National AusAlert test: Monday, 27 July 2026

Wednesday 22 July 2026

A national test of the new AusAlert warning system is planned for 1.30pm ACST (local time) on Monday, 27 July 2026.

The Australian Government will launch AusAlert, a new national emergency warning system, in October 2026. Before it is launched, the system is being tested to make sure it works as intended.

The national test will send a test Critical Alert, which is expected to be received by all compatible mobile devices. This follows local community-based tests held across Australia throughout June this year.

The Critical Alert may cause a vibration and a siren-like warning sound, even if your device:

• is set to ‘silent’ or ‘do not disturb’
• does not have a working SIM card.

You cannot opt out of receiving Critical Alerts.

If receiving the test Critical Alert may cause stress or harm, and you do not want to receive it, you will need to turn your device off or switch to aeroplane/flight mode before the alert time and remain in aeroplane/flight mode for at least one hour after the alert.

What to do

As this is only a test, no action is required. Do not call Triple Zero (000).

For road users

If you receive the test alert while driving or riding, stay calm and do not touch your device.

Devices connected to in-vehicle audio systems may amplify the sound during the test. If this is of concern to you, please disconnect your device from your vehicle's audio system before the test.

Mobile phone laws still apply – do not touch your device or read the alert while your vehicle is moving.

Only check the AusAlert message when it is safe and legal to do so.

About AusAlert

AusAlert is another way the Australian Government is helping to keep Australians safe.

AusAlert uses the latest cell-broadcast technology to send near-instant emergency messages to compatible mobile devices. This is considered international best practice.

Cell-broadcast technology sends a mass broadcast from a nearby mobile phone tower. It does not send messages one by one to mobile numbers like SMS systems do.

AusAlert could be used during:

• natural hazards such as bushfires, floods and storms
• significant events such as public health emergencies, public safety or biosecurity incidents.
