Senator BIRMINGHAM (South Australia—Minister for Finance, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:44): I know that many things exercise the minds of many voters, and we've canvassed some of those during question time today. I think, first and foremost at this time, health and employment considerations exercise the minds of voters. But in relation to political donations, we have a system where they are reported both by the donor under certain requirements and by the recipient under certain requirements. It's an important check and balance, and yesterday was an example of how it works. The PRESIDENT: Senator Lambie, a final supplementary question.
