Course and features
The Ourimbah Creek rises on the southern slopes of the Hunter Range, about 1.6 kilometres (0.99 mi) south of Kulnura. The river flows generally south southeast and east northeast, before reaching its mouth within Tuggerah Lake, about 4.8 kilometres (3.0 mi) southeast of Tuggerah. The river descends 304 metres (997 ft) over its 37-kilometre (23 mi) course.
The name of the river is derived from the Australian Aboriginal word meaning bora or ceremonial ground; or the word for "the sacred circle on the initiation site for investing the Oorin or belt of manhood".
