Nobody's is one of the Scuba IQ sites on the Agincourt complex, and its name is tongue in cheek: it tends to be a quiet mooring. Scuba IQ describes a site with fish-covered formations, a weaving coral wall and a sandpit, giving it broad appeal to divers of all preferences. The dive combines three habitats.

The coral wall winds along the reef edge, offering overhangs, crevices and soft coral growth where reef fish shelter. The formations – bommies and coral heads – are covered in fish, including schools of fusiliers, chromis and anthias. The sandpit gives a completely different environment, where you might find blue-spotted rays, garden eels, gobies with their partner shrimps and sometimes a resting whitetip shark.

This variety makes Nobody's a good choice for a dive that keeps everyone interested: photographers can find macro subjects in the sand and wide-angle scenes on the wall, while newer divers enjoy the easy navigation along the wall and back. Scuba IQ does not publish depth figures for the site. Based on its description as a wall-and-sand site suitable for all levels, most of the dive will be spent in the 5–18 m band, with the guide setting the maximum depth.

Visibility is typically 15–30 m. Nobody's is a pleasant, relaxed Agincourt dive that highlights the diversity of habitats found on the ribbon reefs, and its quieter nature means you may have it to yourselves – a welcome feeling on a reef system visited by several large day boats.

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 winding coral wall from the mooring at 10–15 m, then cut across to the sandpit to look for rays and garden eels before returning via the fish-covered formations at 6–8 m for the safety stop.

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.
