Australia will conduct the first nationwide test of its new emergency alert system, AusAlert, on Monday, 27 July, with an emergency “siren” sounding at 2pm AEST for about ten seconds. Reporting from outlets notes that most mobile phones will receive the alert, including devices that are on silent mode or “do not disturb,” with the sound not being fully silenced. Some smartwatches and tablets are also expected to receive notifications and alert sounds. Several states and territories have raised reservations about the approach, but the federal government confirms the test will proceed. Domestic violence advocates and emergency management officials advise people who use hidden “safe phones” for personal safety to consider turning off those devices for up to 24 hours after the test, to avoid unintended alerts reaching abusers. The alerts are expected to be delivered across supported platforms, including newer iPhone and Android models running recent operating system versions, as well as selected Apple Watch models and compatible tablets. The test aims to validate the national system’s reach and alert delivery process.
