The Tarra River rises on the southern slopes of the Strzelecki Ranges, near Womerah, on the southwestern boundary of the Tarra-Bulga National Park, and flows in a highly meandering course generally east then south, joined by one minor tributary before reaching its mouth within the Corner Inlet, east of Port Albert, and emptying into Bass Strait. The river descends 238 metres (781 ft) over its 56-kilometre (35 mi) course.[6]
