Mr SHORTEN (Maribyrnong—Leader of the Opposition) (14:04): The safety of citizens is the first responsibility of government. Cabinet is the highest level of government. Given that leaks from cabinet are a criminal offence punishable by two years in prison under section 70 of the Crimes Act, what action has the Prime Minister taken to address the serious leaks from his cabinet regarding national security? Government members interjecting— The SPEAKER: There will be silence on my right! The Prime Minister will resume his seat until his own frontbench is quiet. The Prime Minister has the call.
