Abstract: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.© Commonwealth of Australia (Geoscience Australia) 2021.Downloads and Links:Web ServicesSeas and Submerged Lands Act 1973 MapServer Seas and Submerged Lands Act 1973 WMTSSeas and Submerged Lands Act 1973 WMSSeas and Submerged Lands Act 1973 WFSDownloads available from the expanded catalogue link, belowMetadata URL:https://pid.geoscience.gov.au/dataset/ga/144571
