Coral Garden sits off Queensland's coast and combines a wall, reef, and gentle drift dive into one accessible site. Depths run from 10 to 25 metres in the deeper sections, and visibility regularly reaches 15 to 30 metres, so you can see a long way even as a newer diver. The mild current does most of the work, carrying you along the reef without much effort. Keep an eye out for turtles resting on the reef, giant clams, and moray eels tucked into crevices. Nudibranchs reward slower, closer inspection, while reef sharks and barracuda cruise the mid-water. Lionfish and coral trout are common sightings along the wall. Manta rays pass through periodically. Watch where you place your hands near the coral, stay aware of jellyfish, and give all marine life plenty of space.
