National test – Monday 27 July 2026  

In July, we’ll be testing the AusAlert system nationally.  

A test alert will be sent to every compatible mobile device in Australia at the same time on Monday 27 July 2026. This will happen at about 2:00 pm AEST (1:30 pm ACST/12:00 pm AWST).  

The national test will be a Critical Alert. Your mobile device will vibrate and make a loud siren-like warning sound that lasts about 10 seconds. You can’t opt out of receiving a Critical Alert and it will make this sound even if your device is set to ‘silent’ or ‘do not disturb’.

If receiving the AusAlert national test will disrupt you or cause you or someone you know to feel unsafe, turn your mobile devices off or switch them to ‘aeroplane mode’ before the scheduled test time in your location and leave them off for at least one hour.
