The Perth Basin is a complex geological region extending along Australia's southwest margin for about 1,300 km. It comprises sub-basins, troughs, terraces, and shelves, hosting sedimentary rocks with coal, oil, gas, and significant groundwater resources. Off the coast of Western Australia, it reaches depths of up to 4,500 m, while its onshore part extends up to 90 km inland. The basin is bounded by the Yilgarn Craton to the east, and the Carnarvon and Bremer basins to the north and south. The basin's history involves two main rifting phases in the Permian and Late Jurassic to Early Cretaceous, creating 15 sub-basins with varying sedimentary thickness due to compartmentalization and fault reactivation. The sedimentary succession mainly comprises fluviatile Permian to Early Cretaceous rocks over Archean and Proterozoic basement blocks. Differences exist between northern and southern sequences, with the south being continental and the north featuring marine deposits. During the Permian, faulting and clastic sedimentation dominated, with marine transgressions in the north and continental rocks in the south. The Triassic saw a similar pattern, with the southern succession being continental and the northern succession showing marine deposits. The Kockatea Shale became a primary hydrocarbon source. The Jurassic period witnessed marine incursions in the central basin, while the Late Jurassic experienced sea level regression and deposition of the Yarragadee Formation. The Cretaceous saw the formation of the Early Cretaceous Parmelia Group due to heavy tectonic activity. The southern basin had a marine transgression leading to the Warnbro Group's deposition with valuable groundwater resources. Post-Cretaceous, Cenozoic deposits covered the basin with varying thicknesses. Overall, the Perth Basin's geological history reveals a diverse sedimentary record with economic and resource significance.

This Surat 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 Surat Basin is a sedimentary basin with approximately 2500 m of clastic fluvial, estuarine, coastal plain, and shallow marine sedimentary rocks, including sandstone, siltstone, mudstone, and coal. Deposition occurred over six cycles from the Early Jurassic to the Cretaceous, influenced by eustatic sea-level changes. Each cycle lasted 10 to 20 million years, ending around the mid-Cretaceous. Bounded by the Auburn Arch to the northeast and the New England Orogen to the southeast, it connects to the Clarence-Moreton Basin through the Kumbarilla Ridge. The Central Fold Belt forms its southern edge, while Cenozoic uplift caused erosion in the north. The basin's architecture is influenced by pre-existing faults and folds in the underlying Bowen Basin and the nature of the basement rocks from underlying orogenic complexes. Notable features include the north-trending Mimosa Syncline and Boomi Trough, overlying the deeper Taroom Trough of the Bowen Basin and extending southwards. The Surat Basin overlies older Permian to Triassic sedimentary basins like the Bowen and Gunnedah Basins, unconformably resting on various older basement rock terranes, such as the Lachlan Orogen, New England Orogen, and Thomson Orogen. Several Palaeozoic basement highs mark its boundaries, including the Eulo-Nebine Ridge in the west and the Kumbarilla Ridge in the east. Paleogene to Neogene sediments, like those from the Glendower Formation, cover parts of the Surat Basin. Remnant pediments and Cenozoic palaeovalleys incised into the basin have added complexity to its geological history and may influence aquifer connections. Overall, the Surat Basin's geological history is characterized by millions of years of sedimentation, tectonic activity, and erosion, contributing to its geological diversity and economic significance as a source of natural resources, including coal and natural gas.

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 Eromanga 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 Eromanga Basin, part of the Great Artesian Basin (GAB) in Australia, is an extensive Mesozoic sedimentary basin filled with a mix of non-marine and marine rocks. The GAB covers about 22% of the Australian land surface, including areas in Queensland, New South Wales, South Australia, and the Northern Territory. The Eromanga Basin is the largest among the basins that form the GAB. Spanning over 1,250,000 square kilometres in central and eastern Australia, the Eromanga Basin contains rocks ranging from Jurassic to Cretaceous in age. The sedimentary deposits consist of three main basin successions: Early Jurassic to Early Cretaceous fluvial and lacustrine, Early to mid-Cretaceous marine, and Late Cretaceous fluvial-lacustrine successions. The basin's stratigraphic architecture results from a complex interplay between subsidence-controlled accommodation, sediment supply rates, and changing sediment provenance. These controls were influenced by various factors, such as intra-plate stress fields, eustatic sea-level fluctuations, and dynamic mantle-driven topography during the breakup of the Gondwana supercontinent. During the Jurassic and Early Cretaceous, regional uplift of the Australian continent led to an influx of fluvial sand-rich sediments in the western Eromanga Basin. Subsequent rapid subsidence and global high sea levels during the Early Cretaceous allowed marine sediments to spread across much of Australia, including the Eromanga Basin. The basin later returned to non-marine sedimentation during the Late Cretaceous with deposition of the Winton Formation, followed by closure due to an east-directed Late Cretaceous compressional event. This rapid deposition of the Late Cretaceous Winton Formation played a crucial role in generating and expelling hydrocarbons from various source intervals. The movement of the Australian continent significantly impacted the basin, causing most tectonic activity to occur on the southern side of a prominent keel near Innamincka in the southern half of the GAB. Additionally, variations in the mechanical properties of the sub-lithospheric mantle affected stress distribution, leading to changes in surface elevation and the expression of discharge from aquifers, potentially influencing the location and pattern of spring sites within the South Australian part of the GAB.

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 Georgina 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 Georgina Basin is a large intra-cratonic sedimentary basin in central Australia that has undergone several deformation events throughout its geological history. Its deposition began during the Neoproterozoic due to the breakup and erosion of the Rodinia Supercontinent, resulting in the broader Centralian Superbasin, encompassing the Amadeus, Georgina, Ngalia, Officer, and Savory basins. The basin's initial formation occurred as a north-west trending extensional structure in its southern part, containing thick sequences preserved in structural depo-centres such as the Toko Syncline, Dulcie Syncline, and Burke River Structural Zone. The basin unconformably overlies Proterozoic basement rocks, with its eastern boundary onlapping the Mesoproterozoic Mount Isa Province. The Georgina Basin is connected to the Daly and Wiso basins by early to middle Cambrian seaways in some areas, while in others, they are separated by basement highs like the Tomkinson, Warramunga, and Davenport provinces. The northern Georgina Basin is overlain by Mesozoic rocks of the Carpentaria Basin, and the southern basin is covered by Cenozoic deposits. The stratigraphy and rock types within the Georgina Basin include Neoproterozoic rock units in the southern parts correlated with the Centralian Superbasin, characterized by dolostone, tillite, sandstone, quartzite, siltstone, conglomerate, and shale. The basin's structure has been moderately deformed by folding and faulting, with the most significant deformation in its southern part related to the Ordovician to Carboniferous Alice Springs Orogeny. The basin's development occurred in several stages, including Neoproterozoic rifting and subsidence, tectonic activity during the Petermann Orogeny, Early Cambrian rifting, Middle to late Cambrian foreland loading and deposition, Early Ordovician minor rifting, transpression during the Alice Springs Orogeny, and a final phase of synorogenic siliclastic sedimentation in a foreland basin setting, is limited to southern depo-centres. Overall, the Georgina Basin's complex geological history has resulted in a diverse array of sedimentary rocks and structural features, making it a significant area of interest for geological studies and resource exploration in central Australia.

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 Port Phillip and Westernport basins are small, shallow sedimentary basins located in south-central Victoria, formed during the Late Cretaceous rifting of Australia and Antarctica. They share similar stratigraphy with nearby basins. The Port Phillip Basin is bounded by the Selwyn and Rowsley Faults to the east and west, while the Heath Hill Fault marks the eastern boundary of the Westernport Basin. Both basins have pre-Cenozoic basement rocks comprising folded and faulted Paleozoic metasedimentary rocks and granites from the Lachlan Fold Belt. The Port Phillip Basin's stratigraphy includes Maastrichtian to Cenozoic sedimentary units with intercalated volcanic rocks. The main depocentres are the Sorrento Graben, Ballan Graben/Lal Lal Trough, and Parwan Trough. Notable formations are the Yaloak and Werribee formations, with coal-bearing strata and marine sediments. The Westernport Basin has coastal sediments and volcanic deposits from Paleocene to Holocene. It experienced marine transgressions and regressions due to sea-level fluctuations. Fault movements in the late Pliocene and early Pleistocene formed a fault-bounded depression centered on the Koo Wee Rup Plain. The main units are the Childers Formation, Older Volcanics, Yallock Formation, Sherwood Marl, and Baxter Sandstone. Both basins have Quaternary sediments, including Pleistocene eolian sand sequences, Holocene alluvial and paludal clays, and fluvial sediments in valleys and palaeovalleys. The Port Phillip Basin contains distinct phases of terrestrial and marine deposition, while the Westernport Basin has Eocene volcanism and marine sediments. These basins are important geological features in the region, with various formations representing millions of years of geological history.

This Gippsland 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 Gippsland Basin is an asymmetrical east-trending rift structure that originated during rifting in the Late Jurassic to Early Cretaceous, as Australia and Antarctica began to separate. Over time, it developed into a continental passive margin basin, with sedimentation continuing to the present day. The basin is characterized by four main phases of tectonic evolution, interspersed with eustatic sea-level variations: initial rifting and extension, mid-Cretaceous contraction, renewed extension, and cessation of rifting in the middle Eocene. The basin's geological structures consist of mainly east to north-east trending features, with the west dominated by north-east structures due to the influence of basement trends. Major fault systems are prominent, compartmentalizing the basin into platforms and depressions separated by bedrock highs. The basin's complex stratigraphic succession reveals fluvial, deltaic, marginal marine, and open marine depositional environments. The sedimentary sequence includes terrigenous siliciclastic sediments from the Upper Cretaceous to Eocene, followed by post-rift sands, clays, coals, and limestones/marls of Oligocene to Holocene age. The Gippsland Basin's sediments are subdivided into four main stratigraphic groups: the Strzelecki, Latrobe, Seaspray, and Sale groups. The Strzelecki Group, dating from the Late Jurassic to Early Cretaceous, consists of non-marine sedimentary rocks deposited in fluvial and lacustrine environments. The Latrobe Group, from Late Cretaceous to early Oligocene, contains siliciclastic sediments deposited in various non-marine to marginal marine settings, showing significant lateral lithofacies variations. The Seaspray Group, dating from Oligocene to Pliocene, formed during a post-rift phase, characterized by marine limestone and marl units and continental clastic sediments. Lastly, the Sale Group consists of Miocene-to-Recent continental clastic sediments forming a thin veneer over the onshore portion of the basin. The Gippsland Basin also contains several basaltic lava fields, with two notable volcanic units—the Thorpdale Volcanics and Carrajung Volcanics—part of the Older Volcanics in Victoria. Overall, the Gippsland Basin's geological history and diverse sedimentary deposits make it a significant area for various geological and geophysical studies, including its hydrocarbon resources concentrated in offshore Latrobe Group reservoirs.

This Canning 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 Canning Basin, characterized by mostly Paleozoic sedimentary rocks with a maximum thickness of over 15,000 m, went through four major depositional phases from Early Ordovician to Early Cretaceous. The basin contains two main depocenters, the Fitzroy Trough-Gregory Sub-basin in the north and the Willara Sub-basin-Kidson Sub-basin in the south. The depositional history includes marine, evaporite, fluvial, deltaic, glacial, and non-marine environments. The basin's evolution began with extension and rapid subsidence in the Early Ordovician, followed by a sag stage with evaporite and playa conditions in the Late Ordovician and Silurian. The Devonian to Early Carboniferous phase involved marine, reef, fluvio-deltaic, and terrestrial sedimentation in the north and marginal marine to terrestrial systems in the south. The Late Carboniferous to mid-Triassic period saw non-marine and marine settings, including glacial environments. The basin then experienced mid-Jurassic to Early Cretaceous deposition, mainly in deltaic and non-marine environments. Throughout its history, the Canning Basin encountered multiple tectonic phases, including extension, compression, inversion, and wrench movements, leading to various depositional settings and sediment types. Around 250 petroleum wells have been drilled in the basin, with production mainly from Permo-Carboniferous sandstones and Devonian carbonates. Several proven and untested plays, such as draped bioherms, anticlinal closures, and fault blocks, provide potential for hydrocarbon exploration. Late Carboniferous and Jurassic mafic sills intersected in wells indicate additional geological complexity. Additionally, some areas of the Canning Basin are considered suitable for CO2 storage.
