        Off the East Coast, Australia, up to 200 kilometers off shore, a line of surf rises out of the open ocean. Beneath the surface, creating these breaking waves is the most magical marine environment on Earth.

        "I'm Monty Halls, I'm a marine biologist and diver, and I've always been fascinated by the sea.

        For me, there's always been one place that is the epitome of everything that is wonderful about the marine environment.

        It's a true, global icon. It's a Mecca for anyone who's ever heard the word coral-the Great Barrier Reef."

        Stretching for over 2,000 kilometers up the tropical coast of Australia, it is quite simply the largest living structure on the planet. It's made up of almost 3,000 different reefs, each one with a different personality. And it's so much more than just coral. But the Great Barrier Reef is most famous for its underwater world. Here, there is more life than almost anywhere else on Earth.
