The Seas and Submerged Lands Act (SSLA) 1973 is the Australian legislation that provides the domestic legal framework for Australia to declare its international offshore maritime zones, as provided for by the United Nations Convention on the Law of the Sea (UNCLOS) to which Australia is a party. Proclamations under the SSLA establish the territorial sea baseline, the territorial sea, the contiguous zone, the exclusive economic zone and the continental shelf. This service depicts official spatial representation of these proclamations. The service includes feature layers: Normal and Straight baselines limits and locations; Contiguous Zone and limit; Territorial Sea Zone and limit; Exclusive Economic Zone (EEZ), limits and locations; Continental Shelf limit and locations.

This service is produced specifically for the Northern Australia Project and may be removed or changes without notice. This web service shows land tenure in Western Australia and Queensland north of the Tropic of Capricorn and the whole of Northern Territory. This service uses PSMA 2015 land tenure data for Western Australia, and PSMA August 2016 for Northern Territory and Queensland.

This service provides access to hydrochemistry data (groundwater and surface water analyses) obtained from water samples collected from Australian water bores or field sites.

This service delivers data from Geoscience Australia's Petroleum Systems database, a compilation of information from summary reports on petroleum systems by basin across Australia, integrated with data from other Geoscience Australia databases including provinces, stratigraphy and boreholes. The data provided by this service is intended for use in the Petroleum Systems Summary tool on the Geoscience Australia Portal. The tool's aim is to provide high-level information of the current understanding of key petroleum systems for areas of interest and assist geological studies by summarising and interpreting key datasets related to conventional and unconventional hydrocarbon exploration. Each petroleum systems summary includes a synopsis of the basin and key figures detailing the basin outline, major structural components, data availability, petroleum systems events chart and stratigraphy, and a précis of the key elements of source, reservoir and seal.

This web service provides access to gridded data produced by Geoscience Australia from studies of Australian groundwater and hydrogeological systems.

This web service provides access to groundwater raster products for the Upper Burdekin region, including: inferred relative groundwater recharge potential derived from weightings assigned to qualitative estimates of relative permeability based on mapped soil type and surface geology; Normalised Difference Vegetation Index (NDVI) used to map vegetation with potential access to groundwater in the basalt provinces, and; base surfaces of basalt inferred from sparse available data.

This service contains the NATMAP 1:250,000 scale maps, from the NATMAP Digital Maps 2008 DVD. The large scale single mosaic map covers the entire continent, and is based on the Geocentric Datum of Australia 1994 (GDA94) geographic projection. The maps have been revised using a variety of data sources, including SPOT and Landsat satellite imagery, other government agency information and data supplied by private companies and individuals. The original DVD was produced by Geoscience Australia's National Mapping Division and its predecessor, the Australian Surveying and Land Information Group (AUSLIG).

Australia - Offshore Minerals Act 1994 - Mineral Blocks - epoch 2014a. This service displays the Australian Mineral Blocks - Aligned with the current Australian Maritime Boundary Dataset. Refer to the metadata of the geodatabase for a detailed abstract relating to the data.

This OGC conformant web service delivers data from Geoscience Australia's Boreholes database (borehole header and directional survey data) and associated geological observations (lithostratigraphic data). The data includes records of boreholes drilled by Geoscience Australia and its predecessor organisations (BMR, AGSO), all boreholes drilled in Australian Commonwealth offshore marine jurisdictions, and a selection of onshore boreholes drilled by government and private entities. Where possible this service conforms to the GeoSciML v4.1 data transfer standard. Geoscience Australia is not a reporting or regulatory authority for borehole drilling. Borehole information in Geoscience Australia's Boreholes database is sourced from various regulatory authorities in the States, Northern Territory and Commonwealth governments for Geoscience Australia research purposes. Where Geoscience Australia is not the custodian of borehole data provided in this web service, the custodian agency provided with the data should be consulted as the authoritative source.

World Bathymetry Base Map tile cache. The service includes world bathymetry data, and ocean, country, population and natural features. The information was derived from various sources, including Natural Earth and National Geophysical Data Center (NGDC) ETOPO2 Global 2 Elevations from the September 2001 data. The service contains layer scale dependencies.
