Conway Reef, known since 1976 by its Fijian name Ceva-I-Ra or Theva-i-Ra Reef, (pronounced [ˈðeβaiˈra]), is a coral reef of atoll type 450 km southwest of the Fiji Islands, but part of the Republic of Fiji. It is located at (21°44′18″S174°38′24″E). It is 2.5 km long in an east-west direction. On the middle of the reef is a small sand cay, 1.8 meters high and about 320 metres long and 73 metres wide, with a land area of two hectares. A stranded wreck of a coaster lies 240 metres south of the centre of the cay, and the wreck of a fishing vessel (Sang Sheng No. 168) lies on the northeast end of the reef. The reef is uninhabited apart from a number of birds which appear to have almost no fear of humans.
