The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

This web service delivers data from an aggregation of sources, including several Geoscience Australia databases (provinces (PROVS), mineral resources (OZMIN), energy systems (AERA, ENERGY_SYSTEMS) and water (HYDROGEOLOGY). Information is grouped based on a modified version of the Australian Bureau of Statistics (ABS) 2021 Indigenous Regions (IREG). Data covers population centres, top industries, a regional summary, groundwater resources and uses, energy production and potential across six sources and two energy storage options. Mineral production and potential covers 36 commodities that are grouped into 13 groups.

The Surface Hydrology Lines (National) dataset presents the spatial locations of surface hydrology line features and its attributes. The dataset represents the Australia's surface hydrology at a national scale. It includes natural and man-made geographic features such as: watercourses, canals, pipelines, etc. This product presents line hydrology features with full topological connectivity and flow paths for the entire continental of Australia.

The Surface Hydrology polygon (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic polygon elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia. It is intended for defining hydrological features wtih attributes.

This report presents key results from the Upper Burdekin Groundwater Project conducted as part of Exploring for the Future (EFTF)—an eight year Australian Government funded geoscience data and information acquisition program. The first four years of the Program (2016–20) aimed to better understand the potential mineral, energy and groundwater resources in northern Australia. The Upper Burdekin Groundwater Project focused on the McBride Basalt Province (MBP) and Nulla Basalt Province (NBP) in the Upper Burdekin region of North Queensland. It was undertaken as a collaborative study between Geoscience Australia and the Queensland Government. This document reports the key findings of the project, as a synthesis of the hydrogeological investigation project and includes maps and figures to display the results.

<p>This data release is part of the Federal Government’s Exploring for the Future program undertake by Geoscience Australia in collaboration with the Northern Territory Geological Survey and the Geological Survey of Queensland. It is the second staged release of data from the North Australian Geochemical Survey which sampled catchment outlet sediments at 780 sites (including duplicates) for geochemical analysis. </p> <p>The survey area was chosen to encompass the preeminent mineral provinces of Tennant Creek and Mt Isa, with the region between these two provinces providing a vast prospective exploration frontier, covered by a thin veneer of sediments and basalts, which has been overlooked for mineral exploration in the past. The data are not only useful for mineral exploration but also for agriculture and environmental management. For agriculture, this dataset can be used to assess soil fertility to maintain sustainable crop production and inform cattle grazing management over such areas as the Barkly Tablelands. The survey establishes a robust geochemical baseline dataset relevant to many environmental issues which can be utilised in development decision making into the future.</p> <p>This data release includes (1) results of the total chemical analyses of the coarse (<2 mm) fraction of sampled sediments (XRF, ICP-MS), (2) results of the aqua regia analyses of the coarse and fine fractions (<2 mm and <75 µm, respectively), and (3) results of the fire assay analysis of the coarse and fine fractions. Included is a set of georeferenced digital images of geochemical maps based on this dataset.</p>

Tennant Creek and Mt Isa are the preeminent mineral resource hubs for the Northern Territory and Queensland. The region between these two hubs is a vast prospective exploration frontier, covered by a thin veneer of sediments, which has been overlooked for exploration in the past. Regional soil sampling surveys are an excellent means of identifying the mineral potential of such regions as they can reveal what lies beneath the cover. Geoscience Australia, as part of the Federal Government’s Exploring for the Future program, undertook an extensive soil sampling survey in collaboration with the Northern Territory Geological Survey and the Geological Survey of Queensland. Catchment outlet sediment samples were collected at 776 sites (including duplicates) and analysed for their elemental composition. The data reveal areas with future potential for base metals including copper. The data are also valuable for agricultural management, allowing farmers to measure soil fertility to maintain sustainable crop production and inform cattle grazing management over the Barkly Tablelands region of the Northern Territory. This information can be used to guide safe and responsible agricultural development in the future. Further, the survey establishes robust geochemical baseline data sets relevant to many environmental issues which can be utilised in development decision making. The survey was undertaken over a period of two months utilising two helicopters from Northern Australia Helicopters based in Katherine. Samples were prepared for analysis over five months by an indigenous company supervised by Geoscience Australia staff at the Centre of Appropriate Technology in Alice Springs. Analysis of the samples was performed by Geoscience Australia in Canberra and SGS Australia mineral services in Perth. This data release includes (1) information on the sampling sites, (2) bulk sample properties (Munsell colours, pH, electrical conductivity), (3) results of the total chemical analyses of the fine (<75 m) fraction of the samples (XRF, ICP-MS) and (4) results of the partial leach analyses of the Mobile Metal Ion™ (MMI™) extractions (0–2 mm fraction, ICP-MS). Included is also a set of digital images of geochemical maps based on this dataset. This dataset is the first of a series of staged data releases from the Northern Australia Geochemical Survey. Relevant data, information and images are available through the GA website (http://www.ga.gov.au/eftf/fis/nags).
