Location: Degree Confluence 23°S 139°E is in the heart of Channel Country in western Queensland. The confluence is unmarked, and located between two branches of the Georgina River, from which the degree square takes its name. Direct access can only be gained by 4WD vehicle in dry weather while the river is passable. The closest road to the point is a dirt track that comes within 4 km to the north. The nearest settlement is Boulia, approximately 93 km to the east. The site was visited by a party of RGSQ members travelling in four 4WD vehicles from Brisbane in May, 2008.
