A guy (named Guy) used to work for me amd he was from Perth. I laughed so many times because he had a thick Aussie accent and daily people would say to him, "Fosta's.. Australian for be-uh."
He would smile and then turn around red-faced.. partially because he was so sick of hearing it and mostly because "Australians hate that piss water."
Tips for novices out there: Australians pronounce "Australia" with the "Au" part silenced.
