Wallamba River, a watercourse of the Mid-Coast Council system, is located in the Mid North Coast district of New South Wales, Australia.

Course and features

Wallamba River rises on the northern slopes of Kyle Range, near the locality of Gangat. The river generally flows east and then south, joined by five minor tributaries, before reaching its confluence with the Coolongolook River at Wallis Lake; descending 271 m over its 72 km course. The river is transversed by the Pacific Highway south of Nabiac. At one stage, a riverboat milk pick-up service operated for the dairy farmers who farmed along the banks of the river. This service was discontinued in the mid-1970s due to economic reasons. Road milk tankers were then used to pick up from the farms. Water skiing and fishing is popular along the Wallamba.
