The Towamba River is an open mature wave dominated barrier estuary or perennial river, located in the South Coast region of New South Wales, Australia.
The Towamba River rises near Coolangubra Mountain, below Mount Marshall on the eastern slopes of the South Coast Range, part of the Great Dividing Range, approximately north of Coolangubra Mountain. The river flows generally southeast and then northeast, joined by twelve tributaries including the Mataganah Creek and Wog Wog River, before reaching its mouth, emptying into Nullica Bay, within Twofold Bay, and spilling into the Tasman Sea of the South Pacific Ocean, east of Boydtown. The river descends over its course.[1]
