AusAlert is a new national warning system that uses the latest technology to send emergency messages to compatible mobile devices.
It will be ready to use in October 2026, but before it launches, the system is being tested across Australia.
At 11.00am on Saturday, 20 June, compatible mobile devices in Port Lincoln may receive a test alert.
The alert will vibrate and play a loud, siren-like sound that lasts about 10 seconds. If this may disrupt you or cause concern for you or someone you care for, you can turn off your device or switch it to aeroplane mode before the test time and leave it off for at least one hour.
This is only a test – no action is required. In a real emergency, follow the alert instructions to keep yourself and others safe.
