Geoscience Australia is investing in improved access to groundwater data to support informed water management decision-making for the benefit of all Australians. In 2023, we released the National Hydrogeological Inventory (NHI) to provide a nation-wide overview of Australia’s major hydrogeological provinces. The initial release of the NHI, accessible via our online Data Delivery Portal, provides access to a wealth of data and summary information about the hydrogeology and groundwater systems of the nation’s 42 major hydrogeological provinces. This content is further enhanced by valuable contextual information about the people, communities, industries, and environmental assets that rely on groundwater within these provinces. Complementing the national-scale overview were two regional hydrogeological investigations of trans-jurisdictional aquifers of the Kati Thanda - Lake Eyre Basin in central Australia, and the South Nicholson - Georgina Basin in northern Australia. These in-depth studies included new data analysis and integration of hydrogeological, hydrochemical, geophysical and other datasets to develop improved conceptual understanding of groundwater flow systems and related processes and interactions. Under the recently announced Resourcing Australia's Prosperity Initiative, Geoscience Australia is embarking on the next phase of development to improve the NHI. Novel updates and modifications currently planned include: 1. Enhanced visualisations via the portal interface; 2. Addition of new data and narrative content for province reports; and 3. Further detailed hydrogeological studies in priority regions. As we continue to grow the NHI and its long-term vision as a national compendium of hydrogeological knowledge, we welcome input and ideas from the Australian and international hydrogeological communities.
