Senator PATERSON (Victoria) (14:00): My question is to the Minister representing the Minister for Home Affairs, Senator Watt. An audit, through questions on notice, revealed that almost 1,000 units of surveillance equipment provided by Chinese-government-linked companies Hikvision and Dahua are installed across more than 250 Commonwealth sites. I welcome defence minister Richard Marles's comments today that they'll be removed from his department. Minister, is the government concerned about this national security risk at other departments and agencies?
