Abstract
<div>This report brings together data and information relevant to understanding the regional geology, hydrogeology, and groundwater systems of the South Nicholson – Georgina (SNG) region in the Northern Territory and Queensland. This integrated, basin-scale hydrogeological assessment is part of Geoscience Australia’s National Groundwater Systems project in the Exploring for the Future program. While the northern Georgina Basin has been at the centre of recent investigations as part of studies into the underlying Beetaloo Sub-basin, no regional groundwater assessments have focused on central and southern parts of the Georgina Basin since the 1970s. Similarly, there has been no regional-scale hydrogeological investigation of the deeper South Nicholson Basin, although the paucity of groundwater data limited detailed assessment of the hydrogeology of this basin. This comprehensive desktop study has integrated numerous geoscience and hydrogeological datasets to develop a new whole-of-basin conceptualisation of groundwater flow systems and recharge and discharge processes within the regional unconfined aquifers of the Georgina Basin.</div><div><br></div><div>Key outputs arising from this study include: (1) the development of a hydrostratigraphic framework for the region, incorporating improved aquifer attribution for over 5,000 bores; and (2) publicly available basin-scale groundwater GIS data layers and maps, including a regional watertable map for the whole Georgina Basin. This regional assessment provides new insights into the hydrogeological characteristics and groundwater flow dynamics within the Georgina Basin, which can aid in the sustainable management of groundwater for current and future users reliant on this critical water resource.</div><div><br></div><div><br></div>

Purpose
This GA Record provides an account of work undertaken and key findings from a new regional-scale study of the hydrogeology and groundwater systems of the South Nicholson and Georgina basins region in the Northern Territory and Queensland. The record has been developed to present new data, information and knowledge of groundwater systems in this large region of northern Australia. This product is an important deliverable under Module 1 of the National Groundwater Systems Project in the Exploring for the Future Program and was completed in July 2024.

Lineage
<div>This product was developed as part of an original hydrogeological research investigation undertaken as part of the Exploring for the Future Program. The work presented in the report includes relevant information compiled and synthesised from review of existing scientific and technical data and published literature. In addition, the report includes the results of new data analysis and interpretation of existing datasets, including hydrostratigraphy, hydrochemistry, groundwater flow systems, and airborne electromagnetics.</div><div><br></div>
