Australian Warning System

The Australian Warning System (AWS) helps you stay safe and recognise emergency alerts.

It is a national system that provides information and warnings for hazards like:

• bushfires
• extreme heat
• floods
• cyclones
• storms.

The AWS delivers consistent messages so you know what to do when you see an alert.

It’s important that everyone knows and understands the new system.

If you run a business, it is important that you update your workplace cyclone plan accordingly.

AWS icons and warning levels

The AWS has a nationally consistent set of recognisable icons for each hazard and 3 levels of warning:

• yellow - advice: stay up to date
• orange - watch and act: conditions are changing - start taking action
• red - emergency warning: act immediately.

Hazard	Advice	Watch and act	Emergency warning
Cyclone
Fire
Flood
Storm
Extreme heat
Other

For more information about the AWS icons and warning levels, go to the AWS website.

Warning signal

The Standard Emergency Warning Signal is a siren that is used with the AWS at the emergency level when immediate action must be taken.

The siren may be played live or used on:

• radio
• TV
• social media.

Only the NT Emergency Service chief officer, the Bureau of Meteorology NT regional director, or their delegates can authorise the siren.

When you hear the siren, you should pay immediate attention. Listen to the announcement and follow any instructions given.

Voice or message alerts

The text-based Emergency Alert is being replaced with AusAlert in October 2026.

AusAlert will use the latest technology to enable authorities across Australia to send geographically targeted emergency messages to all compatible mobile devices within a 160-metre accuracy.

Ahead of the launch, community-based trials are expected to take place across urban, regional, and remote areas in all states and territories in June 2026. In the Northern Territory, the nominated test location is Tennant Creek.

A national test of AusAlert will take place at 2:00pm AEST on Monday 27 July 2026 following the community testing to validate the system’s full capability and support awareness of the new system.

During the national test, everyone in Australia with a compatible mobile device will receive an alert.

Until AusAlert is operational, the text-based Emergency Alert will continue as the telephone warning tool used by emergency services to:

• send voice messages to land lines
• text messages to mobile phones.

These messages are sent from the phone number +61 444 444 444. If you receive a message from this number, follow all instructions.

Fire danger ratings

The Australian Fire Danger Rating System (AFDRS) is used nationally.

Fire danger ratings describe the potential danger level of a bushfire. They provide the community with information to take action and protect themselves and others from fire hazards.

Fire danger ratings are used to communicate the consequences of a fire, if one was to start. On days when there is minimal risk, ‘no rating’ will be used.

For more information, go to the Australian Fire Danger Rating System website.

Fire ban days

Fire bans are issued by the Bushfires NT Chief Fire Control Officer and NT Fire and Rescue Service Chief Fire Officer for specific areas when weather conditions indicate an increased fire risk.

Fire bans are generally issued for 24-hour periods and are communicated through local media and social media posts.

On fire ban days, no person shall light a fire or cause a fire to be lit in the open within the affected areas.
