The Great Barrier Reef was inscribed as a UNESCO World Heritage Site in 1981.
The listing recognized the reef as an exceptional natural site for its immense scale, geological history, ecological processes, and extraordinary marine biodiversity. It was among Australia’s first World Heritage inscriptions, alongside Kakadu National Park and the Willandra Lakes Region.
The reef is not a single wall of coral. It is a vast ecosystem containing thousands of individual reefs, hundreds of islands, lagoons, channels, and cays along Queensland’s northeastern coast. UNESCO’s designation covers the Great Barrier Reef World Heritage Area, which is broader than the most commonly pictured coral formations.
A common mix-up is 2008, the year the Lagoons of New Caledonia were inscribed. The Great Barrier Reef’s 1981 listing also predates later Australian heritage designations, including its national heritage listing in 2007.
