At 320 kilometres (200 mi) (with some estimates ranging up to 596 kilometres (370 mi)[4]), Billabong Creek is believed to be the longest creek in the world.[3]

Course and features

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 (827 ft)[4] over its 320 kilometres (200 mi) 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 791 square kilometres (305 sq mi) and is the main present drainage line between the Murray and the Murrumbidgee rivers.[5] Alluvial deposits from the system fill a long narrow paleovalley that extends for about 150 kilometres (93 mi) from Garryowen (near Holbrook) to Walla Walla.
