Apologies if this is a dumb question, but why does it go anticlockwise?
In the Southern Hemisphere the Sun is generally in the northern half of the sky at midday (although not always if north of the Tropic of Capricorn), and the sun appears to move anticlockwise across the sky. If you are facing North sunrise (East) is to your right and sunset (West) is to your left, and the hour hand of the clock pretty much tracks the position of the sun.
