Heron Island
A research-station coral cay with the Heron Bommie a few minutes from the jetty.
Heron Island is a coral cay on the southern Great Barrier Reef with a resort and a long-established marine research station, reached by boat or helicopter from Gladstone.
The Heron Bommie, a short boat ride from the jetty, is among the best-known individual dive sites on the Great Barrier Reef and was reportedly a favourite of Jacques Cousteau.
Diving is close, clear and easy, and the reef flat is accessible for snorkelling directly from the beach.
