Water management in Australia is a complex process. It includes:
- water pricing and economic regulation
- water planning and management
- water markets
- water supply and services
- water quality management.
There are different approaches in each State and Territory. This section is provided for general information purposes only. For details on water management arrangements, please refer to relevant jurisdiction links. Water governance information is also available on the National Water Commission website .
There are five levels of water management in Australia:
National and cross-border management
The national/cross-border arrangements table on the national rules page outlines many of the key pieces of legislation which govern national and cross-border water management in Australia.
The table below contains some additional cross-border river basin water management arrangements.
|Cross-border arrangement||Type of arrangement||Summary|
