The Minnamurra River, an open mature wave dominated barrier estuary,[1] is located in the Illawarra region of New South Wales, Australia.

The village of Minnamurra is near the mouth of the river, where it flows into the Pacific Ocean.

Minnamurra River rises within the Budderoo National Park on the eastern slopes of the Illawarra escarpment, west of the village of Jamberoo and north of Missingham Pass, and flows generally east, descending the 100 metres (330 ft) Minamurra Falls.

The name Minnamurra is derived from the Aboriginal word of Meme Mora,[3] meaning "river of many fish".

[4] In 1893, four adults and three children were drowned whilst rowing a small boat near the mouth of the Minnamurra River.
