Yes, Rich-joy, I think (but couldn't swear to it) that it was the Mavis Bramston Show.

And John Clark did a beaut hour's doco on the origins and development of the Australian Accent on the ABC (Oz, for you USers) last Thursday night; I confess I fall into the camp that maintains there are regional differences in the Oz accent. I always associate "coool" with Victoria and SA and "Kewl" with NSW and Qld. I can't do phonetic symbols but I'm sure you'll understand, even if my attempts mystify nonAussies.
