AusAlert is for everyone in Australia

It sends information about local and national disasters, including what is happening now or what might happen soon.

During a disaster, you may receive an alert if you have a compatible mobile phone, tablet or smart watch.

Who can send an AusAlert?

State and territory emergency services can use AusAlert to send fast, clear messages to the public about local and regional emergencies.

The Australian Government can use AusAlert to send messages to the public about national emergencies.

How AusAlert works

AusAlert uses cell-broadcast technology through active 4G and 5G mobile networks. AusAlert messages should only be received by people near the area affected by the emergency.

Testing and launch

AusAlert will be ready to use in October 2026, but before it launches, the system needs to be tested in local communities across Australia and nationally.
