A salt breeze cuts across the marina as the Reef Experience eases away from Cairns Marlin Marina and the tropical horizon opens: endless blue, a few scattered caps of white, and the first shimmer of coral systems far offshore. Passengers settle on deck with a breakfast roll in hand while the skipper checks conditions and the crew prepares tanks and snorkel gear. By mid-morning the boat anchors at one of the outer reef sites and the water dares you with clarity that can reach 15–30 metres.
