I'm a born-and-bred Australian (of british descent what's more, about the only claim I have to anything mediteranian is that once upon a time remnants of the Spanish Amada settled in Scotland causing a distinctly swathy strain of Scotish people that I believe my father inherited some of his complection from. I on the other hand got an Irish complection - dark brown hair, pale skin, blue eyes).
