Kadavu Province is one of fourteen provinces of Fiji, and forms part of the Eastern Division, which also includes the provinces of Lau, Lomaiviti and Rotuma. Kadavu also belongs to the Burebasaga Confederacy, a hierarchy of chiefs from southern and western Fiji with Roko Tui Dreketi of Rewa as the paramount chief.
The province is divided into nine tikina (districts), each with its own paramount chief and chiefly villages. The tikinas are Tavuki (Tavuki), Naceva (Soso), Nabukelevu (Daviqele), Nakasaleka (Lomanikoro), Sanima (Drue), Yale (Rakiraki), Yawe (Nalotu), Ono (Vabea) and Ravitaki (Ravitaki). Each high chief is a member of the Kadavu Provincial Council. There are 75 villages in the province of Kadavu.
The Kadavu dialects are almost as numerous as the tikinas but with tiny variations between dialects. The Kadavu dialects are closer to the Rewa dialect in Ono and then closer to the Beqa, Serua and Vatulele dialect in the main island with more similarities with the Nadroga and Ba dialects as one moves towards the south of the island. This could all indicate the origin of the inhabitants to an extent.
Kadavu is also the home of the second-largest living organism on Earth, the Great Astrolabe Reef, which lies along the southern side of the island and stretches from the northern part of the island, Ono island, to the southern tip of Kadavu Island, Muanasika Point near Nasau village. The edges of this reef are indicated by two lighthouses: the Solo Light House near Ono Island, and the Washington Lighthouse close to Nagigia Island.
There is no town on the island but Vunisea is where all the government headquarters are, with one high school (boarding school), a primary school, police station, hospital, airstrip and at least five supermarkets. However, there are also two main other stations apart from Vunisea: Kavala and Daviqele.
