Groundwater is critical to Australia’s future economic development and is the only reliable water source for many regional and rural communities. It also sustains environmental and cultural assets including springs and groundwater-dependent ecosystems. The demand for groundwater in Australia is expected to increase with population growth, economic development and climate change. Geoscience Australia, in partnership with Commonwealth, State and Territory governments is delivering national and regional groundwater investigations through the Exploring for the Future (EFTF) Program to support water management decisions.
Geoscience Australia’s groundwater studies apply innovative geoscience tools and robust geoscientific workflows to increase knowledge and understanding of groundwater systems and assessment of groundwater resource potential for economies, communities and the environment. Through integrating geological and hydrogeological data, airborne electromagnetic and ground-based geophysical, hydrogeochemical and remote sensing data, we have developed new geological and hydrogeological conceptual models and identified potential managed aquifer recharge sites in a number of areas across Northern Australia.
The EFTF program is focussed on improving our understanding of Australia's groundwater through a National Groundwater Systems project as well as two regional-scale groundwater investigations in Southern Australia. We are commencing an inventory of Australia’s groundwater systems in onshore basins that includes a compilation and broad interpretation of hydrogeological information. This is the basis for the collation and curation of nationally seamless groundwater information to support informed decision making and water resource coordination across jurisdictions.
