Great Barrier Reef (2012)

Monty Halls explores Australia's Great Barrier Reef, one of the natural wonders of the world and the largest living structure on our planet. Monty explores its full 2000-kilometre length, from the wild outer reefs of the Coral Sea to the tangled mangrove and steaming rainforest on the shoreline; from large mountainous islands to tiny coral cays barely above sea level; from the dark depths of the abyss beyond the reef to colourful coral gardens of the shallows.
