Australia's National Terrorism Threat Level is PROBABLE.

NTTAS title graphic.jpg 

From the 26 November 2015 a new National Terrorism Threat Advisory System informs the public about the likelihood of an act of terrorism occurring in Australia. This replaces the four-level National Terrorism Public Alert System.

The new system includes five National Terrorism Threat Levels:

The five-tier system provides greater flexibility in determining the threat levels and will provide information that is more meaningful to the public if the threat level changes.

The national terrorism threat level for Australia is PROBABLE. Credible intelligence, assessed by security agencies indicates that individuals or groups have developed both the intent and capability to conduct a terrorist attack in Australia. The public should continue to exercise caution and report any suspicious incidents to the National Security Hotline by calling 1800 1234 00. Life threatening situations should be reported to the Police by calling Triple Zero (000).

The Australian Government regularly reviews the security environment and the National Terrorism Threat Level. Any changes to the National Terrorism Threat Level will be announced by the Prime Minister, the Director-General of Security or the Commonwealth Counter-Terrorism Coordinator.

In the event of a terrorist incident, Tasmania Police will provide TasALERT with information and guidance for the public and organisations.  The following is provided as general information.

National Approach

Tasmania is part of a national approach to counter terrorism between Commonwealth, State and Territory law enforcement and security agencies. The Council of Australian Governments endorsed and released Australia’s Counter-Terrorism Strategy in July 2015. The strategy provides information to the Australian community on the terrorist threat we face and what is being done to counter it.

The strategy is available on the Australian National Security website:


Special Response and Counter-Terrorism Unit

In Tasmania, the Special Response and Counter-Terrorism Unit (SRCTU) provide the focal point for Tasmanian Government counter-terrorism activities, and establish the arrangements for prevention, response and recovery in relation to terrorist threats. 

The SRCTU has specific responsibility for:

  • Liaison with businesses, the Commonwealth Government and other State and Territory jurisdictions in relation to counter-terrorism issues
  • Provide research and policy advice on counter-terrorism and security-related issues to Government
  • Identify critical infrastructure and advise owner/operators in relation to risk assessment and risk management plans, including advice concerning places of mass gatherings of people.
  • Develop and manage a counter-terrorism exercise and training regime
  • Establish and maintain the capability to respond quickly and effectively to specific terrorist threats
  • Provide advice in respect to security sensitive hazardous materials (See below)
  • Monitor counter-terrorism intelligence


Hazardous Materials

A National Code of Practice for chemicals of security concern is available at  The Code of Practice provides information to companies and individuals that are involved in the making, processing, importing, handling, storing, transporting and selling of hazardous materials. 

The important thing is to report suspicious activity to the National Security Hotline. 

How the Community Can Help

Reporting suspicious behaviour

If you are aware of suspicious activity ring the 24-hour National Security Hotline:

National Security Hotline: 1800 1234 00

From overseas:+61 1300 1234 01.

If you do not speak English well, call the Translating and Interpreting Service on 13 14 50 and ask them to contact the National Security Service and interpret for you.

For TTY users, the number is 1800 234 889.

You can also email or MMS 0429 771 822.

The NSH guarantees that your information can remain confidential and callers may remain anonymous if they wish.

Members of the community can also report suspicious activity direct to Tasmania Police on 131 444 or to Crime Stoppers Tasmania on 1800 333 000.

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 or dumping of fertiliser, chemicals or explosives or their containers
  • 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

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.
