Conway Reef, known since 1976 by its Fijian name Ceva-I-Ra Reef (pronounced [ˈðeβaiˈra]), is a coral reef of the atoll type. It is at , and it is 2.5 km long in an east–west direction. In the middle of the reef there is a small sand cay, 1.8 meters high, about 320 metres long, and 73 metres wide, with a land area of two hectares. Politically, it is in the Western Division and the Nadroga-Navosa province of the Republic of Fiji. However, geographically, it lies 450 km southwest of the main complex of the Fiji Islands.
None of the other islands of Fiji are farther away from each other than 75 km (unless you count Rotuma Island, which is politically but not geographically part of Fiji).
In 1838, the Royal Navy Captain Drinkwater Bethune of HMS Conway first came across the reef and recorded it; it was first mapped by several years later by a British captain named Denham, commanding HMS Herald.
There were a couple of wrecks on the island in the 19th century: The brig Rapid, under Captain Arthur Devlin, ran aground on the reef at 0200 h on 14 January 1841, going at a speed of 7 knots with all its sails up: The crew member on lookout duty may not have been paying attention. And 14 years later, on the night of 26 January 1855, the ship Logan of New Bedford, under Captain Wells, was wrecked on Conway Reef (which he referred to as “Sandy Island Reef”).
There have been three recent shipwrecks on the reef (1979, 1981 and 2008), the latest one is the Chinese fishing vessel San Sheng No. 168. The wreck of that ship lies on the northeast end of the reef. The stranded wreck of a coastal trading vessel lies 240 metres south of the centre of the cay.
Conway Reef is uninhabited, apart from some birds that appear to have almost no fear of humans. It offers the rare opportunity to experience diving and snorkeling in a virtually untouched underwater environment.
