Australia's Most Pristine Dive Sites: The Ribbon Reefs and the Coral Sea

Why we love it

Discover Australia’s most preserved sites with the Ribbon Reefs and the Coral Sea in this trip starting off Cairns. We love the flexible itinerary of 3, 4 or 7 days and the super friendly liveaboard team. The Ribbon Reefs have an abundance of healthy corals and marine life: colorful tropical fish and giant potato cod while the Coral Sea brings huge schools of pelagic fish and sharks. You’ll get to see Lizard Island beautiful Watson’s Bay, and maybe even fly over the great barrier reef - what a view!
