Nambung River is a river in the wheatbelt region of Western Australia. The river lies between the town of Leeman and the Brand Highway. The river is in the main a dry creek bed, it enters a limestone cave known as Stockyard Cave at approximately and continues underground to the Indian Ocean.[1]
The Eneabba Stone Arrangement and the Nambung National Park Pinnacles are located nearby. The surrounding area is subject to the Nambung National Park Management Plan.[2][3]
Because of the relationship between the river, the unique limestone area and the surrounding environment a temporary reserve was placed over the valley of the river in 1927 to prevent guano mining.[4]
The river has a complex relationship with the coastal sand dunes and limestone area - which is clearly indicated in a map of the Nambung River basin and what are known as the Nambung wetlands.[5]
