Water in our environment

Commonwealth Environmental Water

The Water Act 2007 establishes arrangements for the management of the water entitlements that the Commonwealth acquires. These water entitlements will be used to protect or restore environmental assets such as wetlands and streams. Further information is available at the Commonwealth environmental water homepage.


Wetlands are vital to Australia. They protect our shores from wave action, reduce the impacts of floods, absorb pollutants and provide critical habitat for animals and plants.
