Senator McKENZIE (Victoria—Leader of the Nationals in the Senate) (14:56): Australia already has tough gun laws in place. The question is: Are the existing laws being implemented effectively? How was a person who was assessed by ASIO for close ties with an Islamic State terrorism cell able to access firearms in the state of New South Wales? Honourable senators interjecting— The PRESIDENT: Senator McKenzie, resume your seat. I reminded those on my right, particularly, when questions are being asked, the senator has a right for that question to be heard in silence. That is my expectation. Senator McKenzie, please continue. Senator McKENZIE: I did finish—I finished on 'New South Wales'.
