Australia’s new national warning system AusAlert uses cell-broadcast technology to send emergency messages to compatible mobile devices. Before it launches in October 2026, we need to test the system to make sure it works as intended. 📱 On Monday 27 July at around 2:00 pm AEST, a test AusAlert will be sent to all compatible mobile devices in the country at the same time. This is called the AusAlert national test. It will be a Critical Alert, which means mobile devices will vibrate, make a loud siren-like warning sound that lasts about 10 seconds, and show an AusAlert test message. ⚠️ Critical Alerts override ‘silent’ or ‘do not disturb’ functions. If the AusAlert national test will disrupt you or cause you or someone you know to feel unsafe, turn mobile devices off or switch them to ‘aeroplane mode’ before the scheduled test time and leave them off for at least one hour.
