WMS The Seas and Submerged Lands Act (SSLA) 1973 is the Australian legislation that provides the domestic legal framework for Australia to declare its international offshore maritime zones, as provided for by the United Nations Convention on the Law of the Sea (UNCLOS) to which Australia is a party. Proclamations under the SSLA establish the territorial sea baseline, the territorial sea, the contiguous zone, the exclusive economic zone and the continental shelf. This service depicts official spatial representation of these proclamations. The service includes feature layers: Normal and Straight baselines limits and locations; Contiguous Zone and limit; Territorial Sea Zone and limit; Exclusive Economic Zone (EEZ), limits and locations; Continental Shelf limit and locations. NOTE: There are two versions of the Exclusive Economic Zone (EEZ) provided. One depicts the EEZ as proclaimed in the Seas and Submerged Lands Act 1973 - Proclamation under section 10B (26/07/1994). The second version includes amendments reflecting the provisions of the signed but not yet ratified Treaty between the Government of Australia and the Government of the Republic of Indonesia, establishing an Exclusive Economic Zone Boundary and Certain Seabed Boundaries (Perth, 14 march 1997). The version reflecting the Perth Treaty EEZ limits and area should be the standard depiction.

These limits include the breadth of the territorial sea, the seaward limit of the contiguous zone, exclusive economic zone and, in some cases, the continental shelf. The territorial sea baseline also constitutes the inner limit of the territorial sea of Australia, waters on the landward side of the baseline are internal waters of Australia for the purposes of international law. The territorial sea baseline does not represent the constitutional limits of Australia’s States or Territories.The territorial sea baseline is composed of both normal and straight baselines. This dataset depicts the Straight Territorial Sea Baselines of Australia as proclaimed in the Seas and Submerged Lands (Territorial Sea Baseline) Proclamation 2016. This proclamation declares defined geographic coordinates for Australia’s straight baselines where, according to the principles set out in articles 7, 9 and 10 of UNCLOS, straight baselines have been drawn across the mouths of certain bays and rivers, and between the mainland and adjacent islands in some circumstances.

This dataset depicts the Normal Territorial Sea Baselines of Australia as proclaimed in the Seas and Submerged Lands (Territorial Sea Baseline) Proclamation 2016. This proclamation declares that the normal baseline is the low water line along the coast, including the coasts of islands. For the purposes of the proclamation the low water line is defined as the lowest astronomical tide (LAT). Normal baselines are also drawn around low tide elevations, which are defined as naturally formed areas of land surrounded by and above water at low tide but submerged at high tide, where they are wholly or partly within 12 nautical miles of the coast.
