If you go to Singa's - Dont forget to visit the Ministry Of Sound nightclub, after coming outta Perth, it's like ur in heaven with god as ur dj...... lol
But yeah, NZ skiing is supposedly tops... South America - Rio, Venezuela, Peru, etc. Know someone that got back from there a while back, and its great place to see - Beautiful but a bit on the risky side - Good if your up for an adventure.
Whats your budget and how long have you anyway?
Go and see Vicas at flight centre Northbridge, he's bloody helpful and pretty good pricewise too.
Just another 2c..
