Senator WONG (South Australia—Minister for Foreign Affairs and Leader of the Government in the Senate) (14:00): Thank you for the question. Obviously, those are matters within the Home Affairs portfolio and I'm sure could be was responded to by the Minister for Home Affairs, but what I would say is that this government works to the full extent of the law available to us by the legislation—passed by you—which is obviously limited in parts by the Constitution. Senator Duniam interjecting— Senator WONG: I'll take that interjection because this is the latest issue that the opposition want to run on. After having passed laws which they themselves know have to be constrained because of the constitutional limits, they now want—they are now demanding—as a stunt, that a law be passed which they never sought in government. I think we understand that they are playing politics with national security, and we do not. The PRESIDENT: Senator Duniam, first supplementary?
