In Australia we also drive in the correct side of the road (left of course ). But most visitors to Australia don't find the driving as much of a problem as coping with the metric system. And the hardest to come to grips with is our use of metric time.

When using metric time, you have to remember that there are 100 metric seconds in a metric minute, and 100 metric minutes in a metric hour, and 10 metric hours in a half-day.

It really is much simpler than that imperial time system used in the USA. But make sure you get a dual-time-system watch or alarm clock before travelling, otherwise you will find yourself waking up at the wrong time .

PS. most people just blame it on jet-lag (both the driving and the time calculations).

Have a great trip ... and watch out for the round-abouts.

The best road sign I have seen was in the UK (Yorkshire moors actually) that read "Gan Canny for 1/3 mile".
