Reporting suspicious behaviour

The National Security Hotline (NSH) was established in December 2002 to provide reassurance to the community concerning counter-terrorism and to receive information on possible terrorist activity. It is available 24 hours a day, 7 days a week and is operated by trained advisers from a wide range of backgrounds, including police, security and the military. The NSH number is 1800 123 400.

Reports received from the public are immediately passed to the relevant police or security agency for assessment and investigation, if required.

The NSH guarantees that all information remains confidential and callers may remain anonymous if they wish.

When investigating the validity of information received via the NSH, the identity of the information source is never disclosed or divulged and the words 'National Security Hotline' are never used. This ensures the security of the public is not compromised and that they can have full confidence when using the NSH.

Members of the community can also report suspicious activity direct to the police or to BankSA Crime Stoppers on 1800 333 000. Any police officer receiving information relative to suspicious activity will take necessary details and process the matter, as required.

What is a 'suspicious' event or activity?

These activities could include the following (but there may be others):

  • unusual property or vehicle rentals
  • large purchases of fertiliser, chemicals or explosives
  • unusual video taping or photography of official buildings or other critical infrastructure
  • abandoned or suspicious vehicles near public buildings or busy public places
  • anything that appears unusual or out of place.

A guide is that if something worries you, or seems to need further security attention, please report it and let the police or other relevant agency assess the situation.

All reports are taken seriously and investigated and police appreciate and continually rely upon the assistance of the community.

However, it is important that members of the community do not place themselves at risk.

If you see an unattended or suspicious package or bag in a public place, with no apparent reason for being there, it is suggested that you:

  • Ask if anyone owns it
  • If no one does, do not touch it and immediately vacate the area to a safe location
  • Alert others to keep away
  • Record the incident, including a description of the package or bag
  • If in a shopping mall, at a sporting event, in a building or on public transport, contact the relevant security authority
  • And/or call local police or the National Security Hotline on 1800 123 400.

Whilst everyone should be alert to unusual or suspicious activity, the public should not be alarmed and should continue with their daily routines and activities.

You are encouraged to live your life in the normal way but remain alert.
