Cairns, Cairns Area
The Three Sisters, located off Cairns on the Great Barrier Reef, is a series of three large bommies. The first "Gorgonian Gorge"; the second and third sisters rise to within one metre of the surface and the three metre gap between is utterly filled with schools of fusiliers and snapper. Swim-throughs, overhangs and crevices to explore, deep dives and pinnacles to swim around. A huge variety of pristine corals. Look for Barracuda, Reef sharks, Moray and Garden Eels, Lagoon Rays and Turtles.
