Best for intermediate divers, 0-40m, boat entry, moderate current.
Big Buoy at Agincourt Reef is a boat-only site featuring a reef wall and pinnacles that descend from 5 to 40 metres. The site is known for its moderate currents, which facilitate drift dives along the structure. Divers should maintain solid buoyancy control to manage the flow, as conditions can become challenging on certain tidal cycles. Visibility typically ranges from 10 to 35 metres. Due to the presence of boat traffic, surface awareness is essential. The site is suitable for intermediate divers, with the wall and pinnacles offering varied profiles. Titan Triggerfish may be aggressive during their breeding season, and divers should remain cautious of sharp coral and deep sections.

Time your entry to catch the incoming current and let it carry you along the wall toward the pinnacle, as fighting it on the way back is hard work. Check current conditions locally before committing, as it can push beyond comfortable intermediate territory on certain tidal cycles.
The Agincourt Reefs are located approximately 65-70 km northeast of Port Douglas and are accessible only by boat. Several tour operators in Port Douglas and Cairns offer day trips and liveaboards to these reefs.
