There are a few things that I've noticed since arriving here that really make me think - you gotta love the Aussies:
1. If the traffic lights turn to amber as you approach it's not telling you slow down and stop it's actually a signal to speed up way past the limit and dash over that junction.
2. If the road has an uneven surface rather than even it out it they'll just put a large sign up to let you know you're going to bump along for a while
3. Durex adverts on the radio at breakfast time - good job the children don't pay too much attention to the background noise...
and probably a hundred more but those are the three I've been pondering for a while
