Ono-i-Lau is a group of islands within abarrier reef system in theFijian archipelago ofLau Islands (ono means "six" in theFijian language). There are four centralvolcanic islands:Onolevu,Doi (or Ndoi) Lovoni and Ndavura, the uppermost parts of the volcanic edifice rising from theLau Ridge slightly more than 1,000 metres (3,300 feet) belowsea level and on which the reef and other islands are built. There are also three clusters ofcoral limestone islets, Yanuya (50 islets) and Mana (46 islets) on the barrier reef and Niuta (7 tiny islets). A sand cay, Udui, is not counted as one of the six “islands”.
The group forms one of the southernmost of theLau Islands; it is located at 20.80° South and 178.75° West, and occupies an area of 7.9 square kilometres (3.1 square miles). It has a maximum elevation of 113 metres (371 feet). It is 90 kilometres (56 mi) south-southwest ofVatoa, the nearest largish island; the only land further south in the Lau Group is in the two small Tuvana islands of coral limestone and sand.
There are four villages in the group – Nukuni and Lovoni adjacent and Matokana on Onolevu, the largest island, and Doi onDoi.
The group was the location of the first recorded communication betweenFijians and Europeans – CaptainWilliam Oliver and men of the Matavy, tender toHMSPandora, in June 1791.[1]
