A living organism visible from space, where sea turtles glide through cathedrals of coral.
A green sea turtle glides through a cathedral of staghorn coral, its shell dappled by light filtering through warm, clear water. Below, a reef shark rests on a sandy patch between bommies. The Great Barrier Reef does not need its statistics to impress — but they help.
The Great Barrier Reef stretches 2,300 kilometres along the Queensland coast, comprising over 2,900 individual reefs and 900 islands. It is the largest living structure on Earth, visible from space, and home to 1,500 species of fish, 400 types of coral, and six of the world's seven marine turtle species. Access points range from the backpacker hubs of Cairns and Airlie Beach to remote coral cays like Heron Island and Lady Elliot Island, where the reef begins at the shoreline. Snorkelling, introductory scuba, and glass-bottom boats mean the reef is accessible to non-swimmers. The reef's future is uncertain — bleaching events in 2016, 2017, 2020, and 2022 have accelerated scientific and conservation efforts.
