The federal government conducted a nationwide test of AusAlert, a new national emergency warning system, with loud sirens ringing out across millions of mobile phones. The system uses cell broadcast technology to ping off multiple towers and networks, delivering messages en masse, and achieved nearly 94% tower coverage across the country. AusAlert is scheduled to go live in October ahead of the bushfire season, though not all devices received the test alert.See omnystudio.com/listener for privacy information.
