I would definately echo Snifters idea of getting hold of a copy of the road rules, as there are several differences between here and the UK, which are worth knowing. When I first moved here in 1994 I had to take the driving test to get my SA licence, which did at least make sure that I knew the road rules. As for the d***h**d who had a go at you, well they exist the world over and it's nothing to do with nationality. It's not a pleasant experience though, hopefully it will be your first and last in Australia.
