About Your Place (Agincourt Reef)
Your Place is another of Scuba IQ's Agincourt sites. The operator describes a dive that ventures towards the reef tip before returning through undulating coral structures, with sharks and turtles among the wildlife. The outward leg towards the tip is where the bigger animals are most likely: reef tips on the Agincourt ribbon reefs catch the tidal flow and attract grey and whitetip reef sharks, schooling fish and turtles.
On the return, the reef becomes a landscape of coral ridges, gullies and mounds – the undulating structures of the description – that make for interesting navigation and hide plenty of reef fish, crustaceans and molluscs. The combination of an open, exploratory leg and a detailed return leg makes the dive feel varied, and the site's quieter status means it is less busy than the flagship moorings. Scuba IQ does not publish depths, but most of the dive will be between 5 and 18 m.
Visibility is typically 15–30 m. The site suits open water divers comfortable with a slightly longer swim, and photographers will find both big-animal and coral-landscape opportunities. Like all Agincourt sites, Your Place is within Great Barrier Reef Marine Park zoning, and the reef supports healthy coral and fish populations.
It is a good option for divers who want a mix of wildlife and reef topography in one dive. Scuba IQ runs its Agincourt trips with small groups, so guides can tailor the route: those wanting to spend more time watching for sharks at the tip can do so, while others explore the coral ridges. Because the site name is used mainly by this operator, ask for it by name if you want to dive it, and bear in mind the final choice always depends on wind and tide on the day.
Getting there & entry
An Agincourt site where divers head towards the reef tip and return through undulating coral structures, with sharks and turtles.
Agincourt day boats leave Crystalbrook Superyacht Marina (formerly the Reef Marina) on Wharf Street, Port Douglas, between about 8:00 and 8:30 am. Park in the marina car park or the free all-day street parking around Wharf and Dixie streets; Quicksilver, Poseidon and Calypso also run coach pick-ups from Port Douglas, Palm Cove and northern Cairns beaches. The run to the Agincourt ribbon reefs on the edge of the continental shelf is about 65–70 km north-east and takes roughly 75–90 minutes on the large catamarans (Silversonic is the fastest), longer on small-group boats such as Scuba IQ/Blue Dive.
You gear up on board and giant-stride from the dive deck at a permanent mooring; the skipper picks the sites on the day to suit wind and tide, so a named site is never guaranteed. Boats are back at the marina around 4:30 pm.
Entry: Giant stride from the dive deck at the mooring, descend the mooring line or free descent
Facilities: Departs Crystalbrook Superyacht Marina, Wharf Street, Port Douglas – car parking, toilets, cafes and restaurants at the marina; dive shops in town for gear hire and air
Weather, swell & tides
Agincourt is an outer ribbon reef on the shelf edge, so it is fully exposed to the south-east trade winds that blow from about April to September. Moorings on the protected western (back-reef) side remain diveable in 15–20 knots, but anything over 25 knots or a 2.5 m+ sea makes the crossing rough and operators may cancel or switch to more sheltered moorings. Calm spells in October–December give the glassiest days and 30 m+ visibility.
The wet season (December–April) brings northerlies, afternoon storms, cyclone risk and occasional reduced visibility after big rain events, although the outer reef is far less affected by run-off than inshore reefs. Marine stingers are present November–May. Tidal currents run along the reef edges and through the gaps between the Agincourt reefs; spring tides strengthen them, so exposed corners are usually dived on the neaps or near slack water.
Best season: June–November for calmer seas and the best visibility outside stinger season (dwarf minke whales June–July, humpbacks July–September); October–December often gives glassy days; wet season (December–April) brings warm water, stingers, cyclone risk and run-off
How the dive is usually run
Swim from the mooring towards the reef tip at 12–15 m, watching the blue for sharks and turtles, then turn and wind back through the undulating coral ridges at 8–10 m to the mooring for the safety stop.

Diving in Port Douglas
Port Douglas boats work the Agincourt ribbon reefs on the very edge of the continental shelf, where the water is clearer and the coral generally healthier than on the Cairns day-boat reefs. Sites like Castle Rock, the Nursery Bommie, Barracuda Bommie and the Wreck Site have swim-throughs, pelagics and reliable 20 m-plus visibility. The Low Isles and Opal Reef are closer, shallower options.
Getting there: An hour north of Cairns airport. Boats depart the Reef Marina at Port Douglas.
