The Tuross River, an open semi-mature wave dominated barrier estuary or perennial stream, is located in the South Coast region of New South Wales, Australia.
Tuross River rises of the eastern slopes of the Kybeyan Range, part of the Great Dividing Range, below Mount Kydra on the western edge of Wadbilliga National Park, not far from Cooma. The river flows generally north, east and northeast, joined by fourteen tributaries including the Back River and Wadbilliga rivers, before spilling into Tuross Lake and reaching its mouth at the Tasman Sea of the South Pacific Ocean at Tuross Head. The river descends 1,170 metres over its 147 kilometres course.
The catchment area of the river is 1,814 square kilometres with a volume of 18,208 megalitres over a surface area of 15.5 square kilometres, at an average depth of 1.2 metres
