Up to date information about the extent and location of surface water provides all Australians with a common understanding of this valuable and increasingly scarce resource. Digital Earth Australia Waterbodies shows the wet surface area of waterbodies as estimated from satellites. It does not show depth, volume, purpose of the waterbody, nor the source of the water. Digital Earth Australia Waterbodies uses Geoscience Australia’s archive of over 30 years of Landsat satellite imagery to identify where over 300,000 waterbodies are in the Australian landscape and tells us the wet surface area within those waterbodies. It supports users to understand and manage water across Australia. For example, users can gain insights into the severity and spatial distribution of drought, or identify potential water sources for aerial firefighting during bushfires. The tool uses a water classification for every available Landsat satellite image and maps the locations of waterbodies across Australia. It provides a timeseries of wet surface area for waterbodies that are present more than 10% of the time and are larger than 2700m2 (3 Landsat pixels). The tool indicates changes in the wet surface area of waterbodies. This can be used to identify when waterbodies are increasing or decreasing in wet surface area.

This Carnarvon Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Carnarvon Basin is a large sedimentary basin covering the western and north-western coast of Western Australia, stretching over 1,000 km from Geraldton to Karratha. It is predominantly offshore, with over 80% of the basin located in water depths of up to 4,500 m. The basin is elongated north to south and connects to the Perth Basin in the south and the offshore Canning Basin in the north-east. It is underlain by Precambrian crystalline basement rocks. The Carnarvon Basin consists of two distinct parts. The southern portion comprises onshore sub-basins with mainly Paleozoic sedimentary rocks extending up to 300 km inland, while the northern section consists of offshore sub-basins containing Mesozoic, Cenozoic, and Paleozoic sequences. The geological evolution of the Southern Carnarvon Basin was shaped by multiple extensional episodes related to the breakup of Gondwana and reactivation of Archean and Proterozoic structures. The collision between Australia and Eurasia in the Mid-Miocene caused significant fault reactivation and inversion. The onshore region experienced arid conditions, leading to the formation of calcrete, followed by alluvial and eolian deposition and continued calcareous deposition offshore. The Northern Carnarvon Basin contains up to 15,000 m of sedimentary infill, primarily composed of siliciclastic deltaic to marine sediments from the Triassic to Early Cretaceous and shelf carbonates from the Mid-Cretaceous to Cenozoic. The basin is a significant hydrocarbon province, with most of the resources found within Upper Triassic, Jurassic, and Lower Cretaceous sandstone reservoirs. The basin's development occurred during four successive periods of extension and thermal subsidence, resulting in the formation of various sub-basins and structural highs. Overall, the Carnarvon Basin is a geologically complex region with a rich sedimentary history and significant hydrocarbon resources. Exploration drilling has been ongoing since 1953, with numerous wells drilled to unlock its hydrocarbon potential.

This South Australian Gulf and Yorke Cenozoic Basins dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The South Australian Gulf and Yorke Cenozoic basins consist of eleven separate basins with similar sediments. These relatively small to moderate-sized basins overlies older rocks from the Permian, Cambrian, or Precambrian periods and are often bounded by north-trending faults or basement highs. The largest basins, Torrens, Pirie, and Saint Vincent, share boundaries. The Torrens and Pirie basins are fault-bounded structural depressions linked to the Torrens Hinge Zone, while the Saint Vincent basin is a fault-bounded intra-cratonic graben. Smaller isolated basins include Carribie and Para Wurlie near the Yorke Peninsula, and Willochra and Walloway in the southern Flinders Ranges. The Barossa Basin, Hindmarsh Tiers, Myponga, and Meadows basins are in the Adelaide region. These basins resulted from tectonic movements during the Eocene Australian-Antarctic separation, with many forming in the late Oligocene. Sediment deposition occurred during the Oligocene to Holocene, with various environments influenced by marine transgressions and regressions. The well-studied Saint Vincent Basin contains diverse sediments deposited in fluvial, alluvial, deltaic, swamp, marine, littoral, beach, and colluvial settings, with over 30 major shoreline migrations. Eocene deposition formed fluvio-deltaic lignite and sand deposits, before transitioning to deeper marine settings. The Oligocene and Miocene saw limestone, calcarenite, and clay deposition, overlain by Pliocene marine sands and limestones. The uppermost sequences include interbedded Pliocene to Pleistocene limestone, sand, gravel, and clay, as well as Pleistocene clay with minor sand lenses, and Holocene to modern coastal deposits. The sediment thickness varies from less than 50 m to approximately 600 m, with the Saint Vincent Basin having the most substantial infill. Some basins were previously connected to the Saint Vincent Basin's marine depositional systems but later separated due to tectonic movements.

This Bowen Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Bowen Basin is part of the Sydney–Gunnedah–Bowen basin system and contains up to 10,000 m of continental and shallow marine sedimentary rocks, including substantial deposits of black coal. The basin's evolution has been influenced by tectonic processes initiated by the New England Orogen, commencing with a phase of mechanical extension, and later evolving to a back-arc setting associated with a convergent plate margin. Three main phases of basin development have been identified; 1) Early Permian: Characterized by mechanical extension, half-graben development, thick volcanic units and fluvio-lacustrine sediments and coal deposits. 2) Mid Permian: A thermal relaxation event led to the deposition of marine and fluvio-deltaic sediments, ending with a regional unconformity. 3) Late Permian and Triassic: Foreland loading created a foreland basin setting with various depositional environments and sediment types, including included fluvial, marginal marine, deltaic and marine sediments along with some coal deposits in the late Permian, and fluvial and lacustrine sediments in the Triassic. Late Permian peat swamps led to the formation of extensive coal seams dominating the Blackwater Group. In the Triassic, fluvial and lacustrine deposition associated with foreland loading formed the Rewan Formation, Clematis Sandstone Group, and Moolayember Formation. The basin is a significant coal-bearing region with over 100 hydrocarbon accumulations, of which about one third are producing fields. The Surat Basin overlies the southern Bowen Basin and contains varied sedimentary assemblages hosting regional-scale aquifer systems. Cenozoic cover to the Bowen Basin includes a variety of sedimentary and volcanic rock units. Palaeogene and Neogene sediments mainly form discontinuous units across the basin. Three of these units are associated with small eponymous Cenozoic basins (the Duaringa, Emerald and Biloela basins). Unnamed sedimentary cover includes Quaternary alluvium, colluvium, lacustrine and estuarine deposits; Palaeogene-Neogene alluvium, sand plains, and duricrusts. There are also various Cenozoic intraplate volcanics across the Bowen Basin, including central volcanic- and lava-field provinces.

This Bonaparte Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Bonaparte Basin is a large sedimentary basin off the north-west coast of Australia, encompassing both offshore and onshore areas. It has undergone multiple phases of extension, deposition, and tectonic inversion from the Paleozoic to Cenozoic periods. The Petrel Sub-basin, situated on the eastern margin, exhibits a north-west trending graben/syncline and exposes lower Paleozoic rocks onshore while transitioning to upper Paleozoic, Mesozoic, and Cenozoic sediments offshore. Onshore, the basin's geological structures reflect two dominant regimes: north to north-north-east trending Proterozoic basement structures associated with the Halls Creek Mobile Zone, and north-north-west trending basin structures linked to the rifting and later compressional reactivation of the Petrel Sub-basin. The Petrel Sub-basin has experienced growth and tectonic inversion since the Paleozoic, marked by volcanic activity, deposition of clastics and carbonates, and extension events. During the Devonian, extension occurred along faults in the Ningbing Range, leading to the deposition of clastics and carbonates. The Carboniferous to Permian period witnessed offshore extension associated with the Westralian Superbasin initiation, while onshore deposition continued in shallow marine and transitional environments. Thermal subsidence diminished in the Early Permian, and subsequent compression in the mid-Triassic to Early Jurassic reactivated faults, resulting in inversion anticlines and monoclines. After the Early Jurassic, the sub-basin experienced slow sag with predominantly offshore deposition. Post-Cretaceous deformation caused subsidence, and an Early Cretaceous transgression led to shallow marine conditions and the deposition of chert, claystone, and mudstones. Mid-Miocene to Recent compression, related to continental collision, reactivated faults and caused localized flexure. The stratigraphy of the onshore Bonaparte Basin is divided into Cambro-Ordovician and Middle Devonian to Early Permian sections. Studies have provided insights into the basin's stratigraphy, with an update to the Permo-Carboniferous succession based on seismic interpretation, borehole data integration, field validation, and paleontological information. However, biostratigraphic subdivision of the Carboniferous section remains challenging due to poorly constrained species definitions, leading to discrepancies in the application of biozonations.

This Ord Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Ord Basin, an intracratonic sedimentary basin, covers about 8000 square kilometres on the border of Western Australia and the Northern Territory. It was once part of the extensive Centralian Superbasin, which deposited sediments across central and northern Australia from the Proterozoic to early Palaeozoic era. The Ord Basin comprises three synclines with up to 2500 m of Cambrian and Devonian sedimentary rocks, separated by major faults and Proterozoic basement highs. The basin's northern boundary is defined by the Halls Rewards Fault and Proterozoic basement rocks, separating it from the Bonaparte Basin. The western edge overlies rocks of the Paleoproterozoic Halls Creek Orogen, while the eastern margin is separated from the Wiso Basin by volcanic Kalkarindji Province and Proterozoic Birrindudu and Victoria basins. The southern boundary is formed by the Negri Fault and Proterozoic basement highs. The depositional history of the Ord Basin can be divided into three phases. The early Cambrian witnessed extensive basaltic volcanism, forming the Antrim Plateau Volcanics. Subsequently, the Cambrian marine transgression deposited carbonates and clastic rocks of the Goose Hole Group, including the Elder and Negri Subgroups. The Late Devonian saw the deposition of continental sandstones and conglomerates of the Mahony Group. Throughout the basin's evolution, tectonic movements and erosional processes shaped its present configuration. The Alice Springs Orogeny (450 to 300 Ma) caused deformation and landscape changes, resulting in the deposition of the Mahony Group. Periodic reactivation of growth faults in the underlying Birrindudu Basin and subsequent erosion contributed to the basin's current structure. The Ord Basin's three synclines are the Hardman Syncline (southern and largest), the Rosewood Syncline (central), and the Argyle Syncline (northern). The Hardman Syncline holds the full succession of basin strata.

This Arafura Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Arafura Basin is a large intracratonic sedimentary basin along the northern continental margin of Australia. Over 90% of the basin occurs offshore in relatively shallow marine waters of the Arafura Sea, with the basin extending northwards beyond Australia's territorial claim. The southern part of the basin is onshore in northern Arnhem Land. Older Paleo- to Mesoproterozoic rocks of the northern Macarthur Basin underlie most of the onshore basin, whereas Mesozoic and Cenozoic sediments of the Money Shoal Basin unconformably overlie the offshore basin. The sedimentary record of the Arafura Basin spans greater than 250 million years, from the late Neoproterozoic to the early Permian. However, subsidence was episodic and restricted to four main phases of regional subsidence interspersed with relatively long periods of tectonic quiescence. Consequently, the entire sedimentary succession of the basin is relatively structurally conformable. The oldest rocks are the Neoproterozoic to Cambrian Wessel Group. These are overlain by the Middle Cambrian to early Ordovician Goulburn Group, followed by the Late Devonian Arafura Group. The uppermost sequence is Late Carboniferous to early Permian (an equivalent of the Kulshill Group from the neighbouring Bonaparte Basin). The sedimentary rocks of the Arafura Basin are clastic-dominated and include sandstone, shale, limestone, dolostone and minor coal and glacial deposits. Most of the Arafura Basin formed within shallow marine environments, with evidence for fluvial conditions largely restricted to the Carboniferous to Permian rocks. There are no detailed basin-scale studies on the hydrogeology and groundwater systems of the Arafura Basin. Previous hydrogeological investigations by the Northern Territory Government during the 1980s and 1990s focused on groundwater supplies for remote communities such as Maningrida, Galiwinku and Millingimbi. Groundwater for these communities is sourced from fractured rock sandstone aquifers, most likely units of the Arafura Basin such as the Marchinbar Sandstone and Elcho Island Formation of the Wessel Group. The aquifers are fractured and extensively weathered up to 100 metres below surface.

This Karumba Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Karumba Basin is a shallow geological basin in Queensland, Australia, composed of sedimentary rocks and unconsolidated sediments that cover the Mesozoic Carpentaria Basin. Deposition started during the Late Cretaceous to Early Paleocene and has continued into the Holocene. The basin extends from western Cape York Peninsula into the Gulf of Carpentaria, where it connects with Cenozoic sediment deposits in Papua New Guinea. Although the sediments in both areas share lithostratigraphic and biostratigraphic similarities, their tectonic histories differ. The basin's structural geology is relatively uniform, with a significant downwarp known as the Gilbert-Mitchell Trough in Cape York Peninsula and another depocenter offshore in the Gulf of Carpentaria. The depositional history and stratigraphy of the Karumba Basin can be divided into three cycles of deposition, erosion, weathering, and the formation of stratigraphic units. The earliest cycle (the Bulimba Cycle) began in the Late Cretaceous to Early Paleocene, with episodes of significant uplift along the eastern margins of the basin. This resulted in the deposition of the Bulimba Formation and the Weipa Beds, primarily consisting of claystone, sandstone, conglomerate, and siltstone with minor coal layers. This cycle was followed by a period of planation and deep weathering, creating the Aurukun Surface. The second cycle (the Wyaaba Cycle) was initiated by large-scale earth movements along the Great Dividing Ranges, forming much of the eastern boundary of the Karumba Basin, and leading to the formation of the Wyaaba beds and other equivalent units. These beds consist mainly of fluvial to paralic clay-rich sandstone, conglomerate, siltstone, and claystone. In the south-west, Oligocene to Pliocene limestone deposits also formed in lacustrine settings, and were sourced from and deposited upon the underlying Georgina Basin. The cycle ended with ensuing periods of erosion and weathering and the development of the Pliocene Kendall Surface, as well as widespread basaltic volcanism. The final cycle (the Claraville Cycle) started in the Pliocene and continues to the present. It has experienced several episodes of uplift and deposition controlled by sea level change, climate variability and volcanism in the south. The Claraville beds are unconsolidated sediments, chiefly comprised of clayey quartzose sand and mud with minor gravels, reaching approximately 148 m thickness offshore, and approximately 70 m onshore. As this cycle is still ongoing, no terminal surface has been formed, and most units consist of unconsolidated surficial sediments.

This Otway Basin dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus. The Otway Basin is an elongated sedimentary basin located on the south-east continental margin of Australia. Covering approximately 150,000 square kilometres and stretching about 500 km from South Australia's Cape Jaffa to Victoria's Port Phillip Bay and Tasmania's north-west, most of the basin is offshore, with a smaller portion onshore. Geological studies of the Otway Basin have primarily focused on its hydrocarbon prospectivity, examining thick Cretaceous aged rocks both onshore and offshore. However, the shallower onshore sedimentary units are more relevant from a groundwater perspective. The basin's formation began with rifting between the Australian and Antarctic plates during the Late Jurassic, leading to regional subsidence and the development of the elongated sedimentary basin. Following the Cretaceous plate breakup, a passive margin basin formed, which subsequently underwent basin inversion, reverse faulting, and folding, interspersed with extensional periods and normal faulting. This complex evolution, combined with sea level variations and volcanic activity, resulted in numerous sedimentary cycles. The sedimentary succession in the basin comprises non-marine sediments and volcanic rocks from the Jurassic and early Cretaceous, with a period of tectonic compression interrupting sedimentation during the mid-Cretaceous. The late Cretaceous and Cenozoic sedimentary and volcanic rocks form the primary groundwater-bearing aquifers of the basin, with various sedimentary environments developing in the Neogene and Quaternary. The basin's structural geology is intricate, with numerous basement highs, sub-basins, troughs, and embayments. Fault systems are prevalent, separating tectonic blocks and potentially influencing groundwater flow, offering conduits for inter-aquifer connectivity. Overall, the Otway Basin's geological history has shaped its hydrocarbon potential and groundwater resources, making it an essential area for ongoing research and exploration in Australia's geological landscape.
