Aussies are cool, same as Kiwis.
Haven't met any I didn't like, and I met a few.
Heh, they always want to drive my car though... Actually, they keep forgetting that our steering wheels are on the left hand side of the car, whereas "down-under" they are on the right. So when they go to get in the passenger side of the car, they actually get in the driver side, then we have to switch.
Always get a chuckle out of that.
If they are asking questions alot, its because they are trying to convert english units to metric units. Temperature is a common one.
