The Billabong Creek.
The longest creek in the world.
The Billabong Creek at 320 kilometres is believed to be the longest creek in the world. Formed by the confluence of the Yarra Yarra Creek and Little Billabong Creek, the Billabong Creek starts 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.
From the 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 and is the main drainage line between the Murray and the Murrumbidgee rivers. Alluvial deposits from the system fill a long narrow valley that extends for about 150 kilometres from Garryowen (near Holbrook) to Walla Walla. Here at Walla Park the creek will flow all year round. In recent history water levels have gotten to a point where you can stand with one foot on either side of the creek, however, a body of water continues to flow through the deep sand bars from pool to pool. Conversely, in 2010 and 2022 we saw record floods with water coming within metres of the Paech bridge below Morgan’s Lookout. Beyond Walbundrie the creek begins to become more seasonal in its flow and its flood plains begin to widen.
The Billabong Creek is home to many aquatic species including Golden Perch, Redfin, Murray Cod, European Carp, Silver Perch, Freshwater Yabbies, Freshwater Shrimp, turtles, water rats and more.
