Polygons representing a qualitative estimate of the potential for hydraulic interconnection between the base of the Great Artesian Basin and top of underlying basement units. This dataset is derived from the 'Hydrogeological basement units in contact with the base of the Great Artesian Basin' dataset (Geoscience Australia, catalogue #75910, 2013) and 'Base Great Artesian Basin hydrogeological units in contact with basement' dataset (Geoscience Australia, catalogue #75911, 2013). It is used to identify potential hydraulic interconnection between the Great Artesian Basin and basement units. Data is available as polygons in Shapefile format This GIS data set was produced for the Great Artesian Basin Water Resource Assessment and used in Figure 3.6 of Smerdon BD, Ransley TR, Radke BM and Kellett JR (2012) Water resource assessment for the Great Artesian Basin. A report to the Australian Government from the CSIRO Great Artesian Basin Water Resource Assessment. CSIRO Water for a Healthy Country Flagship, Australia. This dataset and associated metadata can be obtained from www.ga.gov.au, using catalogue number 75839.

Contains a medium scale vector representation of the topography of Australia. The data include the following themes: Hydrography - drainage networks including watercourses, lakes, wetlands, bores and offshore features; Infrastructure - constructed features to support road, rail and air transportation as well as built-up areas, localities and homesteads. Utilities, pipelines, fences and powerlines are also included; Relief - features depicting the terrain of the earth including 50 metre contours, spot heights, sand dunes, craters and cliffs; Vegetation - depicting forested areas, orchards, mangroves, pine plantations and rainforests; and Reserved Areas - areas reserved for special purposes including nature conservation reserves, aboriginal reserves, prohibited areas and water supply reserves.

The approximate location of the Helidon Ridge (proposed name) - a basement ridge likely to define the hydrogeological boundary between the Surat and Clarence-Moreton basins in the GAB. To be used in conjunction with dataset 'Groundwater divide in the Hutton Sandstone boundary' (Geoscience Australia, Catalogue #77024, 2013) to define the easternmost boundary of the GAB. The approximate location of the Helidon ridge was interpreted from a GOCAD model layer of Base of Hutton Sandstone surface (Geoscience Australia dataset, Catalogue #76025, 2013). This data set provides an approximate location of Helidon ridge as a polygon in Shapefile format. The polygon represents the area in which the boundary is likely to be located, as the exact location is open to interpretation. Data is available in Shapefile format This data set was used in: Figure 5.3 in Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin.

This map shows public and private land tenure, including Aboriginal and Torres Strait Islander land for the whole of Australia at a scale of 1:4.7 million. The land tenure boundaries depicted on this map generally define broadly classified areas greater than 50 square kilometres. Aboriginal land areas between 0.1 and 100 square kilometres are shown more comprehensively by symbols. The information on this map is complemented by statistical tables giving the total area of the land tenure categories for each state and territory. Also available as GIS data.

AMB is a dataset depicting the limits of Australia's maritime jurisdiction as set out under UNCLOS and relevant domestic legislation. To this extent, AMB provides a digital representation of the outer limit of the 12 nautical mile territorial sea, the 24 nautical mile contiguous zone, the 200 nautical mile Exclusive Economic Zone and Australia's Continental Shelf, as well as, the 3 nautical mile coastal waters. Where Australia has agreements with neighbouring countries these treaty lines are also included in the data. The dataset has been compiled by Geoscience Australia in consultation with other relevant Commonwealth Government agencies including the Attorney-General's Department, the Department of Foreign Affairs and Trade, as well as the Australian Hydrographic Office.

A revolution is underway in the regulatory intensity of the marine jurisdiction and the technologies by which the jurisdiction is defined, navigated on and policed. This revolution if not properly managed has the capacity to undermine the technical and legal compact by which the most fundamental aspects of UNCLOS are managed - the maritime zones. The ready availability of high resolution coastal imagery and data, collected at high repeat cycles breaks the nexus between cartographic products and the baseline determination where its legal definition is the physical coastline. It is impractical to monitor, compute, distribute and archive the baseline of a highly dynamic coastline. In addition, the increasing establishment of spatially complex marine regulations creates an insatiable demand for more certainty in the determination of maritime zones. For instance, Australia administers over eighty separate regulatory zones through a dozen different agencies. States require a new method of characterising their baselines that is defensible in a precise digital world, and does not impose the costly and burdensome process of mapping a coastline in constant flux. The practical resolution is to adopt a fixed baseline compiled from the best available digital data at an epoch, then periodically updated it when considered appropriate. A fixed baseline is the answer to this problem which will bring with it certainty and repeatability via a method that recognises the costly and complex overhead of coastline characterisation. In this paper I will present a case for the adoption of a fixed baseline; illustrate the expensive impracticality of attempting to represent a fluid coastline to a world demanding certainty; how fixed baselines could form the basis of maritime zones; and finally demonstrate that adopting a fixed baseline is consistent with and desirable to International convention.

This dataset attempts to reflect the boundaries of claimant applications for Native Title as per the Register of Native Title Claims (s185, Native Title Act; Commonwealth). This is a national dataset but data is stored by jurisdiction (State), for ease of use. Applications stored for each jurisdiction dataset include applications which overlap into adjoining jurisdictions as well as applications which overlap with these. This dataset depicts the spatial record of registered claimant applications. Aspatial attribution includes National Native Title Tribunal number, Federal Court number, application status and the names of both the NNTT Case Manager and Lead Member assigned to the application. Applicants of registered applications have the Right To Negotiate (RTN) with respect to certain types of Future Acts over the area being claimed. Whilst applications that are determined are recorded on a separate register, all registered applications remain on the Register of Native Title Claims until otherwise finalised.

This two-sided map shows the nation`s official Australia Post postcode and sorting division boundaries. Printed in four colours, the map shows state boundaries, city and town names and other important topographic features. Major urban areas are clearly shown in a series of individual enlargements. The map is available folded and flat as a handy wall chart.

The Cadastral dataset is the spatial representation of property boundaries and descriptions in the Barcaldine, Charters Towers, Flinders, Longreach and Winton local government areas. It is a fundamental reference layer for spatial information systems in Queensland. This is a complete extract from the Digital Cadastral Database (DCDB). Updates to this cadastre in 2012 will be released on the following dates: January 15 and 29 - February 12 and 26 - March 11 and 25 - April 8 and 22 - May 6 and 20 - June 3 and 17 - July 1, 15 and 29 August 12 and 26 - September 9 and 23 - October 7 and 21 - November 4 and 18 - December 2, 16 and 30. In 2013 the 1st release date will be January 13.

This abstract is to be submitted for the Great Artesian Basin Coordinating Committee Researcher's Forum on 27th-28th of March, as part of the Great Artesian Basin Water Resource Assessment launch at the event.
