Australians Never Get Lost

There's a know-it-all at the eatery table next to me explaining about the directionally-nuanced language of Australians, and how they don't refer to their left leg, but rather their southeast leg, and how they organize things east to west, and nuance language according to direction. I don't think he means aborigines either. Is he talking about Homo Australius G'Day-us? Sounds like he needs to be blindfolded, given a Foster's, spun around, and left out somewhere in the Darling Downs.
