Unfortunately I have to listen to them to find out. Our emergency alert system is basically garbage. If there was any kind of sudden emergency like a tornado (this becoming a real threat in Sydney and Perth it’s not common but i hear the phrase “mini-tornado” way too frequently over the last few years) Then our systems are completely inadequate for promptly alerting the population at risk. It’s scraping by for bushfires and other big long lasting dangers, but it’s utterly inadequate for “urgent emergencies”.
