Billabong Creek is widely regarded as the longest creek in the world, stretching approximately 320 kilometres (200 miles) through the Riverina region of New South Wales, Australia. Rising on the Great Dividing Range north of Holbrook at an elevation of 322 metres, it is formed by the confluence of Yarra Yarra Creek and Little Billabong Creek before flowing generally west and northwest, descending 252 metres over its course and ultimately joining the Edward River at Moulamein. The creek passes through or near several towns including Morven, Culcairn, Walbundrie, Rand, Jerilderie, Conargo, Wanganella, and Moulamein, and is part of the broader Murray-Darling Basin system — one of Australia's most significant inland waterway networks. As a partly perennial stream within the Murray River catchment, Billabong Creek offers a diverse and rewarding fishing experience across its vast length, drawing both local anglers and visitors to the Riverina region.
