Murray Mouth

The Murray Mouth is the outlet where Australia's longest river, the Murray River, meets the Southern Ocean in South Australia, within the Alexandrina Council area near Goolwa and Hindmarsh Island. Part of the Coorong National Park and Lower Lakes system, it is a dynamic sand-bar estuary between Sir Richard and Younghusband Peninsulas. Notable for its shifting channels, coastal dunes, important bird habitat and the nearby Goolwa Barrages, it is a key natural landmark at the end of the Murray-Darling Basin.

Visitors can expect a remote coastal estuary landscape where the river meets the ocean between two long sand peninsulas. The mouth is viewed from lookouts on Hindmarsh Island at Sugars Beach, from the water on boat tours departing Goolwa, or via 4WD along the beach. Expect wide sand dunes, tidal channels, seabirds and pelicans, views of the Goolwa Barrages, and interpretive signage about the Coorong ecosystem. There are no built structures at the mouth itself.
