Green Island

In Australia, things tend to be named literally. Green Island is no exception.

This is a cay (sand island) that happens to have a bit of rain-forest on it. It's the perfect desert island, really. Well, other than the fact that there is a restaurant / swimming pool / etc on it.
And a gift shop.
There's a good beach with lifeguards.
And - oh joy - a big thing. In this case a Big Tuna.
