The longest river in Australia is the Murray River. Spanning over 2,500 kilometers (approximately 1,550 miles), the Murray flows through southeastern Australia, originating in the Snowy Mountains and emptying into the Southern Ocean. It is an essential water source for agriculture, providing irrigation to the surrounding regions and supporting diverse ecosystems along its banks. The river has significant cultural importance for Indigenous Australians, holding historical and spiritual value. The management of the Murray River entails balancing water needs for agriculture, conservation, and recreational activities, making it a critical resource in Australia.
