I suppose that is part of my point.

I am not Aussie.., and admittedly, I don't use the word cunt too often, yet I still believe that there are a variety of contexts in which cunt could use the expression as a kind of endearment - in the aussie fashion, even if neither I nor my audience is aussie. 

Of course, if the tone or context is not right, women would be more sensitive than men to a descriptive usage directed towards them as endearment, unless in the context it is obviously a true descriptive statement that fits behavior, could even be humorous to really make the point.
