we don't just have to think about the CAA/JAR rules, we have to operate to FAA rules in the US of A, OZ Rules (STRANGE) in OZ etc... etc...

The 'rules' you were told about regarding sheep were only a joke!!
Seriously though, as a non-pilot (ATC), how different are the Oz rules? Do they require more or less fuel......or is it not that simple?
