If we go back in history with the Senate system, one of the reasons that the current Senate system has developed is that at various times there has been quite a high level of informality in the Senate vote. I'm looking here at some dates. I think we went to what we would recognize as the modern Senate voting system in about 1948, with some changes in 1984, and it was in response to the complexity of the Senate ballot paper. It's still a complex ballot paper with many candidates and each state paper is different, so I can't give you the statistics for this in any meaningful way.
That's why we went to that system. There has been no overarching public debate about bringing both of these systems into line, and it would be very difficult to do. People broadly accept where we are. The level of informality still remains an issue in both houses, as far as I'm concerned. We've just completed, or are in the process of completing, a recount for one seat in the House of Representatives for the election we've just run, and I think the level of informality was close to 7% in that particular election. It was quite high. We try to work to bring it down as low as possible.
There is, then, no great public clamour for those two systems to be the same, but there were changes recently to try to make the Senate system clearer for the public.
