Covidsafe App

The Australian government has launched Covidsafe, an app that traces every person running the app who has been in contact with someone else using the app who has tested positive for coronavirus in the previous few weeks, in a bid to automate coronavirus contact tracing, and allow the easing of restrictions.
How to download COVIDSafe:
Downloading the app is voluntary, and it helps identify people who may have come into contact with someone who has COVID-19.
If they have, they can be advised to take measures to help stop the spread of the disease or get tested.
Users register with the app by entering their mobile phone number so they can be contacted by authorities if needed.
