High-precision radiometric dating using Chemical Abrasion-Isotope Dilution Thermal Ionisation Mass Spectrometry (CA-IDTIMS) has allowed the recalibration of the numerical ages of Permian and Triassic spore-pollen palynozones in Australia. These changes have been significant, with some zonal boundaries in the Permian shifting by as much as six million years, and some in the Triassic by more than twice that. Most of the samples analysed came from eastern Australian coal basins (Sydney, Gunnedah, Bowen, Galilee) where abundant volcanic ash beds occur within the coal-bearing successions. The recalibrations of these widely used palynozones have implications for the dating of geological events outside the basins from where samples were obtained. Our revised dates for the Permian palynozones can now be applied to all Permian basins across Australia, including the Perth, Carnarvon, Canning and Bonaparte basins (along the western and northern continental margins), the Cooper and Galilee basins (in central Australia), and the Bowen, Gunnedah and Sydney basins (in eastern Australia). Revised regional stratigraphic frameworks are presented here for some of these basins. The impact of an improved calibration of biostratigraphic zones to the numerical timescale is broad and far-reaching. For example, the more accurate stratigraphic ages are the more closely burial history modelling will reflect the basin history, thereby providing control on the timing of kerogen maturation, and hydrocarbon expulsion and migration. These improvements can in turn be expected to translate in to improved exploration outcomes. We have initially focused on the Permian and provide preliminary results for the Triassic, but intend to expand recalibrations to include Jurassic, Cretaceous and Paleozoic successions beyond the Permian. Preliminary data indicates that significant changes to these calibrations are also likely.

Statements of existing knowledge are compiled for known mineral, coal, hydrocarbon and carbon capture and storage (CCS) resources and reserves in the Galilee Basin region. This data guide illustrates the current understanding of the distribution of these key resource types within the Galilee Basin region based on trusted information sources. It provides important contextual information on the Galilee Basin and where additional details on discovered resources can be found. The Galilee Basin region contains 6 known metallic mineral deposits, with most of these containing the critical mineral vanadium. There are 17 coal deposits found in the basin containing thermal and metallurgical coal. The primary form of coal in the deposits is thermal coal. The Galilee Basin hosts large coal tonnages, with known black coal resources of approximately 33 billion tonnes. The Galilee Basin and overlying basins are known to contain significant hydrocarbon resources. The majority of the known hydrocarbon resources are found in the Julia Creek oil shale deposits located in the Eromanga Basin above the Galilee Basin. Moderate coal seam gas (CSG) resources have also been identified in the basin; however, conventional gas resources are more limited. At this time, there are no active or planned Carbon Capture and Storage (CCS) projects in the basin.

Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the Galilee Basin. This data guide gives examples of how these data can be used to create the components of a workflow to identify geological storage of carbon dioxide (CO2) opportunities. The data guide is designed to support the data package that provide insights on the geological storage of CO2 in the Galilee Basin. The geological storage of CO2 assessment for the Galilee Basin encompasses 5 geological intervals, termed plays – these 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) to inform the 4 components required for a potential geological storage of CO2 system. One hundred and sixty-three boreholes in the Galilee Basin were used to map out gross depositional environments and their geological properties relevant for geological storage of CO2. From these datasets, the following properties were evaluated and mapped across the basin: injectivity, storage efficiency, containment and structural complexity. The data are compiled at a point in time to inform decisions on resource development opportunities. The guide outlines the play-based workflow for assessing geological storage of CO2 prospectivity. Each of the elements required for a prospective geological storage of carbon dioxide system are explained and mapped. These data were merged and spatially multiplied to show the relative assessment of geological storage of carbon dioxide prospectivity across the basin at both a play interval and basin scale. As an example of assessments contained within the data package, this data guide showcases the geological storage of CO2 prospectivity of the Betts Creek-Rewan Play interval.

Publicly available geological data in the Galilee Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region. The mineral occurrences are mostly found in the overlying basins, and they are often small and of little economic significance. There are some exceptions, such as the Lilyvale vanadium deposit found in the northern Galilee region, in the overlying Eromanga Basin. The Galilee Basin has limited potential for uranium and precious metal deposits due to relative lack of suitable formation conditions, but the depth of much of the basin makes exploration and mining difficult and expensive. There are some large coal measures found in the Galilee Basin, with 17 deposits in the Galilee and overlying Eromanga basins, containing about 38 billion tonnes of black coal. An assessment of geological storage of CO2 potential suggests the Galilee Basin Betts Creek - Rewan Play is the most prospective for storing CO2, with the highest potential around the central basin region. There are no reports of natural hydrogen in the Galilee Basin.

Publicly available baseline ecology data are compiled to provide a common information base for environment, resource development and regulatory decisions in the Galilee Basin region. This data guide captures existing knowledge of the ecosystems and environmental assets overlying the Galilee Basin. The land overlying the Galilee Basin is dominated by the Mitchell Grass Downs Interim Biogeographic Regionalisation for Australia (IBRA) bioregion and contains nearly the entire Desert Uplands bioregion. There are also smaller areas of Mulga, Brigalow Belt bioregions, Channel Country, Gulf Plains and Einasleigh Uplands bioregions. The data on the ecosystems and environmental assets overlying the Galilee Basin have been summarised in July 2021 to inform decisions on resource development activities. Key data sources are broad vegetation groups - pre-clearing and 2019 remnant - Queensland series (Queensland Government), Field Environmental Data, Australian Wetlands Database and Heritage places and lists (Department of Climate Change, Energy, the Environment and Water), and the Atlas of Living Australia.
