The dive
The wall has a vibrant coral community with a wide range of colourful corals. Grey reef sharks are almost always behind the boat when it arrives, and greet divers as they get in. Out in deeper water, trevally, mackerel and tuna wait to feed.
A large colony of clownfish lives in anemones on top of a huge, ancient boulder coral. Up on the reef flat, the smaller reef fish come close, and you’ll likely hear parrotfish munching the coral as they feed on algae.
Conditions and tips
- Wind: the Chapel is the place to be when northerly winds blow.
- Visibility: 10 to 30 metres, averaging about 15 metres.
- Snorkellers: you’ll see the grey reef sharks too, as they patrol the edge of the reef flat where it drops down the wall.
How to dive it
You dive Agincourt Reef on a day trip from Port Douglas. Certified divers get up to three guided dives at three different sites, with a full briefing before each one. Sites are chosen on the day to suit the weather and tides, so we can’t promise a particular site.

What you might see
- Grey reef sharkThe classic reef shark: a stocky grey patroller of walls, drop-offs and current points, often in groups.
- TrevallyBigeye trevally schooling in a slow silver tornado, and giant trevally hunting the reef edge.
- ParrotfishFrom the crunching schools of bumpheads to the sleeping bags of mucus at night, parrotfish are the reef’s builders and gardeners.
- AnemonefishThe clownfish of the reef, living in a sea anemone that would sting anything else. Nearly every site has a family.
