Birthday Beach is a gentle drift dive that carries you along with a mild current, so you spend less energy swimming and more time watching what passes by. The water clears to between 10 and 30 metres, which makes it easy to spot marine life well before it reaches you. Depths run from 5 metres in the shallows to around 25 metres in the deeper sections, so beginners can stay comfortable while still exploring interesting terrain. Green sea turtles, loggerhead turtles, and hawksbill turtles are all regulars here, along with eagle rays, manta rays, and wobbegong sharks resting on the bottom. Keep an eye out for jellyfish, particularly in warmer months.

The clearest visibility and calmest conditions tend to fall between May and October, which also coincides with lower jellyfish activity. A guided tour is worth considering for your first visit, as a local guide will know exactly where to position you in the drift to catch the best sightings.
Access is via dive boats departing from the jetty on Heron Island. Most dive sites are within a 15-minute boat ride.
A "stinger" (jellyfish) season runs from approximately November to May. Encounters with sharks and sea snakes are possible.
