The dive
The bay runs from 22 metres to 12 metres. What’s left of the boat lies here: the engine block, generator, cooling pipes, plating and a large fluted anchor. On the southern side of the bay are imposing pinnacles and colourful coral gardens.
The corals include branching, shrub and plate corals and large boulder corals, with sandy patches in between. Fish are everywhere: sweetlips, fusiliers, clownfish and other anemonefish. Green turtles are often seen, with the occasional grey reef whaler. On most dives you’ll also meet a large white-tip reef shark the crew call Smiley.
Conditions and tips
On an incoming tide you can drift from the outer edge of the reef into the bay. Otherwise it’s a static dive from one of two moorings. Visibility is generally good, 15 to 20 metres on the incoming tide.
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
- Green turtleThe turtle you’ll meet most on the reef: grazing on the shallows, resting under ledges, surfacing to breathe beside the boat.
- Whitetip reef sharkThe slender shark asleep under the ledge. Harmless, curious at night, and a resident at several of our sites.
- Grey reef sharkThe classic reef shark: a stocky grey patroller of walls, drop-offs and current points, often in groups.
- AnemonefishThe clownfish of the reef, living in a sea anemone that would sting anything else. Nearly every site has a family.
- SweetlipsStriped, spotted and thick-lipped, hanging in patient schools under the overhangs by day.
