The Queensborough River is a perennial river of the Snowy River catchment, located in the Alpine regions of the Australian states of Victoria and New South Wales.
The Queensborough River rises on the Errinundra Plateau, approximately north northwest of Combienbar, in East Gippsland, Victoria. The river flows generally north northwest and north northeast, joined by one minor tributary, before joining with the Bendoc River to form the Little Plains River approximately south southwest of Craigie, north of the Black-Allan Line that forms part of the border between Victoria and New South Wales. The river descends over its 19km (12miles) course.[2]
