The first test of Australia's new national warning system, AusAlert, will target a government building in Canberra's south on Wednesday, June 10.
The National Emergency Management Agency's (NEMA) test will take place at the Molonglo Emergency Services Station, on Cotter Road, between John Gorton Drive and Steve Irwin Avenue, at 10.30am.
The test alert is expected to make mobile phones vibrate, emit a loud siren-like sound lasting about 10 seconds, and say "TEST," and that no action was required.
