Abstract

<div><strong>Output Type: </strong>Exploring for the Future Extended Abstract</div><div><br></div><div><strong>Short Abstract: </strong>Australia's Great Artesian Basin (GAB) is a vital groundwater system extending across parts of Queensland, New South Wales, South Australia, and the Northern Territory, crucial for community water supplies, economic development, indigenous cultural values and groundwater dependent ecosystems. Managing GAB groundwater poses challenges due to the complex structure of the sedimentary basin, requiring a better understanding of aquifers, aquitards, and hydraulic connections at a whole GAB scale. Additionally, inconsistencies in nomenclature and subdivisions across the basin further complicate the definition and description of these strata. This study employs an integrated basin analysis workflow using new and existing data to create a 3D geological model tied to a consistent chronostratigraphic framework and State and Territory hydrostratigraphic classifications. The model refines the characteristics of 18 hydrogeological units, offering insights into aquifer boundaries and connectivity. This comprehensive approach enhances the 'whole-of-Basin' subsurface geological understanding, benefiting groundwater management, resource assessments, uncertainty risk assessment and environmental impact assessments across multiple jurisdictions and the broader resource sector (e.g., Carbone Capture and Storage and hydrogen).</div><div><br></div><div><strong>Citation: </strong>Rollet, N., Vizy, J., Norton, C.J., Hannaford, C., McPherson, A., Symington, N., Evans, T., Bradshaw, B., Szczepaniak, M., Bui Xuan Hy, A., Schoning, G. &amp; Keppel, M., 2024.
