Barren Island is the most easterly of the Keppel Islands. Visibility is usually very high because, being the furthest island from the Fitzroy River mouth, Barren has the clearest, most nutrient-free water.
Barren has about 33 coral species. With plenty of light and nutrient-free water, the conditions are ideal for branching corals.
Deep, healthy, brown beds of Acropora with white, blue and purple tips surround the island. The beds are so wide that it’s hard to anchor close to the reef without anchoring on coral, so public moorings and reef protection markers [PDF] have been installed on the north-western side.
