A bit of background: The project was given to a political party associate/donor. They basically forked the Singapore (from memory) open source app and re-skinned it. They didn't wait for Google/Apple's updates allowing OS-level integration, meaning there were battery issues from Bluetooth drain. In some states, they didn't create the proper legal framework, meaning police (and lots of other organisations) were able to get access to the data. Due to the legal and battery issues, no one trusted it and stopped using it. It found under 50~ contacts in total, and only 2 contacts that were previously unknown from other contact tracing efforts. Also, the federal government at the time were very secretive - refused to publish data on the app or published it late or in useless summary form, didn't provide any details as to success rate, denied/stalled FOI requests. It was basically a shitshow.
