About Us

National security

The Australian Government's first priority is to keep our community safe from those who seek to do us harm.

The Commonwealth works closely with its state and territory counterparts to ensure our police and security agencies have the powers they need to fight terrorism. Terrorism is a global challenge, and we work closely with our international partners in the region and beyond.

Australia faces national security challenges that continue to evolve, so we keep our legislation and capabilities under constant review to meet these emerging needs. The establishment of the Home Affairs portfolio builds the foundations of a more integrated approach to our nation's security.

The Australian National Security website provides more information and resources relating to Australia's response to terrorism, including terrorist organisations listed under the Criminal Code.
