The mighty Fitzroy River is a defining waterway of the Kimberley region, flowing 525 kilometres from the Durack Range to discharge into King Sound near the historic port town of Derby. This is a river of extremes, with a vast catchment area of 90,000 square kilometres. During the wet season, it transforms into one of the world's largest rivers by volume, capable of pushing a staggering 30,000 cubic metres of water per second over the bridge at Fitzroy Crossing. In the dry season, the flow subsides dramatically, leaving a series of permanent waterholes along the river and its expansive floodplains, which become critical refuges for fish and wildlife. The river flows through the stunning Geikie Gorge National Park and is renowned as a premier fishing destination, particularly for iconic Australian sportfish. Access to much of the river is via pastoral stations, requiring prior permission, while public access is available at key towns and the national park.
