On Monday 27 July 2026, a test alert will be sent to all mobile devices in Australia.
This includes most phones, and some smart watches and tablets.
At the time of the test, a single Critical AusAlert test will be sent to every mobile device in Australia. Everyone with a compatible phone or other device in Australia can expect to receive the alert.
Devices will vibrate and play a siren-like warning sound for about 10 seconds.
An AusAlert message will appear on device screens. It will clearly say it is a test.
Exactly how it appears will depend on your device type and operating system.
The only way to not receive a Critical Alert is to turn your mobile device off or switch it to ‘aeroplane mode’.
If receiving an AusAlert test message will disrupt you or cause you or someone you know to feel unsafe, turn off your mobile devices or switch them to aeroplane mode before the scheduled test time in your location and leave them off for at least one hour.
