The designated highway finishes near Lake Nash, just east of Alpurrurulam, on the Northern Territory/Queensland border, but the track continues into Queensland for 55 km where it joins a track north to Camooweal.
These include the Burke River, flowing through the basin's major town of Boulia, the upper Georgina River itself rising in the Barkly Tableland north of Camooweal, the Ranken River rising in the extreme east of the Northern Territory beyond Tennant Creek, and the Sandover River.
