The dataset was created by Geoscience Australia using the framework described in Section 33 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act) and previous Acts. The international, scheduled areas and coastal waters used in this dataset are those found in the current Australian Maritime Boundary Dataset 2020 (AMB2020). The 2020 release has been updated to reflect the 2018 Timor Sea Treaty. Available for download in GDA94 or GDA2020. The dataset is comprised of both polygons and points created to very high precision, accurate to within millimetres. The blocks have been cut by Australia's international boundaries, the scheduled areas and the coastal waters. Each block is assigned a polygon, including partial blocks. All blocks are titled with their block ID, and a list of vertices that make up the blocks. Each vertex of the dataset is also replicated as a discrete point in the points dataset. The design of the dataset allows for the exact location of every vertex to be known to millimetre precision. The corner coordinates of blocks are now defined to a high precision, and can be found by querying the appropriate point. The blocks are attributed with fields containing information on: - Block ID - Parent 1 Million Mapsheet - Offshore Area - Epoch of the boundaries used to cut the data AMB2014 - Datum - Origin of the mapsheet in AGD66 - The position of all vertices in the block - The number of vertices in the block - The area of the block in acres - The area of the block in hectares The calculation used to find the area of the blocks is estimated to be precise to better than 1%. This is considered to be sufficient as under the permit and licensing arrangements in the OPGGS Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference.

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 Australian Maritime Boundaries 2014 (AMB2014), providing access to the data for Australia's maritime zones. AMB is a digital representation of Australia's limits and boundaries as established under the Seas and Submerged Lands Act 1973 and associated proclamations. The data also include a representation of the limits by which the scheduled and offshore areas of each of the States and of the Northern Territory are determined under the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA). In the event of an inconsistency between AMB data and the limits under any 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. 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 AMB data comprise the territorial straight baselines and the outer limits of each zone, together with maritime boundaries determined by treaties between Australia and neighbouring countries. All data coordinates are supplied in the GDA94 datum. The data reflects the location of the coastline within the constraints of available source material at the time of production. AMB Data 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 AMB data 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 7 S to 70 S and the longitude limits 40 E to 175 E. This dataset includes the following disclaimer: AMB data is a digital representation of the territorial sea baseline and of the outer limits of Australia's maritime zones. The baseline and zones are established under the Seas and Submerged Lands Act 1973. The data also includes a representation of the limits by which the waters adjacent to each of the Australian States and of the Northern Territory are determined under the Coastal Waters (State Powers) Act 1980, Coastal Waters (Northern Territory Powers) Act 1980 and the Offshore Petroleum and Greenhouse Gas Storage Act 2006. In the event of an inconsistency between AMB data and the baselines and limits under the legislation, the latter prevails.

The revised Great Artesian Basin Jurassic-Cretaceous boundary was produced by the Great Artesian Basin Water Resource Assessment (GABWRA) . This boundary is modified from that of Habermehl and Lau 1997 and incorporates the revised boundary from the South Australia Great Artesian Basin (Eromanga Basin) Hydrogeological map 2012. Modifications made to sections of this boundary as part of the GABWRA include major revisions to the Surat and Clarence-Moreton Basins boundary; southern part of the Coonamble Embayment; NW Queensland boundary within the Lawn Hill and Westmoreland 1:250K map sheet areas. The dataset includes boundaries of basement inliers within the GAB Note: Habermehl and Lau 1997 boundary included Triassic GAB formations in Queensland which were not considered by the GABWRA. Data is available in polygon format. REFERENCE: Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin.
