Located near the mouth of Barwon River, Barwon Bluff Marine Sanctuary protects 17ha of predominately composed of reef.
The eastern half of the reef is basalt, formed from lava flow, and is exposed to the flow of the river. The western side is old sandstone and influenced by ocean swell. On the outer edges of the reef are the wrecks of two ships.
The variation in conditions across the reef results in the presence of a huge diversity of plants and animals.
Visitors can see anything from feather stars and barnacles to rock lobsters, rays and schools of fish. Bull Kelp, sandstone arches and sponge gardens create a fascinating and complex underwater world.
