The world's southernmost coral reef, 600 km offshore, mixing tropical, subtropical and temperate marine life.
Lord Howe Island deserves its own destination hub rather than being hidden inside a generic New South Wales directory. Administratively it is part of NSW; practically, it is an isolated oceanic island 600 kilometres off the east coast with an ecology that exists nowhere else.
Official Lord Howe Island information describes more than 90 coral species and approximately 500 fish species. The reef is among the world's southernmost coral reef systems, which is precisely what makes it unusual — tropical corals growing at a latitude that should be too cold for them.
