Mr TEHAN (Wannon) (14:04): My question is to the Prime Minister. Would the Prime Minister update the House on the action the government is taking to strengthen Australia's national security? Mr Perrett interjecting— The SPEAKER: Before I call the Prime Minister, I would advise the member for Moreton: if he wishes to remain for at least half of question time, he will desist. Otherwise he can leave smartly. I call the honourable Prime Minister, and we will have some silence for the answer.
