Contains boundary and attribute information for parcels of public, private and Aboriginal lands in Australia. Data are sourced primarly from government gazette notices, cadastral maps and plans. A nominal scale of around 1:5 million and a minimum 50 square kilometre threshold limit for land parcels was used in the generalisation of this product from the National Public and Aboriginal Lands data. Data is suitable for GIS applications. This map shows public and private land tenure, including Indigenous 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. Indigenous 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. This map is also available as free vector GIS data, ArcInfo Export, ArcView Shapefile and MapInfo mid/mif. Please direct any corrections or feedback on this map to mapfeedback@ga.gov.au.

This dataset reflects the external boundaries of all native title determination and compensation applications that are currently recognized and active within the Federal Court process. Applications that are non-active (i.e. withdrawn, dismissed, finalised, rejected or combined) are only included as aspatial records for completeness. This is a national dataset with data partitioned 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 for completeness. This dataset depicts the spatial definition of active Claimant and Non-claimant native title determination applications and compensation applications. Where possible these may include internal boundaries or areas excluded. 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 where assigned to the application. Applications included on the Schedule of Native Title (Federal Court) include all registered and unregistered applications as well as determined applications that are yet to be finalized. Geospatial data portraying native title information produced by the National Native Title Tribunal may not be on-sold. Value added products using this data must acknowledge the National Native Title Tribunal as the data source and include the NNTT disclaimer.

This dataset reflects the boundaries of claimant and nonclaimant native title applications that have been determined in part or in full, together with attribution about that determination. This dataset is stored nationally. The National Native Title Register (s192, Native Title Act, Commonwealth), is a register containing information about each determination of native title by the Federal or High Court or by a recognized State or Territory body. Determinations are categorized by both process and outcome. Process will be by consent, litigation or unopposed. Outcome will be that native title will have been found to exist in full or part, or been extinguished. Those determinations subject to appeal are also noted. Geospatial data portraying native title information produced by the National Native Title Tribunal may not be on-sold. Value added products using this data must acknowledge the National Native Title Tribunal as the data source and include the NNTT disclaimer.

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.. Geospatial data portraying native title information produced by the National Native Title Tribunal may not be on-sold. Value added products using this data must acknowledge the National Native Title Tribunal as the data source and include the NNTT disclaimer.

These images are derived from the January 2002 edition of the "Magnetic Anomaly Grid of the Australian Region" (GEOCAT Record : 38820). That grid is the first integrated onshore/offshore magnetic anomaly grid for the complete Australian margin extending across 8S - 52S, 106E - 172E. The grid cell size is 0.01 degree (approx. 1 km). Earlier releases were restricted to portions of NW and SW Australia.

The Dynamic Land Cover Dataset of Australia is the first nationally consistent and thematically comprehensive land cover reference for Australia. It is the result of a collaboration between Geoscience Australia and the Australian Bureau of Agriculture and Resource Economics and Sciences, and provides a base-line for identifying and reporting on change and trends in vegetation cover and extent. The thematic map product shows the land cover of Australia for the period of March 2000 to March 2008 in 34 Internation Standards Organisation (ISO) land cover classes.

The data set provides outlines for the maximum extent of Australian geological provinces and their components, including sedimentary, igneous and metallogenic provinces, both onshore and offshore. These data were compiled as part of Geoscience Australia's integrated digital information system to provide improved accessibility and knowledge relating to the petroleum and minerals geology and prospectivity, and to provide a national stratigraphic and tectonic framework for Australia. The current dataset is not complete for Australia, and covers only offshore sedimentary provinces and a selection of sedimentary, igneous and metallogenic provinces in onshore Australia.

The Onshore Energy Systems Group has undertaken a regional study on the prospectivity of the southern Georgina Basin, and herein present a synopsis of the initial results from this multidisciplinary project. The Georgina Basin is a Neoproterozoic to Lower Devonian sedimentary basin covering 325 000 km2 of western Queensland and the Northern Territory (Dunster et al 2007, Kruse et al 2013, Munson 2014). It is a northwest-southeast-trending extensional basin where thick marine Cambrian and Ordovician sediments are preserved in its two southern depocentres, the Dulcie and Toko synclines, with a thinner succession present in the Undilla Sub-basin to the northeast. Within these depocentres, the Thorntonia Limestone and Arthur Creek Formation (Figure 1) contain potential source rocks (Ambrose et al 2001, Boreham and Ambrose 2012). Most of the southern Georgina Basin is under license for petroleum exploration, with explorers targeting the carbonate-dominated Arthur Creek Formation for both conventional and unconventional hydrocarbons. A data package that includes raw and reprocessed HyLogging data from 25 wells in the Georgina Basin was recently released (Smith and Huntington 2014). The HyLogging data map the mineralogical variations within formations and were used in conjunction with wireline log and biostratigraphic data to refine stratigraphic correlation. The HyLogging data were re-processed using a common set of mineral scalars (i.e., spectroscopic indices) to create an internally-consistent, basin-wide dataset. Other datasets, including total organic carbon (TOC) content, X-ray diffraction (XRD) measurements and biostratigraphy were also integrated with the Hylogging data. The 'hot shale' of the Arthur Creek Formation has a characteristic spectral response of decreasing albedo and an increased short wave infra-red (SWIR) aspectral response with increasing depth to the base of the Arthur Creek Formation (Figure 2). Both features appear to correlate with increasing core total gamma and TOC. These inter-relationships may be used to better characterise and identify potential source rock units in the basin. Recent biostratigraphic work has highlighted an age discrepancy in the prospective organic-rich 'hot shale' in the base of the middle Cambrian Arthur Creek Formation (Figure 1). This unit is present in the two major southern depocentres, the Dulcie and Toko synclines, where it has previously been considered as correlative. Recent results, however, suggest that the basal 'hot shale' is either significantly younger in the Toko Syncline than in the Dulcie Syncline, or represents a condensed section in the former. Middle Cambrian carbon isotope excursions have been correlated across a number of Australian basins and can be used to test correlative models across the Georgina depocentres. High resolution sampling across this middle Cambrian section has been carried out in a number of wells in the Dulcie Syncline and in the Undilla Sub-basin, where the age equivalent Inca Shale is penetrated. Carbon isotopes from organic carbon (kerogen) as well as carbon and oxygen isotope ratios of four carbonate mineral phases (calcite, ankerite, dolomite and siderite) were analysed and these data are compared with existing carbon isotope stratigraphy published from neighboring wells (Donnelly et al 1988, Lindsay et al 2005, Creveling et al 2013). Initial results corroborate the new biostratigraphic interpretation.
