Great Barrier Reef

Australia's underwater wonder

The Great Barrier Reef is the world's largest coral reef system, stretching along the northeast coast of Australia.

It comprises thousands of individual reefs and hundreds of islands, visible from space and home to extraordinary marine biodiversity.

The reef serves as shorthand for vulnerable natural wonders threatened by climate change: Rising ocean temperatures are bleaching the Great Barrier Reef.
