The Billabong Creek, a partly perennial stream of the Murray River catchment within the Murray-Darling basin, is located in the Riverina region of New South Wales, Australia.
At (with some estimates ranging up to [2]), Billabong Creek is believed to be the longest creek in the world.[3]
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 [2] over its 320km (200miles) course.
From source to mouth, the creek passes through the towns of Morven, Culcairn, Walbundrie, Rand, Jerilderie, Conargo, Wanganella, and Moulamein.
The creek has a catchment area of 791km2 and is the main present drainage line between the Murray and the Murrumbidgee rivers.[4] Alluvial deposits from the system fill a long narrow paleovalley that extends for about 150km (90miles) from Garryowen (near Holbrook) to Walla Walla.
