Meet the site
The Wreck Site on Agincourt Reef No. 3 combines two things: a sandy lagoon studded with imposing 12 m coral pinnacles, and the shallow remains of a fishing vessel. Silverseries describes the remains as those of a Taiwanese fishing vessel; the Visit Port Douglas Daintree dive guide calls it a roughly 70-year-old sunken fishing boat now heavily overgrown with coral, with swim-throughs, moray eels, cuttlefish, lionfish and barramundi cod. The wreckage is broken and low-lying rather than an intact hull, scattered across the shallows at around 5–8 m. What remains – frames, plates and machinery – has been colonised by hard and soft corals so that it blends into the reef, and it provides hiding places that attract fish in numbers far out of proportion to its size. Moray eels poke from gaps in the plates, lionfish hover under overhangs, and cuttlefish are frequently seen hovering and changing colour nearby. The pinnacles are the other half of the dive. Rising from sand at around 20–24 m, they are covered in corals and surrounded by red bass, spangled emperor, coral trout and groper, with whitetip reef sharks resting on the sand and rays gliding between them. Clownfish occupy anemones on the pinnacle tops. Visibility here can be exceptional, reaching 40 m on the best days, which makes the whole lagoon feel like an aquarium. The standard plan is to visit a pinnacle or two while you are deep, then finish over the wreckage, where the shallow depth gives a long, relaxed end to the dive. Snorkellers can see the wreck from the surface. The history of the vessel is not documented in detail by operators, and it should not be thought of as a wreck dive in the penetration sense – it is a reef dive with an interesting artefact. For newer divers and photographers it is a very enjoyable combination of structure, fish life and clear water.
