Australian comedy: what's that?

As filmgoers, do you sometimes wonder if the phrase 'Australian comedy' is an oxymoron? Certainly, as I watched in a concentrated burst over a couple of weeks a half-dozen films from the last five years, it did quite often seem to me that the phrase was yoking together two concepts with little common ground. Then, very recently I caught up with the telemovie, Stiff (John Clarke, 2004), and my spirits rose again. But we'll come back to that.
