Thetford Reef

Thetford Reef, located near Cairns, spans nearly 2 kilometers and features scattered coral heads along its leeward edge, offering a variety of dive sites. Divers should be cautious with navigation as it is easy to become disoriented and drift away from the boat without dive time remaining, so bringing a safety sausage is advisable. The sandy floors between the numerous coral bommies are adorned with smaller coral patches and abundant blue staghorn thickets. Among these, divers can find giant clams, butterflyfish, rabbitfish, damselfish, and angelfish.
