Fiji is a cluster of 332 islands and 550 islets in Melanesia, east of Australia, and northeast of New Zealand's North Island. 110 of the islands are permanently inhabited, though nearly 87% of the population of 850,000 people reside on the largest two islands of Viti Levu and Vanua Levu.
Britain made Fiji a subject colony in 1874 and went about establishing sugar plantations. Surprisingly, the first governor of Fiji made a policy that disallowed the use of native laborers or interference with the local culture. As a result, Indian contract laborers were brought in to work the plantations instead.

With such a turbulent history since its 1970 independence it is not surprising that the document granting it independence has been misplaced or lost entirely. However, regardless of the lack of any documents, which are largely symbolic, Fiji will remain a independent nation and would not have to revert back to a colony under the UK.
