Useful security information for individuals

The threat of terrorism is serious and ongoing. Members of the public can help to prevent terrorism by being alert to possible suspicious activities.

Whilst we cannot predict every possible terrorist situation, what we do know is that terrorists rely on surprise but also have to undertake a series of processes prior to carrying out an attack.

These processes include, but are not limited to: being radicalised, planning an attack, conducting reconnaissance, purchasing weapons, purchasing other materials they may need, preparing for and then carrying out the attack.

From local and overseas experience, some things to look out for are:

  • persons demonstrating radicalised behaviour
  • unusual videotaping or photography of official buildings or other critical infrastructure
  • suspicious vehicles near significant buildings or in busy public place
  • false or multiple identities
  • unusual purchases of chemicals or other equipment that could be used as weapons
  • unusual odours coming from a place.

For more detail about suspicious behaviour see the National Security website.

If you are aware of something suspicious, trust your instincts and report it to the National Security Hotline on 1800 1234 00. You can provide information in confidence by telephone, e-mail or post to help us address national security threats. The information you provide could be an important piece of the puzzle to prevent a terrorist attack.
