Realms of Land & Sea

The Murray-Darling Basin is the home of the largest river system in Australia. It is the lifeblood for eastern Australia, stretching 1,061,469 square kilometres through Queensland, New South Wales, Victoria and South Australia. The three main river systems that make up the Murray-Darling Basin include the Darling River, the Murrumbidgee River, the Lachlan River and Billabong Creek; and the Murray River itself.

As you can guess, the problems facing the river system directly affect hundreds of cities and towns, not to mention countless species of fauna and flora. 3.2 million Australians rely on the Murray Darling for their every day drinking water. The basin also provides about 41% of the country’s agriculture with water for crops like cotton, rice and wheat.
