nah, all the rumours you hear are bullshit. you only hear the bad things about us. every country has a certain amount of racist people, and australia is one of them, but 99% everyone is fine. i think you will find we are one of the more friendly countries in the world.
most asian's live in the city, ie melbourne, sydney.
living in the outback eh, you wont find many people out there :P, it will be completly different to where you are from, as if it mostly desert and kangaroos
oh and if you dont like hot weather (40+) you wont survive
i guess theres only one way to find out, and thats to come over and see for yourself.
