This Eucla 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 Eucla Basin, located along Australia's southern margin, covers an extensive area of approximately 1,150,000 square kilometres, housing the world's largest grouping of onshore Cenozoic marine sediments. It stretches over 2000 km from east to west and has four main subdivisions: Scaddan Embayment, Esperance Shelf, Nullarbor Shelf, and Yalata Sub-basin offshore. The basin extends about 350 km inland from the modern southern Australian coastline and terminates around 200 km offshore where it meets sediments of the Australian-Antarctic Basin. The sedimentary succession is largely consistent throughout the entire basin. In the west, it overlaps with the Yilgarn Craton and Albany-Fraser Orogen, while in the east, the Gawler Craton and Officer Basin separate it from the Musgrave Province. The basin contains mainly Cenozoic sediments, with thicker sequences in the east due to sediment movement and regional elevation differences. The onshore Eucla Basin hosts an unfaulted sheet of sediment deposited over a south-sloping shelf during several marine transgressions. The basal units rest on a prominent unconformity above the Bight Basin, indicating a break in deposition during the separation of Australia and Antarctica. The sedimentary sequence comprises various units such as the Hampton Sandstone, Pidinga Formation, and Werillup Formation, followed by the Wilson Bluff Limestone, Abrakurrie Limestone, Nullarbor Limestone, and Roe Calcarenite. The basin's geological history is marked by significant events such as marine transgressions during the Eocene, leading to the deposition of extensive limestone formations. The Miocene saw slight tilting of the basin, exposing the Nullarbor Plain to the atmosphere and limiting further sediment deposition. During the late Miocene to Pliocene, barrier and lagoonal transgressions contributed to the formation of the Roe Calcarenite. The Pliocene period witnessed intense karstification and the development of ferricrete and silcrete, resulting in the unique modern-day topography of the region.

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.

Publicly available groundwater data have been compiled to provide a common information base to inform environmental, resource development and regulatory decisions in the Adavale Basin region. This data guide gives examples of how these data can be used. The data package included with this data guide captures existing knowledge of Adavale Basin aquifers and their properties, including salinity and water levels. The methods to derive these data for all Adavale Basin aquifers are outlined in the associated metadata files. These are described in groundwater conceptual models (Gouramanis et al., 2023). The Adavale Basin includes multiple aquifer systems that are grouped and more broadly defined as the Adavale Basin aquifers. Compiled data are assigned to these intervals and used to characterise groundwater systems at the basin scale. The data are compiled for a point in time to inform decisions on potential resource developments in the Basin. The available historical groundwater data can be used to assess the potential effects on groundwater. The data can also be used for other purposes, such as exploring unallocated groundwater resource potential. Data to January 2022 are used for this compilation.
