Reporting Suspicious Activity

Text Size a a a Print Print this page

The effective protection of the community from terrorism requires a partnership between government, industry and the public.  Communication channels have been established for the collection of security related information. 

The public, owners/operators and their staff know their surroundings better than anyone and are best placed to notice suspicious activity.  Business should establish an internal reporting system and encourage staff to report all security related incidents.  If something doesn’t seem right, it should be reported.

Who do you report to?

  • Dangerous situation or life threatening emergency:   

    Telephone ‘000’.

  • Currently occurring suspicious activity, threat or criminal act, which is not life threatening (Police may be able to attend and investigate the situation):

    Telephone Police on 131 444 

  • A crime that has already occurred and the matter is not an emergency:

    Telephone Police on 131 444

  • Suspicious activity, which you believe may be terrorist related, may also be reported to the National Security Hotline:

Telephone:  1800 123 400 (24 hours)


Mail:  Attorney-General's Department, National Circuit, BARTON ACT 2600

All reports to the Hotline are taken seriously and information received is passed to relevant police, security and intelligence agencies for assessment and further investigation.

What do you report?

Some activities you might consider suspicious:

  • Unusual surveillance, videotaping or photography of important buildings and infrastructure (eg. energy, water, and transport facilities)
  • Damaged to security features (fencing, gates, etc) at your facility or any of the above infrastructure
  • Vehicles parked for long periods near important buildings, infrastructure or busy public places
  • Vehicles, packages or bags abandoned in public places or near important buildings or infrastructure
  • Purchase or possession of large amounts of fertiliser, chemicals or explosives for no apparent legitimate reason
  • Accommodation (including garages, self storage facilities) being used at odd times of the night or day
  • Unusual collection of information about a specific important building or piece of infrastructure
