Hay Reef
Protected Area
Bassett Basin
Why dive here
With 113+ marine species recorded in the area - including dugongs, grey reef sharks, humpback whales, sea turtles and tiger sharks - Hay Reef offers some of Coral Sea's richest reef diving. Water ranges 25-30°C, warmest January, February, March.
Hay Reef sits as a prominent coral structure in Australia's Coral Sea. Divers here can expect a good array of reef fish, though the larger pelagics tend to pass by rather than linger. We'd suggest this site for competent divers looking for a reliable Coral Sea experience, particularly those on a liveaboard itinerary already in the area.
