Named after St. Crispin, the Frenchpatron saint of cobblers and tanners,[2] St. Crispin's Reef is located 35 miles off the Queensland coast in the Coral Sea,[3] in latitude 16° 07' 54.14" S longitude 145° 48' 22.46" E, at a depth of 9 metres.[4] It lies east of Undine Reef and south of Agincourt Reefs, close to Opal Reef.[5][6] Protected by neighbor reefs, St. Crispin's structure consists of many shallow sandy channels that reticulate around coral mounds, rather than a typical reef slope. It has an abundance of soft corals and colourful marine life.[7]
Classified by the Marine Park Authority for "Intensive use",[10] the reef has four moorings.[3] In 1998, divers Tom and Eileen Lonergan were accidentally left here by their dive expedition, and went missing. Their bodies were never found. The tragedy inspired the film Open Water.[11]
