On Monday 27 July 2026, an AusAlert test message will be sent to all compatible mobile devices in Australia. It will sound and vibrate for around 10 seconds, even if your phone is on silent or Do Not Disturb. If this could disrupt you or cause you or a loved one to feel unsafe, plan ahead by turning your device off, or switch to aeroplane mode, and leave it off for at least 1 hour.
