Rock-on / Barwon Bluff Marine Sanctuary

The Barwon Bluff Sanctuary extends southeast off a large rocky headland less than two kilometres south of the Barwon Heads township. The geology of Barwon Bluff is complex with the eastern side of the Sanctuary dominated by basalt reef and boulders formed from a Mt Duneed lava flow. The western side of the Sanctuary has a large intertidal sandstone platform that slopes gradually to 10m depth subtidally. The Barwon River is the major discharge into the Marine Sanctuary.

A detailed account of the geology of the Barwon Bluff can be found on the Barwon Heads website.
