This service has been created specifically for display in the National Map and the chosen symbology may not suit other mapping applications. The Australian Topographic web map service is seamless national dataset coverage for the whole of Australia. These data are best suited to graphical applications. These data may vary greatly in quality depending on the method of capture and digitising specifications in place at the time of capture. The web map service portrays detailed graphic representation of features that appear on the Earth's surface. These features include the administration boundaries from the Geoscience Australia 250K Topographic Data, including state forest and reserves.

Offshore Minerals Act (OMA 1994) - Mineral Blocks. This service displays the most recent realisation of the Mineral Blocks as defined under the Offshore Minerals Act 1994 (OMA 1994) as realised in GDA94. Block data extends beyond the area of operation of the OMA and includes areas of coastal waters and land within the constitutional limits of the States and Territories.

The dataset was created by Geoscience Australia using the framework described in Section 33 of the Offshore Minerals Act 1994. The international, scheduled areas and coastal waters used in this dataset are those found in the historical Australian Maritime Boundary Dataset 2006 (AMB2006). 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 AMB2006 -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 Offshore Minerals Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference. This dataset is published with the permission of the CEO, Geoscience Australia

Australian Mineral Blocks (2014) - Aligned with the current Australian Maritime Boundary Dataset (AMB2014). ESRI Geodatabase. The dataset was created by Geoscience Australia using the framework described in Section 17 of the Offshore Minerals Act 1994. The international, scheduled areas and coastal waters used in this dataset are those found in the current Australian Maritime Boundary Dataset 2014 (AMB2014). The dataset is comprised of both polygons and points created to very high precision, accurate to within millimetres.

Map showing Australia's Maritime Jurisdiction off the Northwest Shelf. Updated in June 2014 from "Australia's Maritime Jurisdiction off the Northwest Shelf" (GeoCat 69341) to conform with "Australian Maritime Boundaries 2014" data by Geoscience Australia. One of the 27 constituent maps of the "Australia's Maritime Jurisdiction Map Series" (GeoCat 71789). Depicting Australia's continental shelf as proclaimed in the "Seas and Submerged Lands (Limits of Continental Shelf) Proclamation 2012" established under the "Seas and Submerged Lands Act 1973". Background bathymetric image is derived from a combination of the 2009 9 arc second bathymetric and topographic grid by GA and a grid by Smith and Sandwell, 1997. Background land imagery derived from Blue Marble, NASA's Earth Observatory. A0 sized .pdf downloadable from the web.

Northern Australia Infrastructure Facility (NAIF) is a development financier to infrastructure projects in the Northern Territory, Queensland, Western Australia and the Australian Indian Ocean Territories. NAIF’s mission is to be an innovative financing partner in the growth of northern Australia. A key focus of any financing is to drive public benefit, economic, population growth, and Indigenous involvement in northern Australia. This NAIF dataset contains the limit and extent of Northern Australia as defined in the Northern Australia Infrastructure Facility Act 2016 including the Northern Australia Infrastructure Facility Amendment (Extension and Other Measures) Bill 2021 and the Northern Australia Infrastructure Facility Amendment (Miscellaneous Measures) Bill 2023. This is a maintained dataset and is kept updated to reflect any amendments to the legislation. The definition in the Northern Australia Infrastructure Facility Act 2016 states that Northern Australia means the area that includes the following: </div><div>&nbsp; (a)&nbsp;&nbsp;&nbsp;the Northern Territory; </div><div>&nbsp; (b)&nbsp;&nbsp;&nbsp;the areas of Queensland and Western Australia that are North of the Tropic of Capricorn </div><div>&nbsp; &nbsp;&nbsp;&nbsp;other than the Meekatharra Statistical Area level 2; </div><div>&nbsp; (c)&nbsp;&nbsp;&nbsp;the areas South of the Tropic of Capricorn of each Statistical Area level 2 that has an area </div><div>&nbsp; &nbsp; &nbsp;&nbsp;&nbsp;covered by paragraph&nbsp;(b); </div><div>&nbsp; (d)&nbsp;&nbsp;&nbsp;the following Statistical Areas level 2:&nbsp; </div><div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;Gladstone; </div><div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii)&nbsp;Gladstone Hinterland; </div><div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;Carnarvon;</div><div>(da)&nbsp;&nbsp;&nbsp;the Territory of Christmas Island; </div><div>(db)&nbsp;&nbsp;&nbsp;the Territory of Cocos (Keeling) Islands; </div><div>&nbsp; (e)&nbsp;&nbsp;&nbsp;&nbsp;the Local Government Areas of Meekatharra and Wiluna (despite paragraph&nbsp;(b)); </div><div>(ea)&nbsp;&nbsp;&nbsp;&nbsp;the Local Government Area of Ngaanyatjarraku; </div><div>&nbsp; (f)&nbsp;&nbsp;&nbsp;&nbsp;the territorial sea adjacent to areas covered by paragraphs&nbsp;(a) to (db).</div><div><br></div><div><br></div><div><br></div>
