     It's only 4 hours flying time from Sydney, but a world away. What better place to rest than a country

where the only place people hurry is on the football field and things are done in "Fiji time"?

     Viti Lev-Great Fiji-is the largest island. Here you'll find the capital Suva and the international airport at

Nadi Vatoa, on the other hand, is a tiny island in the farthest part of Hiji. Then there are 331 other islands,

many of them with places to stay.

     With less than a million people living on islands, you'll never feel crowded And with a climate (气候)

that changes only for five degrees between seasons, there's never a bad time to come.

give you more adventures and special experiences than you could find almost any where in the world.

     Whenever you come, wherever you go, you're sure to see some unforgettable events from war dances

to religious (宗教的) songs, from market days to religious days. It's not just staged for tourists; it's still

a part of everyday life in Fiji And any one of us can enjoy Fiji's spirit by being part of the traditional (传统
