The Dingo Creek rises below the Comboyne Plateau, about 1.6 kilometres (0.99 mi) southwest of Mount Gibraltar within the Killabakh Nature Reserve, north of the town of Wingham. The river flows generally west to a point east of Tapin Tops National Park, then south, joined by the Bobin and Caparra creeks, before reaching its confluence with the Manning River, at Kilawarra, west of Wingham. The river descends 679 metres (2,228 ft) over its 78 kilometres (48 mi) course.[3]
The Manning River eventually flows into the Tasman Sea through a minor delta east of Taree.[2]
