About Great Barrier Reef
The Great Barrier Reef is the world's largest coral reef system, stretching over 2,300 km along Australia's northeastern Queensland coast. Visible from space, this UNESCO World Heritage Site comprises approximately 3,000 individual reef systems, 900 islands, and supports an extraordinary diversity of marine life. The reef is home to over 1,500 fish species, 400 types of coral, 30 species of whales and dolphins, and six of the world's seven sea turtle species. Snorkeling and diving experiences range from beginner-friendly inner reef sites near Cairns and the Whitsunday Islands to advanced drift dives along the outer reef wall. Seasonal highlights include minke whale encounters between June and July, manta ray aggregations, and coral spawning events in November. The reef also supports important populations of dugongs, giant clams, and reef sharks. Glass-bottom boats and semi-submersible vessels offer alternatives for those who prefer to stay dry. Despite ongoing threats from coral bleaching and climate change, the Great Barrier Reef remains one of the most awe-inspiring natural wonders on Earth and a bucket-list destination for divers worldwide.
