The AusAlert test will send an emergency siren to virtually every phone in Australia on Monday, July 27, 2026, marking the first nationwide trial of a new warning system. This system, designed to alert the public to fires, floods, terrorist incidents, and health emergencies, will broadcast a loud siren and pop-up notification that cannot be silenced, even on do-not-disturb mode.
What Is AusAlert?
AusAlert is Australia’s new national emergency warning system. Unlike current SMS-based alerts, it sends a mass broadcast via mobile phone towers, displaying a notification similar to a phone alert. The system will launch nationally in October 2026 after this test.
How Does the National Test Work?
At 2 pm AEST on Monday, July 27, a test alert will be sent to all mobile devices in Australia, including most phones, smartwatches, and tablets. Users will hear a siren for about 10 seconds and see a pop-up with text like “TEST MESSAGE” and “NO ACTION IS REQUIRED.” Pat Hetherington, interim coordinator general at Nema, says the siren will be “loud enough to get people’s attention” but quieter than a fire alarm.
