i cant speak for Australia as a whole, but can speak for canberran's. people in canberra are far too relaxed behind the wheel. cause most of our roads are quite wide and open and the fact that canberra has only a population of about 300,000, most people think they can do what they like. more often than not the left hand lane travels quicker than the right hand lane cause someone is sitting at the front of the que doing 60-70 kph in an 80 kph zone. this is quite frustrating....
also, no-one down here knows how to merge. everyone seems to just brake and wait for the other car to merge ahead of them, but not realising that the other car is doing the same!!!
