The Wadbilliga River is a perennial stream of the Tuross River catchment that is located in the South Coast region of New South Wales, Australia.
The Wadbilliga River rises on the western slopes of Mount Wadbilliga, located within Wadbilliga National Park and part of the Kybeyan Range, within the Great Dividing Range. The river flows generally north, east northeast, east by south, and then northeast, before reaching its confluence with the Tuross River, east of the locale of Belowa. The river descends over its course.[1]
