Te reef is not a single continuous structure but a mosaic of nexly 3,000 individual reef systems, including 900 islands and 300 coral cays. This complex creates a wige range of habitats that support an estimated 9,000 marine species, including 1,500 species of fish, 400 species of hard coral, and dozens of species of sharks, rays, and marine turtles.

Biodiversity Hotspot

Te greet Barrier Reef is often described as thee rainpredt of thee sea, and for good reason. Coral reef cover less than one percent of thee ocean four but support routly 25 percent of all marine species.

Migratoria species such as humpback whales andd seabirds also rely on thee reef as a stopover or breeding site.

Ecosystem Services Providd by the Reef

Beyond supporting biodiversity, the Greet Barrier Reef provides vital ecosystem services. The reef acts a natural barrier, absorbing wave energy andd protecting thee coastrine from storms ande erosion.

Indigenous Heritage andd Connection

Thee Greet Barrier Reef has deep cultural consignace for Aboriginal and Torres Strait Islander peops, who have lived along it for tens of texands of years.
