Raine Island

Raine Island is one of Australia's lesser-known scuba diving highlights, and it's ideal for sea turtle enthusiasts. This island is also the next name on the list of the best dive sites in Australia that Toplist would like to introduce to you. Raine Island, tucked away in the far north of the Great Barrier Reef, has pristine reefs and one of the world's largest gatherings of sea turtles. For over 1000 years, it has been a green sea turtle nesting site, and tens of thousands of nesting sea turtles visit each year.

While there is some hard coral in the shallows, Raine Island's walls are covered in large gorgonians, sea whips, whip corals, and black coral trees. Raine Island is home to an abundance of turtles, which can be found sleeping on the beach or cruising the walls. Sharks, particularly grey reef sharks and whitetip reef sharks, are common on Raine Island, but tiger sharks also frequent the reef to feed on sick or injured turtles. Raine Island is also home to Maori wrasse as well as pelagic fish such as barracuda, trevally, mackerel, tuna, and rainbow runners.
