Senator BRANDIS (Queensland—Attorney-General, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:10): As I said at the conclusion of my answer to your initial question, the threat level remains at 'probable'. What that means is that our authorities advise the government that they assess that a terrorism event on the Australian the mainland is likely. That has been the position since 12 September 2014, when the national terrorism threat level was elevated on the advice of ASIO and the Australian Federal Police. Since that time, Australia has experienced four terror-related attacks, three of them involving fatalities and one involving serious injury. But it is important to know that 11 attacks in an advanced stage of preparation have been disrupted and prevented by our agencies. We have the robust legislative, policy and operational arrangements in place to deal with the current threat environment. The PRESIDENT: Senator Bushby, a final supplementary question?
