The Great Artesian Basin (GAB) is one of the largest underground water reservoirs in the world. It underlies approximately 22% of Australia—occupying more than 1.7 million square kilometres beneath the arid and semi-arid parts of Queensland, New South Wales, South Australia and the Northern Territory.

Have your say
The draft Plan 2018 has been developed by the Australian, state and territory governments, and the Great Artesian Basin Coordinating Committee.
The draft Plan 2018 builds on the outcomes and actions of the first Strategic Management Plan agreed in 2000 and takes a principle based approach to guiding governments, industry and the community in managing this important resource together. It aims to address outstanding management issues and guide decisions that respond to emerging issues and challenges.
Water issues in the Great Artesian Basin

Water emerges naturally from the Basin through cracks in the rock encasing the water, into springs, shallow water tables or into creeks and rivers creating a permanent water source even during dry periods. Most springs and leakages occur on the edges of the Basin where water is close to the surface.
It was recognised by the early 1900s that control over GAB groundwater was inadequate and there was a reduction in water pressure and volume due to the increasing number of bores drilled that were allowed to flow uncontrolled into open drains and creeks for distribution to stock. However, even in well-maintained drains up to 95% of this water can be wasted through evaporation and seepage.
Uncontrolled flow from bores and open earth bore drains in the GAB threatens the health of important groundwater-dependent ecosystems and continued access to artesian water by pastoralists.
In addition, it has become difficult for new water users in or near the GAB to obtain access to groundwater resources.
The waste of water is causing environmental damage through:
- reduced pressure in some naturally occurring artesian springs
- encouragement of the spread of pest plants and animals
- land and water salinisation.
Economic Output of Groundwater Dependent Sectors in the Great Artesian Basin
Economic Output of Groundwater Dependent Sectors in the Great Artesian Basin Report was released by the Department of Agriculture and Water resources on 22 August 2016. The report examines the significant economic value generated by the Great Artesian Basin water resources.
Interim Great Artesian Basin Infrastructure Investment Programme
On 12 May 2017 the Australian government announced $8 million in funding for water infrastructure improvements in the Great Artesian Basin for two years to 2018-19 through an
Interim Great Artesian Basin Infrastructure Investment Program.
Great Artesian Basin Strategic Management Plan Review
The Australian and state/territory governments completed a review of the
Great Artesian Basin Strategic Management Plan 2000 in 2015.
Great Artesian Basin Sustainability Initiative
To assist in improving pressure in the Basin, the Australian, New South Wales, South Australian and Queensland governments provided funding through the
Great Artesian Basin Sustainability Initiative (GABSI).
