The Australian Government will be testing a new national warning system (AusAlert) to mobile phones on the 27 July 2026. AusAlert will help keep communities informed and prepared during local and national emergencies. To get ready, a test message will be sent to all compatible mobile devices in Australia at 2:00pm, Monday, 27 July 2026. If your device is on, it might vibrate and play a loud, siren-like sound for ten seconds. A suite of materials has been developed to inform community members which includes Easy Read and Auslan.
