Located northeast of Port Douglas, Agincourt Reef is a spectacular series of ribbon reefs on the outer edge of the Great Barrier Reef. Positioned along the continental shelf, these long, narrow reef formations are washed by clear Coral Sea currents, providing excellent visibility most of the time and supporting an abundance of marine life.

Comprising numerous interconnected reef systems, Agincourt Reef offers an exceptional range of dive and snorkel sites.

Visitors can explore Agincourt Reef with local operators, including Quicksilver Cruises, which operates a floating pontoon permanently moored on the reef. From this platform, guests can snorkel, dive, or view the reef from semi-submersibles and underwater observatories.

Home to turtles, giant clams, clownfish, and reef sharks, Agincourt Reef supports remarkable biodiversity across pristine coral gardens. Its clear waters and healthy ecosystems make it one of the most sought-after reef destinations in Australia.
