Ah, Tony, the problem is that, unlike Ireland, Australia didn't have a St Patrick to send all the snakes across the waters - westwards, I'm told, to where they landed from the Staten Island Ferry and adopted blue uniforms. I, personally, am far more familiar with statins than Statens, so my geography might be a little off. However, had Astralia had such a saint, then eastwards would probably have made more sense.
Italy had a similar plague, but managed to export some key players to the same location from whence they, too, went westwards and founded Las Vegas. I wonder if the pink ranches have similar provenance?
All the Scots did was go away in all directions and create metal objects of great size. Oh, and banks.
