Explore Agincourt Reef, at the very outer edge of the Barrier Reef. Here, special reefs known as ‘ribbons’ run parallel to the Continental Shelf. Adjacent to the Coral Sea trench, these ribbon reefs are recognised as the most pristine eco-systems in the reef’s environment. Clear water provides the best possible underwater visibility, encourages rich coral growth and supports spectacular marine life. Choose to dive, snorkel, or stay dry and explore the stunning reef from the comfort of a Quicksilver semi-sub, just one meter underwater. Watch the fish feeding from Quicksilver’s unique underwater viewing platform and underwater observatory. Morning and Afternoon tea on board is included.
