Anybody's is a Scuba IQ site on the Agincourt complex, described as a dive where you navigate along a wall and then return to the boat through coral-lined alleys. The emphasis is on navigation and exploration: the alleys are narrow sand channels between coral ridges that wind back towards the mooring, and finding your way through them is part of the fun. The wall provides the first part of the dive, with overhangs, soft coral growth and schooling fish along its face.

The alleys are more intimate – coral walls on either side, sand underfoot, and reef fish crowding the edges. Look for resting sharks, stingrays and the occasional turtle in the channels, and for small critters in the coral crevices. Scuba IQ does not publish depths, but the wall-and-alley format suggests a dive in the 5–18 m range.

Visibility is typically 15–30 m. Navigation can be tricky for those unfamiliar with the site, so staying with the guide is recommended. Anybody's suits open water divers who enjoy structure and exploration.

Along with its neighbours Nobody's, Your Place and The Rocks, it spreads divers across the Agincourt complex and offers a quieter alternative to the busiest moorings. It is also a good site for honing navigation skills under the guidance of an instructor. Scuba IQ runs small-group trips, so guides can brief the alley route in detail before the dive and adjust it for the group.

Because it is an operator-specific site name, other Port Douglas boats may know the same mooring by a different name or not use it at all. As on all Agincourt dives, the final choice of site depends on the wind and tide on the day, and the skipper may substitute a nearby mooring if conditions are unsuitable.

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.

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.

Follow the wall away from the mooring at 12–15 m, then turn into the coral-lined alleys and navigate back through them at 6–10 m to the boat, doing the safety stop near the mooring.

Scuba IQ / Blue Dive – small-group Agincourt day trips (max ~20 guests) several days a week; the site names are Scuba IQ's own and may not be used by the larger Quicksilver/Poseidon boats.
