Nationwide AusAlert mobile phone test – Mon 27 July 2026

AusAlert is a new national emergency warning system starting soon.

On Monday 27 July at 2pm AEST, AusAlert will send a nationwide test alert to compatible mobile devices.

You don’t need to do anything for the test.

Your device will vibrate, play a siren‑like sound for about 10 seconds and display a test message.

To avoid disruption, you can turn your device off or use aeroplane mode before the scheduled test time and leave it off for at least one hour.

You cannot opt out of testing.
