Providing Australia with solutions for water resources management while protecting and restoring our major water ecosystems.
Water: Science and Solutions for Australia provides information on the status of Australia’s water resources and their future prospects, the many values we hold for water, and the potential for using water more effectively to meet the growing demands of cities, farmers, industries, and the environment. Available for free download in multiple formats.

Overall, Australia has sufficient water resources to support its current uses, consuming six per cent of renewable water resources each year.
As a society, Australians value water highly for a range of economic, environmental, social, and cultural benefits, which at times are in conflict with each other.
Floods, droughts, and climate change are the three most important influences of climate on Australia's water resources.
Groundwater use is increasing and it is the main source of water for much of Australia’s dry interior.
Strict water quality controls are in place to protect human health and aquatic ecosystems from chemical and biological pollutants.
An extra 10 to 20 million people could be living in Australian cities by 2050, requiring more water supplies, more wastewater disposal, and greater energy use to provide these services.
Australia’s largest cities are forecast to require 1150 GL/year (or 73 per cent) above the current supply of 1505 GL/year by 2050. In addition, current supplies will probably reduce as a result of climate change, requiring additional augmentation.
Irrigated agriculture is productive and profitable, generating 50 per cent of all agricultural profit from just 0.5 per cent of agricultural land.
Aquatic and water-dependent ecosystems require surface water flows or access to ground water to survive. They include Australia’s highly valued rivers, lakes, floodplains, wetlands, and estuaries.
Mining, manufacturing, and other industries use about 20 per cent of all water consumed in Australia. They use water in cities and in some fully or over-allocated rural systems, placing them under the same pressures as other users to use water more efficiently.
There is a high level of expectation of benefits from water resources across a wide spectrum of economic, social, and environmental values.
Algal blooms are a major hazard to safe water supply as well as potentially dangerous to human, animal and fish health.
Blue-green algal blooms are a major hazard to water supplies as well as potentially dangerous to human, animal and fish health.
CSIRO water scientists have a long-standing active program building up an understanding of the complex chain of events that leads to an algal bloom, and the aftermath of toxins released into the water.
Toxins in blue-green algae may harm human and animal health if allowed to multiply to large numbers.
There are a number of options (physical, biological and Nutrient control) for management and control of blue-green algae.
