Mr DREYFUS (Isaacs—Deputy Manager of Opposition Business) (14:00): My question is to the Prime Minister. I refer to a leaked cabinet document from within the Turnbull government marked 'sensitive' and 'protected'. Given the document refers to details of past and future meetings of the National Security Committee of cabinet, what action has the Prime Minister taken in response to this national security leak, and will the Prime Minister be referring this leak to the Australian Federal Police for investigation?
