There's also the case, as was noted by members on this side of the House, the fact of the matter that we have a very tribalist system. I think all of us have seen just how ugly that can get. That adversarial system has produced some of the worst behaviour in this place. But on top of that, it has resulted in some very archaic first-past-the-post thinking, particularly in what the major parties see and characterise as safe seats. I think that's a great example, actually, of the flaws of our present adversarial system.
