The Billabong Creek, a partly perennial stream[1] of the Murray River catchment within the Murray-Darling basin, is located in the Riverina region of New South Wales, Australia.
At 320 kilometres (with some estimates ranging up to 596 kilometres, Billabong Creek is believed to be the longest creek in the world.
Formed by the confluence of the Yarra Yarra Creek and Little Billabong Creek, Billabong Creek rises on the Great Dividing Range, north of Holbrook, and flows generally west, northwest, and west, joined by sixteen minor tributaries before reaching its confluence with the Edward River, at Moulamein. The creek descends 252 metres over its 320-kilometre course.
