Visitors to Australia

Nationwide emergency messaging system

AusAlert sends near‑instant emergency messages to compatible mobile devices such as mobiles, tablets and smartwatches. 

If you’re visiting Australia, you may receive an AusAlert while you’re here if there is an emergency or disaster in or around where you are.

AusAlert may be used for a nationwide disaster or a local emergency, including:

• bushfires
• floods
• cyclones
• severe storms or weather events
• public health emergencies
• security threats
• biosecurity incidents.

AusAlert messages will display in English. 

If English is not your first language, information about AusAlert is available in 19 languages.

When you receive an AusAlert, your device may:

• show a message
• vibrate
• make a loud siren-like sound for about 10 seconds.

An AusAlert looks something like this:

Receiving an AusAlert

To receive an AusAlert you:

• don’t need to sign up
• don’t need an Australian SIM card or eSIM
• don’t need to download an app.

You may receive an AusAlert if you’re in or near an area affected by a disaster. 

Mobile devices from outside Australia are not required to meet Australian telecommunication device standards, so may behave differently to Australian mobile devices when receiving alerts. 

If you receive an AusAlert:

• read the message carefully 
• ask someone you trust for help if needed
• take a screenshot if you want to translate it
• follow the instructions in the alert message.

If you don’t receive an AusAlert, don't worry. It may be because:

• your device might have been turned off or in aeroplane mode during the alert period
• your device might not be compatible with AusAlert.

Mobile phones made before 2019 may not receive AusAlert messages. If your device uses a prepaid SIM card, you may still receive an AusAlert, even if you have no data left.

Why you can trust AusAlert

AusAlert is run by the Australian Government and is safe and secure. Only authorised emergency services organisations and the Australian Government can send AusAlerts.

AusAlert:

• will never ask for your personal or financial details 
• will never include clickable links in alert messages 
• does not know or store your personal information 
• does not know or store your phone number 
• does not track your location 
• does not require you to sign up or download an app. 

If you receive anything that seems suspicious, you can report it to ScamWatch. 

Get ready for AusAlert

AusAlert will be tested across Australia in June and July 2026.

You or someone you care for may receive a test alert.

During AusAlert community and national testing:

• a message may appear on your screen
• you may hear a loud siren sound for about 10 seconds
• you do not need to do anything.

Safe testing

If an AusAlert test message may cause stress or harm, you can turn off your device or switch it to aeroplane mode before the test time in your location. Leave your device off for at least one hour.

Important: you will still receive an AusAlert test if your phone is on ‘silent’ or ‘do not disturb’.
