The Agincourt Reef system is one of the best known of all the reefs accessible from Port Douglas.  All of HABA's sites are located on Reefs at the very Outer Edge of Australia's Great Barrier Reef Marine Park and each has its' own unique qualities.  On different days in varying conditions HABA has the option of choosing which Reef is best suited to give the optimal protection, visibility and abundance.

Agincourt Reef system consists of four separate reefs commonly called ribbon reefs because of their long narrow structure. This allows a good flow of water to move through and generally keep the water clear.  Clear water means good visibility ensuring the snorkellers and divers can easily see the Reef's inhabitants.  It is all here, Giant Clams, Anemones in every color with a variety of Clownfish, thousands of schooling colorful Reef Fish, the larger Maori Wrasse, several types of Cod, and schools of Pelagics such as Barracuda.

Agincourt Reefs are classified by GBRMPA for "Intensive" use which means unlimited daily passengers.  There are 70 mooring sites, 3 pontoon sites and 3 approved helicopter landing pads.
