Many Australians have reported not receiving a nationwide emergency test alert, known as AusAlert, which was scheduled to be sent to mobile phones on July 27, 2026, at 2 p.m. local time. The ten-second message was intended as a drill to assess the functionality of the emergency warning system.
Complaints emerged on social media shortly after the scheduled alert time, with users expressing frustration over phones remaining silent. Some users reported that while one device received the alert, another in the same household did not. Others questioned whether newer devices, such as the iPhone 15, were compatible, with one user stating, "Is an iPhone 15 seriously too old to receive the AusAlert? Damn, guess I’ll die."
Concerns were also raised about the system's effectiveness even when alerts were received, or when they were not. One user noted receiving the alert despite having turned off AusAlert notifications, while half of their colleagues did not receive it, leading to questions about emergency preparedness. Another user reported their alert arrived ten minutes late.
Beyond missed notifications, some users experienced technical issues coinciding with the test. One complaint indicated that their home internet crashed at precisely 2 p.m. when the alert was sent, and had not yet been restored. Another user, who had turned off their phone during the test, found the internet outage "troubling."
According to the AusAlert website, several factors could explain why some devices did not receive the alert. These include the use of older or incompatible devices, or devices running outdated software versions that do not support the system. Insufficient mobile reception at the time of the test, or issues with the nearest mobile tower, such as maintenance or power outages, were also cited as potential reasons for failure.
Devices were designed to vibrate and emit a sound even when on silent or in Do Not Disturb mode. The widespread reports of missed alerts and associated technical glitches have led to public discussion about the system's reliability and effectiveness in critical situations.
