CHRIS PENK: Well, my colleague and friend Simon Watts, who's led the charge for us admirably on this side of the House, points out that could actually be the case, I suppose, actually—and this is the point at which I realise I shouldn't be too light about the subject—for those who have a home address that might change due to the vagaries of the situation of movement—physical movement in the case of earthquakes; floods, fires, and famines, etc., and other "f" words that come to mind. You've got to be careful, of course, with "f" words that come to mind during a parliamentary debate, but I think I'm on safe ground with this one, so to speak.
