Received this information through one of my email accounts, it describes how the tracing app Aus is using, what it does and can be used for. There are a number of protocols used for virus tracing apps, a couple are pretty safe and don't collect much info and are pretty private to use.
The one they are trying to force upon the Aus people is a tracker and collects large amounts of data from your ph. That's why it drains the battery of so many people, it's constantly collecting and sending your data. If you don't use your ph much then it wouldn't be collecting much, but those who live on their phone's data collection is constant. You can go to the link to read it all, pretty interesting and very logical from a technical aspect. Even with this rapid rise in cases, the app is yet to identify one case anywhere.

"The Pan-European Privacy-Preserving Proximity Tracing (PEPP-PT) and BlueTrace protocols rely on Bluetooth to send and receive temporary ID codes to log encounters between individuals. They also are open source, minimize the amount of data collected, and do not collect geo-location data. However, PEPP-PT and BlueTrace rely on a centralized server to generate the temporary ID codes, which an analysis from the DP-3T developers claims could let the server identify the individual behind any temporary code and trace their movements.
PEPP-PT and BlueTrace also rely on centralized report processing. If you test positive for COVID-19 and you are using one of these apps, you must upload your entire contact log to a central server. The central server then matches your log to the contact details of everyone you encountered and sends out a warning. While this does allow health professionals to verify encounters, which can reduce the number of false positives, this creates a massive database that can be exploited or abused. Moreover, whoever operates this database has access to far more data than is needed to prevent the spread of the virus.
Countries that have adopted or support apps that use PEPP-PT or BlueTrace (or a similar protocol that uses centralized report processing) include:
UK
France
Australia
New Zealand
Singapore"
