Abstract
<div>The Kati Thanda – Lake Eyre Basin (KT–LEB) covers about 1.2 million square kilometres of outback Australia. Although the basin is sparsely populated and relatively undeveloped it hosts nationally significant environmental and cultural heritage, including unique desert rivers, sweeping arid landscapes, and clusters of major artesian springs. The basin experiences climatic extremes that intermittently cycle between prolonged droughts and massive inland floods, with groundwater resources playing a critical role in supporting the many communities, industries, ecological systems, and thriving First Nations culture of the KT–LEB.</div><div><br></div><div>As part of Geoscience Australia’s National Groundwater Systems Project (in the Exploring for the Future Program) this report brings together contemporary data and information relevant to understanding the regional geology, hydrogeology and groundwater systems of Cenozoic rocks and sediments of the KT–LEB. This work represents the first whole-of-basin assessment into these vitally important shallow groundwater resources, which have previously received far less scientific attention than the deeper groundwater systems of the underlying Eromanga Basin (part of the Great Artesian Basin). The new knowledge and insights about the geology and hydrogeology of the basin generated by this study will benefit the many users of groundwater within the region and will help to improve sustainable management and use of groundwater resources across the KT–LEB.</div><div><br></div>

Purpose
This GA Record is the main product output from the first detailed groundwater basin inventory study undertaken as part of the National Groundwater Systems (NGS) Project under Exploring for the Future Program. Most of the data compilation and analysis work for this project was undertaken in 2022 and 2023, with writing and production in late 2023 and 2024. The purpose of the GA Record is to provide a clear written account of the work and key findings relevant to an improved basin-wide understanding of the Cenozoic Kati Thanda - Lake Eyre Basin, including the geology, hydrogeology and groundwater systems.

Lineage
<div>The data compilation, analysis and interpretation that underpins this GA Record on the Lake Eyre Basin was undertaken in 2022 and 2023. This work was undertaken as a desktop study using a range of existing geoscience datasets and analytical methods available to the project team. The draft GA Record was mostly written from April to June 2023, followed by initial internal review of the product in July and August 2023. The report was then updated in response to review comments (Sept to December 2023) and prepared for the GA approval process in January and February 2024. Final content, style and presentation updates to the product were completed in March and April 2024 in response to final approval feedback, ahead of finalising the report for publication in May 2024.</div>
