27km offshore from Cairns. This small rainforest-clad coral cay is surrounded by coral reefs. It is one of the most accessible and popular islands on the Great Barrier Reef. Green Island is the most popular destination on the Great Barrier Reef. This 12ha island is a true coral cay formed over thousands of years by the build-up of sand and coral rubble deposited on the calm side of a platform reef. The island is covered in tropical vine forest which supports a diversity of birds and insects. The surrounding coral reef is home to many kinds of corals, clams, fish, stingrays and other reef life. Green and hawksbill turtles are seen offshore. The island and reef are part of the traditional sea country of the Gungandji Aboriginal people. They know the island as “Wunyami”. The Gungandji people maintain a close connection with the island, formerly an initiation ground for young men. Green Island has been a popular tourist resort for more than a century. The island became a national park in 1937, a marine park in 1974 and part of the Great Barrier Reef World Heritage Area in 1981. Today the island, reef and beaches are managed together as a recreation area.
