Virtually every phone in the country will blare an emergency siren at 2pm AEST on Monday 27 July, as part of the first Australia-wide test of a new national warning system called AusAlert.

Most phones, and some smartwatches and tablets, will receive a pop-up notification and an alert sound that cannot be silenced – even if your device is on “do not disturb” or silent mode.
