Bula! You're looking for a large RX bottle. In addition to a log and snowman pencil, the original contents include 3 coins (French, Fiji, USA), a Peace Dove, and "Relaxing" trackable geo-coin.
Do you have some change to spare? From what country?
Blue Lagoon is a great place to explore. Dive or snorkel in the lagoon where you can see giant clams and sea cucumbers.
Go for a walk around Nanuya Lailai (low tide only...), or hike up to a platform built at the highest point on the island. There's a Fijian village with farm crops, and chickens and pigs in pens.
The cache is in a relatively busy place (for an island in the South Pacific) so beware of mugglers.
Small note on cache maintenance: There is a local cache guardian who will assist.
