Compatible mobile devices across Moree Plains are expected to sound during a national test of Australia’s new AusAlert emergency warning system at 2pm AEST on Monday, July 27.
The alert will be clearly identified as a test and no action is required. Residents may notice their device vibrates and plays a loud siren-like warning sound for about 10 seconds, even if it is set to silent or Do Not Disturb.
AusAlert is Australia’s new national emergency warning system, which uses cell broadcast technology to send emergency warnings to compatible mobile devices in affected areas. The system is expected to begin operating nationally in October 2026 following testing.
During the national test, a single Critical AusAlert will be sent to compatible devices across Australia at the same time. In New South Wales, the test is scheduled for 2pm AEST.
An on-screen message will clearly state that it is a test and that no action is required. In a real emergency, AusAlert messages will provide information about the emergency, where it is occurring, how serious it is and any actions people should take.
AusAlert is expected to work on many mobile phones, selected smartwatches and some tablets that meet the required software standards. Devices do not need a working SIM card to receive an alert, although Apple iPads are not expected to receive AusAlerts.
You can hear a sample of the alert sound on the official AusAlert national test page.
People who keep a hidden phone or safety device should be aware the test may make compatible devices vibrate, sound and light up, even if they are set to silent or Do Not Disturb. Official AusAlert guidance says people concerned about receiving the alert should keep safety devices switched off or in aeroplane mode before the test, if safe to do so. The national test alert may remain active for up to an hour.
Not everyone will necessarily receive the alert. Compatibility, software version, network conditions, mobile coverage and whether a device is switched on or connected to the mobile network can all affect whether the test is received. In regional and remote areas, AusAlert says phones may still receive an alert if they show “emergency calls only”, provided they are within range of a mobile tower.
Drivers and riders who receive the alert should stay calm and not touch their phone while moving. Mobile phone laws still apply, and the message should only be checked when it is safe and legal to do so.
Moree Plains residents can find further information, translated resources, accessibility information and a sample of the alert sound on the official AusAlert website.
