Senator BIRMINGHAM (South Australia—Minister for Finance, Minister for Trade, Tourism and Investment, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:03): As Senator Ruston said in her remarks yesterday, there are a number of occasions, including inside of this building, when the Aboriginal flag and the Torres Strait Islander flag are flown. So it is the case that they are flown inside of this building. That was not what yesterday's motion related to; it was specific to inside of this chamber. In relation to our national flags, indeed there are, I think, five recognised national flags across Australia. We do, in terms of the citizenship test, set an importance on understanding a number of different aspects of Australian society, including the recognition of those flags. Honourable senators interjecting— The PRESIDENT: Order! I'll call Senator McCarthy when there is silence. Senator McCarthy, a final supplementary question?
