Boomies is a reef dive off Queensland that suits beginners well, with mild currents and visibility stretching to 30 metres on a good day. Depths run from 5 to 18 metres, so you can stay shallow while you build confidence or push a little deeper as you grow comfortable. The reef attracts an impressive range of larger animals, including green, loggerhead and hawksbill turtles, eagle rays, and the occasional manta ray. Wobbegong sharks tend to rest on the reef floor, making them easy to spot without chasing anything down. Moray eels and batfish round out regular sightings. Best conditions run from June through November.
