The gateway to the Great Barrier Reef, Cairns is the departure port for most liveaboards in Australia. Get ready to dive with sharks, mantas and more on the largest barrier reef in the world!
On the northeast coast of Australia, Cairns offers access to the Great Barrier Reef and its rich biodiversity. You can encounter sea turtles, mantas and several species of sharks in the outer reef, including silky sharks, grey reef sharks, whale sharks and even tiger sharks. Coral gardens, bommies, pinnacles, channels and caverns make up the majority of the dive sites. While you may be able to sample the inner reefs on a day trip from Queensland, the outer reefs can only be seen by liveaboard and offer better biodiversity, healthier corals and fewer divers. Most liveaboard cruises from Cairns last 3 to 8 days, and the best time to dive the Great Barrier Reef is from June to November.
