Australia's coronavirus tracing app, dubbed COVIDSafe, has been released as the nation seeks to contain the spread of the deadly pandemic.
Smartphone users can download the app for iPhones and Android and will be able to register their information on Sunday from 6:00pm AEST.
People who download the app will be asked to supply a name, which can be a pseudonym, their age range, a mobile number and post code.
Those who download the software will be notified if they have contact with another user who tests positive for coronavirus.
Prime Minister Scott Morrison has flagged the app as being essential for Australia to be able to ease coronavirus-induced restrictions across the country.
Using Bluetooth technology, the app "pings" or exchanges a "digital handshake" with another user when they come within 1.5 metres of each other, and then logs this contact and encrypts it.
