For Australia, you are wrong about that. Australia uses
right-hand drive, like Singapore. Most Commonwealth countries
(countries that had political links with the U.K. at some time or
the other) use right-hand drive, such as the U.K. itself,
Singapore, Hong Kong (it was a colony of Britain, which is why it
differed from the rest of China), New Zealand, etc. Few exceptions
exists, such as Japan (right-hand drive) or Canada (left-hand
drive).
