  • Geoscience Australia has the primary role in the delineation of Australia's domestic and international maritime limits and boundaries. An output of this activity is the development of the Australian Maritime Boundaries (AMB) data. AMB is a GIS data product, replacing AMBIS 2006, providing access to the data for Australia's maritime zones. Treaties - Australian Maritime Boundaries Dataset 2014 is a digital representation of Australia's international treaty boundaries. In the event of an inconsistency between AMB data and the limits under any treaty, the latter prevails. The data have been published by Geoscience Australia in consultation with other relevant Commonwealth Government agencies including the Attorney-General's Department, the Department of Foreign Affairs and Trade and the Australian Hydrographic Office. This version contains a number of technical amendments made on the basis of user feedback. These include: - Harmonisation of maritime boundaries, scheduled area and graticular block datasets in block SC51 The Treaties - Australian Maritime Boundaries Dataset 2014a comprises the maritime boundaries determined by treaties between Australia and neighbouring countries. All data coordinates are supplied in the GDA94 datum. Treaties - Australian Maritime Boundaries Dataset 2014a can also be viewed on-line via AMSIS (http://www.ga.gov.au/marine/jurisdiction/amsis.html). Product Specifications Coverage: Australia including all external territories Currency: May 2014. Coordinates: Geographical Datum: GDA94 (functionally equivalent to WGS84). Format: ESRI Geodatabase and REST web service - free online. The area of coverage of the Treaties - Australian Maritime Boundaries Dataset 2014 is for the whole of the Australian marine jurisdiction which includes waters adjacent to the mainland, offshore islands and External Territories. The geographical extent is approximately between the latitude limits of 8 S to 70 S and the longitude limits 39 E to 174 E. This dataset includes the following disclaimers: AMB data is a digital representation of the international maritime boundary treaties of Australia. In the event of an inconsistency between AMB data and the limits under the various treaties, the latter prevails.

  • Geoscience Australia is responsible for the definition of Australia's maritime boundaries. To assist in this task National Mapping has developed the Australian Maritime Boundaries Information System (AMBIS). AMBIS 2001 is a data product, derived from AMBIS, providing access to the data for Australia's Territorial Sea Baseline (TSB) and maritime zones. AMBIS 2001 data comprises the TSB and the outer limits of each zone, together with quality attributes. Base points that generate the zone boundaries are supplied in separate files and an extensive user guide provides useful background information. All data coordinates are supplied in the Geocentric Datum of Australia (GDA 94) which is effectively identical to the WGS84 datum. National Mapping is committed to the maintenance of the AMBIS data to ensure it reflects the changing nature of Australia's coastline and hence the various maritime zone limits. To this effect, a newly revised AMBIS 2001 product (version 1.1) has been released in October 2001. This new version incorporates additional treaty information, additional data in the vicinity of Swains Reef in Queensland, an improved representation of the TSB, several other minor corrections, a wider range of formats and simplified attribute tables.

  • The service contains all maritime boundaries treaties signed by Australia (NOT ALL ARE IN FORCE). Where the original datum of the treaty is not specified as GDA94, all defined points have been transformed by Geoscience Australia's National Geospatial Reference Systems Section to GDA94.

  • Geoscience Australia has the primary role in the delineation of Australia's domestic and international maritime limits and boundaries. An output of this activity is the development of the Australian Maritime Boundaries (AMB) database. The current epoch of this database is 2019. It differs from previous epochs by including the Treaty information relevant to the maritime boundary treaty ratified with Timor-Leste on 30 August 2019. This data product contains the digital representation of the treaty between Australia and Timor-Leste. AMB data is published by Geoscience Australia in consultation with other relevant Commonwealth Government agencies including the Attorney-General's Department, the Department of Foreign Affairs and Trade and the Australian Hydrographic Office.. Data coordinates are supplied in the GDA94 datum. Treaties with Timor-Leste - Australian Maritime Boundaries Dataset 2019 will be accessible via the Australian Maritime Spatial Information System (AMSIS) (http://www.ga.gov.au/scientific-topics/marine/jurisdiction/amsis). Product Specifications Coverage: Australia and Territories, current September 2019. Coordinates: Geographical Datum: GDA94 (operationally equivalent to WGS84). Format: ESRI Geodatabase and Shapefile. The geographical extent is approximately between the latitude limits of 9.5 S to 11.5 S and the longitude limits 126 E to 128.5 E. This dataset includes the following disclaimers: AMB data is a digital representation of the international maritime boundary treaties of Australia. In the event of an inconsistency between AMB data and the limits under the various treaties, the latter prevails.

  • PLEASE NOTE: These data have been updated. See Related Links for new data. Geoscience Australia has the primary role in the delineation of Australia's maritime boundaries. An output of this activity is the development of the Australian Maritime Boundaries (AMB) data. AMB is a GIS data product, replacing AMBIS 2001 Version 1.1, providing access to the data for Australia's Territorial Sea Baseline (TSB) and maritime zones. AMB is a digital representation of Australia's territorial sea baseline and boundaries as established under the Seas and Submerged Lands Act 1973. The data also include a representation of the limits by which the adjacent areas of each of the States and of the Northern Territory are determined under the Petroleum (Submerged Lands) Act 1967. In the event of an inconsistency between AMB data and the baseline and limits under the legislation, the latter prevails. The data have been published by Geoscience Australia in consultation with other relevant Commonwealth Government agencies including the Attorney-General's Department, the Department of Foreign Affairs and Trade and the Australian Hydrographic Office. AMB data comprise the TSB and the outer limits of each zone, together with maritime boundaries determined by treaties between Australia and neighbouring countries. Base points that generate the zone boundaries are supplied in separate files and an extensive user guide provides useful background information. All data coordinates are supplied in the World Geodetic System (WGS 84) (ITRF 2000 @ 2000.0) which is effectively identical to the GDA94 datum. Geoscience Australia is committed to the maintenance of the maritime boundaries data to ensure it reflects the changing nature of Australia's coastline and hence the various maritime zone limits. The data reflects the location of the coastline within the constraints of available source material at the time of production. Where major differences have since been discovered, these are listed in a table of notes and cautions. AMB Data can now also be viewed on-line via AMSIS.
