The Great Artesian Basin is one of the worlds largest groundwater systems. It’s absolutely huge, It covers about 20 percent of Australia’s land mass and it contains a vast amount of water. Water from the Great Artesian Basin is often the only reliable source of drinking water for towns and also for property. It’s used for industry, for providing stock water to cattle and sheep, also for mining. it’s also an important source of water for some inland rivers and for springs, so there’s a lot of unique ecosystems that have developed around these springs that are sourced from the Great Artesian Basin. This Atlas pulls together all the geological information we have on the Great Artesian Basin and condenses it into 55 beautiful maps. These maps are a much more accessible way for people to understand how the Great Artesian Basin works. For specialists like me, but also for water managers, land owners, industry, for researchers, and for the wider public. The atlas provides a greater understanding of Australia’s largest groundwater resource. It will enable us to make better decisions about allocating groundwater, to ensure the sustainability of the resource and everything that depends on it.
