Lake Eyre Basin

Lake Eyre Basin is one of the world's largest internally draining system covering about 1.2 million square kilometres, almost one-sixth of Australia. The Lake Eyre Basin includes large parts of South Australia, the Northern Territory, Queensland and some of western New South Wales. Lake Eyre is the fifth largest terminal lake in the world.
The Lake Eyre Basin is an area of high conservation significance that supports:
  • wetlands, e.g. the Ramsar listed Coongie Lakes
  • grasslands and deserts, e.g. Simpson Desert National Park
  • rare and endangered plants, e.g. Kowari and Waddi Waddi trees (Acacia peuce)
  • rare and endangered animals, e.g. greater bilby
