Senator WATT (Queensland—Minister for the Environment and Water) (14:56): I will come to the question directly in a moment, but, again, it is correct that our security and intelligence agencies have been working and continue to work to ensure they are prepared for any Australian from this cohort returning home. Senator Duniam's question seeks information about the activities of our security agencies, and, of course, no Australian government would provide the kind of information that Senator Duniam is seeking as to the activities of our security agencies. Those sorts of activities are kept confidential for a reason; it's because they do go to national security matters, so we don't propose to elaborate on what those activities are other than to say that our security intelligence agencies have been working and continue to work to ensure they are prepared for any Australian from this cohort returning home.
