The longest river in Australia is the Murray River , with a length of about 2,508 kilometres.

Quick Scoop

  • The Murray River runs through south-eastern Australia, rising in the Australian Alps and eventually emptying into the Southern (Indian) Ocean near South Australia’s coast.
  • Official Australian geographic data confirms that the Murray is the country’s longest single river at roughly 2,508 km.
  • Some sources note that if you follow the Darling River and its longest tributaries as one continuous waterway, that system is slightly longer overall, but the Murray alone is still regarded as the longest river.
