Port Douglas Agincourt Reef.

If this is your first time to this World Heritage-listed wonder, we recommend you put your family in the hands of the Great Barrier Reef adventure experts, Quicksilver Cruises, for a day on the Great Barrier Reef. Your journey begins in Port Douglas where you will board a wave-piercing catamaran for a 90-minute, 72-kilometre cruise across the tropical holiday paradise to the outer edge of the Australian continental shelf. Your destination is Agincourt Reef, one of the outer reef systems closest to Port Douglas and the furthest reef system that can be reached in a day. Like all good short trips, the journey is part of the adventure. As you wave goodbye to the mainland, the towering mountains and the steep drop into the Coral Sea will unfold before your eyes. You will also pass the magical place where the rainforest meets the Great Barrier Reef, Cape Tribulation, on your way to Agincourt Reef.
