Small Talk in Australia

In Australia you never say just a simple Hi! Rather say "Hi, How are you!" and you will be engaged into a cheerful and endless conversation. Its real fun. Yesterday my friend told me that you could play this game with an Aussie anytime. You hardly will win, the last sentence will be theirs! In the morning I also tried it with the taxi driver. And it works. they always answer:) People are very friendly here.
