Agincourt Reef No. 4 - The Point

Agincourt Reef No. 4 - The Point is a reef dive site on the fourth section of Agincourt Reef, approximately 65km east of Port Douglas on the outer Great Barrier Reef, Queensland, Australia.

Overview

Agincourt No. 4 is the northernmost of the regularly dived Agincourt sections, positioned at a point where the reef system’s northern end meets open water on multiple sides. This exposed position — “The Point” — funnels currents and concentrates the associated marine activity that current brings: filter feeders extended in the flow, predators positioned to intercept prey, and a general heightening of reef vitality.

At 18 metres maximum depth, The Point offers slightly deeper diving than the southern Agincourt sections, with a more pronounced reef face that provides additional habitat structure. It is frequently rated the best site among the Agincourt sections by visiting divers.

Marine Life

The point position produces the best pelagic sightings of the Agincourt sites. Schools of barracuda occupy the mid-water above the reef edge, and large trevally — giant trevally and golden trevally — hunt along the reef face. Reef sharks are present throughout, typically grey reef sharks cruising the exposed side. Sea turtles are abundant — the Agincourt Reef system has one of the higher turtle densities of any easily-accessible outer reef section. Maori wrasse are large and confident. The reef face at 14–18 metres has developed impressive gorgonian sea fans and soft coral growth due to the current exposure.

Dive Profile

Descend to The Point’s deeper face at 15–18 metres, where the current and sea fan growth are most pronounced. Follow the reef face northward, then round the point and return via the more sheltered eastern side for a contrasting experience. The sheltered eastern face provides a quieter ascent and safety stop.

Entry and Exit

Day trips from Port Douglas with Quicksilver and other operators. The Point is typically a second or third dive of the day after the main pontoon site. Entry from the tender by giant stride. Exit via tender pickup with SMB.

Tips and Recommendations

• Position yourself at the actual point early in the dive for the best chance of encountering barracuda and trevally schools
• The contrast between the exposed and sheltered faces is notable — explore both on a single dive
• Current here is stronger than other Agincourt sites; if you are new to current diving, stay on the sheltered side

Safety Considerations

The Point is the most current-affected of the Agincourt sites. Monitor your position carefully on the exposed face and be prepared to abort the point approach if current is unexpectedly strong. Communicate current strength to the boat crew before descent so they can position accordingly for pickup.

Photography

The Point’s current-driven marine activity creates outstanding opportunities for pelagic fish schools against the open water blue. Position yourself at the reef edge and let the schools come to you. The gorgonian sea fans on the deeper face are excellent for diver-in-context wide-angle images.
