Working together to deliver the next generation of Australia’s water infrastructure
Do you have an idea that could help increase Australia’s water security?
Australia is a country built on good ideas. The ideas we have to capture, store and distribute water now and into the future will be central to our efforts to grow agriculture, increase water security and build resilience to drought.
Some of the most valuable perspectives come from the places and people that are most directly impacted by a changing climate. This is especially true of Australia’s regions, where drought and a changing climate have a direct impact on water security.
Sharing your views with the National Water Grid Authority (NWGA) will help us develop a better understanding of the water security challenges facing regional Australia, and some of the solutions that can be considered to address those challenges.

You can also share your water infrastructure ideas with state or territory ministers.

Moving water over long distances
Proposals to move water over long distances from wet to dry areas of Australia are popular and often suggested to the NWGA. Moving water over long distances is generally costly; factors such as construction and operating costs, technical feasibilities and environmental regulation all need to be considered. The NWGA is looking at these issues in the context of its Science Program and Investment Framework.
The Bradfield Scheme and variations
Work is underway through the NWGA’s Science Program to review the Bradfield Scheme, and variations of the original idea. While this idea was first proposed in 1938, it is important we review it using the best available contemporary science, drawing on the expertise of Australia’s leading science agencies, CSIRO, the Bureau of Meteorology and Geoscience Australia as required.
The NWGA’s Science Program is considering several options to secure Australia’s future water needs, including desalination. Desalination already supplies urban water to some of our major cities, and smaller centres, but its potential to provide fresh water for agricultural use needs further consideration. Technical feasibility, and economic and environmental impacts are some of the factors that will need to be considered.
Directing water inland to Lake Eyre
Proposals to increase permanent water surfaces in inland Australia by diverting water to the Kati Thanda-Lake Eyre Basin (the Lake Eyre Basin) using canals, channels or pipelines, have been popular to date. Climate modelling by the Bureau of Meteorology and CSIRO has found no evidence to support the idea that maintaining Lake Eyre as a permanent water body would result in widespread climate amelioration or increase rainfall.
