At the mouth of the Barwon River near Barwon Heads, this 17-hectare marine sanctuary protects a remarkable mosaic of basalt and sandstone reefs teeming with life. Snorkellers can drift over colourful sponge gardens, swim through towering kelp forests of Crayweed and Bull Kelp, and explore shallow rock platforms packed with anemones, seastars, and molluscs. The sheltered eastern side offers calm conditions influenced by tidal currents, while the western side catches Bass Strait swells. Look for the remains of the 1853 shipwreck Earl of Charlemont on the outer reef edge — all within a compact, easily accessible site.

Moderate risk: Cliff Instability
Recent rockfall events along the Bluff cliffs. Stay clear of cliff bases and areas of fallen rock debris.
Moderate risk: Swell Exposure (West Side)
The western side of the reef is exposed to persistent high-energy south-westerly swells from Bass Strait, creating rough conditions.
Low risk: Strong Tidal Currents
Tidal currents and Barwon River flow influence the eastern side of the reef, with tidal variation up to 2.1 metres on spring tides.
Low risk: Slippery Rock Platforms
Intertidal calcarenite and basalt reef platforms can be extremely slippery, especially when wet with algae.
