The Morgue has a spooky name and a gentle personality. It lies north-east of Flying Fish Cove, practically beneath the Sunset Lodge, and was named after a small building on the shoreline that once served as the Settlement's morgue. Extra Divers call it a macro paradise and recommend it for photographers and night divers.

What distinguishes it from many Christmas Island sites is its shallow shelf with giant Acropora and lots of feather stars, and a slope that descends at about 35 degrees rather than a sheer wall. Diveplanit's report notes that the coral formations are unusually large compared with Flying Fish Cove, and that the best diving is around 25 m before a straightforward ascent back to the 5 m shelf for the safety stop.

The fish list is long: emperor angelfish, white-square rockcod (thinspine grouper), ringtail Maori wrasse, raccoon butterflyfish, gilded triggerfish and titan triggerfish, and the relatively rare ribbon eel. Extra Divers add lionfish, cleaner shrimps, Spanish dancers and whitetip reef sharks. For macro enthusiasts the slope and shelf hide nudibranchs, shrimps, crabs and small gobies, and at night Spanish dancers, crustaceans and hunting lionfish and morays appear.

The Morgue suits beginners and photographers, and because it is only a few minutes from the jetty it is the usual choice for boat night dives and for a second dive when time is short. Its moderate slope makes depth easy to control, and the large coral structures make for good wide-angle as well as macro shots. It is also a sensible check-out dive on the first morning of a trip.

Fly from Perth (about 4 hours, two to three flights a week, some via Cocos Islands) and hire a car – there is no public transport. Both dive centres are in The Settlement and launch their boats from the jetty/boat ramp at Flying Fish Cove, normally at about 8 am for a two-dive morning trip. From the cove the boat runs east out of the cove along the Settlement shoreline along the coast for roughly about 5 minutes to the site below Sunset Lodge.

There is no land access to the dive, and the vertical sea cliffs mean no exit other than the boat. Operators choose sites on the morning according to swell and wind.

On the north-east corner of the island, off The Settlement. Sheltered from the south-east trade winds (roughly April/May–November), when it is usually calm, but exposed to northerly and north-westerly monsoon swell from about December to March/April; Extra Divers report February–April as peak swell season when boat diving is often cancelled. The corner catches currents that sweep around the island, so conditions can change within a single dive.

Visibility is normally 25–40 m, lower after heavy rain and during red crab spawning (October–January), which is also when whale sharks are most likely.

Descend onto the shallow Acropora shelf, then follow the 35-degree slope down to about 25 m, where the best of the coral is. Work back up the slope looking for macro subjects and ribbon eels, and do the safety stop on the 5 m shelf.

Extra Divers Christmas Island – regular day and night dive; CI Wet'n'Dry Adventures – regular site. Popular for night dives because it is so close to the jetty.
