Fiji is one of the cheaper and easier countries in the tropical South Pacific.
Unlike south east Asia, it is not crowded, and for Australians it will feel familiar, like Queensland.
You might get tired of everyone yelling BULA! ("hello") to you, even when you are obviously rushing to get somewhere or trying to concentrate on something. But that's the only Fijian you'll need to know if you don't want to learn, as there is plenty of English spoken here.
While most islands do not have a huge diversity of terrestrial wildlife, Fiji has a number of interesting endemic birds, some of which are easy to see.
One of the nicest places to explore is Colo-i-Suva (pronounced Tholo-i-suva) National Park .
