Publicly available groundwater data have been compiled to provide a common information base to inform environmental, resource development and regulatory decisions in the Galilee 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 Galilee Basin aquifers and their properties, including salinity, water levels, resource size, potential aquifer yield and surface water - groundwater interactions. The methods used to derive these data for all Galilee Basin aquifers in the Galilee Basin region are outlined in the associated metadata files. These are described in groundwater conceptual models (Hostetler et al., 2023). The Galilee Basin includes 3 broadly defined aquifer intervals: from deepest to shallowest, these are the Joe Joe Group, Betts Creek beds and Clematis aquifers. Compiled data have been assigned to these intervals and used to characterise groundwater systems at the basin scale. The data were 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 were used for this compilation.

Publicly available data was compiled to provide a common information base for resource development, environmental and regulatory decisions in the Galilee Basin. This data guide gives an example of how these data can be used to create the components of a workflow to identify unconventional hydrocarbon resource opportunities. The data guide is designed to support the data package that provide insights on unconventional hydrocarbon resources in the Galilee Basin. The unconventional hydrocarbon assessment for the Galilee Basin includes tight gas, shale resources (shale oil and gas) and coal seam gas (CSG) for 5 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023). The assessment captures data from well completion reports and government data sources (e.g. Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal) along with the scientific literature to inform the components required for unconventional hydrocarbons to be present. One hundred and sixty-three boreholes in the Galilee Basin were assessed, with data used to map out gross depositional environments and their geological properties relevant for unconventional hydrocarbon assessments. The data are compiled at a point in time to inform decisions on resource development activities. The data guide outlines the play-based workflow for assessing unconventional hydrocarbon resource prospectivity. Each of the elements required for a prospective unconventional hydrocarbon system is explained and mapped. These data were merged and spatially multiplied to show the relative assessment of unconventional hydrocarbon prospectivity across the basin, at both the play interval and basin scale. As an example of assessments contained within the data package, this data guide showcases the CSG prospectivity of the Betts CreekRewan Play interval.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Galilee Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Galilee Basin, including streamflow quality and quantity, inundation, and climatological data. The Galilee Basin straddles the Great Dividing Range and encompasses the headwaters of 9 major river basins, with the largest area underlying Cooper Creek, Diamantina River and Flinders River catchments. The Galilee Basin geological boundary also intersects parts of the catchment of the Burdekin River, Fitzroy River, Warrego River, Bulloo River, Paroo River and Condamine-Balonne rivers. The data on the catchments overlying the Galilee Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the Cooper Basin. This data guide illustrates the current understanding of the distribution of these key resource types within the Cooper Basin region based on trusted information sources. It provides important contextual information on the Cooper Basin and where additional details on discovered resources can be found. To date, mineral or coal deposits have not been found in the Cooper Basin, due to its depth. There are significant hydrocarbon resources found in the basin, including conventional and unconventional hydrocarbons. The Cooper Basin has been a major producer of oil and gas since the 1960s (Smith, Cassel and Evans, 2015). It is one of the largest sources of onshore hydrocarbon production in Australia. Some of the largest unconventional gas resources are contained in the basin. This is mostly basin-centred gas. The geology in the Cooper Basin is considered suitable for use in Carbon Capture and Storage (CCS) projects. The Cooper Basin and overlying Eromanga Basin contain 2 CCS projects that are currently being developed.

Across Australia, groundwater is a vital resource that supports and strengthens communities, culture, the environment and numerous industries. Movement of groundwater is complicated, taking place horizontally, vertically and across different timescales ranging from weeks to millions of years. It is affected by changes in climate, human use and geological complexities such as the type, geometry and distribution of rocks. Understanding how all these factors interact is known as a groundwater conceptual model and it is an important first step. This groundwater conceptualisation is for the shallow groundwater in the north Bowen Basin as well as surface-groundwater interactions. Figure 1 shows the location of the cross sections used to conceptualise groundwater in the north Bowen Basin region. It also shows the combined (stacked) confidence for both salinity and water levels for the shallow (<50 m below ground surface) groundwater system in the north Bowen Basin. There is no publicly available geological model for the north Bowen Basin extended region. As a result, only the shallow groundwater system is included in this conceptualisation (Wainman et al., 2023). Confidence was calculated for both salinity and water levels (Hostetler et al., 2023) and combined to show overall confidence. The level of knowledge across the extended region is medium to low. The groundwater conceptualisations show the average value of the shallow groundwater, salinity and confidence over an area of 50 km along the cross section line.

Publicly available geology data are compiled to provide a common information base for resource development, environmental and regulatory decisions in the Cooper Basin region. This data guide gives examples of how these data can be used and supports the data package that provides the existing knowledge of the key geological intervals of the Cooper Basin and the overlying Eromanga and Lake Eyre basins. The key geological intervals identified by the Trusted Environmental and Geological Information (TEGI) Program for resource assessment and groundwater system characterisation are termed play intervals and hydrostratigraphic intervals respectively. The Cooper Basin includes 7 plays, which are consolidated into 1 hydrostratigraphic interval. Overlying the Cooper Basin are 9 play intervals of the Eromanga Basin, which are consolidated into 7 hydrostratigraphic intervals and 1 Cenozoic play interval and 1 hydrostratigraphic interval for the Lake Eyre Basin. The geological groups and formations included in the play and hydrostratigraphic intervals are summarised in the stratigraphic charts of Wainman et al. (2023). Gross depositional, depth structure and thickness maps are provided with 3D model and cross-sections summarising the geology of the Cooper Basin and the overlying basins. The mapped depths and thicknesses of the key intervals are used to inform resource assessments and provide the framework for assigning groundwater data to hydrostratigraphic intervals.

Publicly available geology data are compiled to provide a common information base for resource development, environmental and regulatory decisions in the Adavale Basin region. This data guide gives examples of how these data can be used and supports the data package that provides the existing knowledge of the key geological intervals of the Adavale Basin and the overlying Galilee, Eromanga and Lake Eyre basins. The key geological intervals identified by the Trusted Environmental and Geological Information (TEGI) Program for resource assessment and groundwater system characterisation are termed play intervals and hydrostratigraphic intervals respectively. The Adavale Basin includes 8 plays, which are consolidated into 1 hydrostratigraphic interval. Overlying the Adavale Basin are 5 play intervals of the Galilee Basin, which are consolidated into 3 hydrostratigraphic intervals; 9 play intervals of the Eromanga Basin, which are consolidated into 7 hydrostratigraphic intervals; and 1 Cenozoic play interval and 1 hydrostratigraphic interval for the Lake Eyre and other Cenozoic basins. The geological groups and formations included in the plays and hydrostratigraphic intervals are summarised in the stratigraphic charts of Wainman et al. (2023a). Gross depositional, depth structure and thickness maps are provided with 3D model and cross-sections summarising the geology of the Adavale Basin and the overlying basins. The mapped depths and thicknesses of the key intervals are used to inform resource assessments and provide the framework for assigning groundwater data to hydrostratigraphic intervals.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Cooper Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Cooper Basin, including streamflow quality and quantity, inundation, and climatological data. The Cooper Basin underlies 3 surface water catchments: the Diamantina River, Cooper Creek and Bulloo River. All 3 rivers follow a similar flow pattern, with most of the run-off generated in the higher rainfall headwater areas (outside the Cooper Basin) before flowing down into extensive floodplains and ending up in terminal lake systems. The data on the catchments overlying the Cooper Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.
