8,148,250 square kilometres, the third largest in the world, and in most of Australia's Exclusive Economic Zone, which extends to 200 nautical miles (370 km) from the coastline of Australia and its external territories, except where a maritime delimitation agreement exists with a state. AFMA is an agency of the Australian Department of Agriculture, Fisheries and Forestry. The Authority does not have a legal identity separate from the Commonwealth.
The Submerged Lands Act of 1953 is a U.S. federal law that recognized the title of the states to submerged navigable lands within their boundaries at the time they entered the Union. They include navigable waterways, such as rivers, as well as marine waters within the state's boundaries, generally three geographical miles from the coastline.
Rivoli Bay is a bay located on the south-east coast of the Australian state of South Australia, about 311 kilometres south-southeast of the state capital of Adelaide and about 65 kilometres northwest by west of the regional centre of Mount Gambier. It was named in 1802 by the Baudin expedition of 1800–03 after André Masséna, the Duke of Rivoli and Marshal of France. It is one of four 'historic bays' located on the South Australian coast.
Lacepede Bay is a bay in the Australian state of South Australia located on the state's south-east coast about 140 kilometres northwest of Mount Gambier and about 240 kilometres southeast of Adelaide. It was named in 1802 by the Baudin expedition of 1800-03 after Bernard Germain de Lacépède, the French naturalist. It is one of four ‘historic bays’ located on the South Australian coast.
Anxious Bay is a bay in the Australian state of South Australia located on the west coast of Eyre Peninsula about 275 kilometres west north-west of Adelaide. It was named by Matthew Flinders on 21 February 1802. It is one of four ‘historic bays’ located on the South Australian coast.
SS Kalibia v Wilson, was the first decision of the High Court of Australia on the extent of the power of the Australian Parliament to make laws about shipping and navigation, including the Admiralty jurisdiction of the High Court. The High Court held that the power was limited to overseas and interstate trade and commerce. There was no separate power about navigation and shipping.
