Visitors

S1 E2: Sixty years after his first visit to the Great Barrier Reef, naturalist Sir David Attenborough returns, this time aboard a research vessel equipped with the latest technology. He examines some of the million migrating animals that visit this marine paradise every year and how each of the reef’s habitats attracts a very different set of visitors. Follow David from the Osprey Reef, a huge mountain hidden beneath the waves, to Raine Island, the green turtle’s favorite nesting area, to Lady Elliot Island, the beauty salon for manta rays.
