Season 1  |  Episode 2  |  ABC  |  April 17, 2016

In this second episode, David Attenborough continues his exploration of the Great Barrier Reef aboard the research vessel The Alucia. This time he discovers the incredible animals that visit the Reef every year, some travelling thousands of miles to get there.

David travels out to one of the most inaccessible corners of the Coral Sea, the stunning Osprey Reef - a mountain in the ocean just off the edge of the Great Barrier. Here he dives into shark infested waters in the Triton submersible, to take a closer look at the animals that use Osprey to navigate huge distances to particular locations on the Barrier Reef. One of these is the tiny Raine Island, a destination for tiger sharks because of another arriving visitor - the green sea turtle. David witnessed a baby turtle hatching here almost 60 years ago. Now, the tens of thousands of turtles that return to lay eggs every year are under threat, but an incredible plan by scientists may save this island and its turtles from disaster.

David's journey also takes him to the forested Heron Island to witness thousands of nesting birds, the waters of Lady Elliot Island to marvel at the manta rays that come here for a good clean, and to the Ribbon Reefs to meet a mysterious dwarf minke whale who visits each winter and seeks out human contact. When David first visited the Reef, science knew very little about visiting creatures and why they came, but new tracking technology allows him to follow the story of these visitors like never before, revealing their surprising reasons for returning, and why the Reef is vital for their survival.

When David Attenborough first visited the Great Barrier Reef in 1957, it seemed it would last forever, but since then the coral has been disappearing at an unprecedented rate. In this final episode the research vessel undertakes its most important mission yet as it travels along the Reef to help David understand what the next few decades may hold for this remarkable community of animals, and what is being done to try and save it.
Its future now under threat, David learns how the Reef has always been one of
natures great survivors, and how the coral reef, its inhabitants and its visitors have adapted to change in the most extraordinary ways. He discovers scans of the Reef that are revealing new secrets about its ancient history, and how it has lived through great change before. He visits the stunning reef top at Heron Island, meeting its peculiar inhabitants who face daily challenges from the elements, including a shark that can survive out of water; and we join a dive on the incredible shipwreck that hosts a unique community of animals that has endured countless cyclones. But David discovers the impact of humans over the last few decades has had a dramatic impact on the Reefs health.
After consulting the Reefs top scientists and visiting its island research stations, he embarks on an ambitious mission of his own, the deepest dive ever attempted on the Reef, to examine the resilient coral that live down in the depths to see if they hold any answers which may help to overcome the challenges that lie ahead. But despite the discoveries being made by scientists and in the Reefs furthest reaches, David is still concerned about the future of this incredibly complex and beautiful ecosystem so vital for the worlds oceans.
