National Terrorism Threat Advisory System
For information on the current alert level, see National Terrorism Public Alert.
The National Terrorism Threat Level is a scale of five levels that tells the public about the likelihood of an act of terrorism occurring in Australia.
Whenever the Government makes a change to the National Terrorism Threat Level it will explain why there is a change. The National Terrorism Threat Advisory System will inform Australians about the likelihood of an act of terrorism occurring in Australia and enable authorities, businesses and individuals to take appropriate measures for their own safety and security as well as that of their family, friends and associates. The National Terrorism Threat Level also provides an indicator to Government agencies enabling them to respond appropriately with national threat preparedness and response planning. This ensures an appropriate level of precaution and vigilance is maintained to minimise the threat of a terrorist incident.
The Australian Government regularly reviews the security environment and the Threat Level.
The Australian Government has introduced a new National Terrorism Threat Advisory System. The System:
- Comprises a five-tier, colour coded, National Terrorism Threat scale to inform the public about the level of the terrorist threat facing the nation
- Includes public advice on the nature of the threat we face and what it means for us
- Will help inform the public so they can decide what measures they can take to protect themselves, families and friends
- Guides national preparation and planning to protect against the threat of a terrorist incident
- Rebalances the threat levels to reflect the current security environment that the country is facing.
Who will communicate a change in threat level?
A change to the National Terrorism Threat Level will be announced by the Prime Minister, the Minister Assisting the Prime Minister on Counter-Terrorism, the Director‑ General of ASIO, or the Counter-Terrorism Coordinator. Information about the new system and the current level can be found at www.nationalsecurity.gov.au
