One of the biggest failures of COVIDSafe in Australia was that it was so heavily bashed by everyone on it's initial release. Anyone who was anyone binned it as soon as it was released.
With an app like COVIDSafe, where you require to have mass adoption of the app to work (there is no use having 10% of phones operating in the wild with the app installed, you require more like 80-90%, ideally every phone running the app.)
Instead, every techie I spoke to either hated it wasn't open source; or used the fact that the app was based on Singapore's app, but was not subsequently open sourced itself.
I feel that if the powers that be had changed the way that the source was developed, worked with the public a little closer that maybe these issues would not have existed.
But sadly, the damage for COVIDSafe was already done in the first few weeks. There was no resuscitation possible.
I liken it to how the AstraZeneca vaccine was dissed in the media. A small chance of clots was heralded as a major issue, which lead to a extremely slow uptake of a vaccine that is for the most part perfectly fine.
Add to that the fact that privacy was never really enacted for the use of the data gathered by COVIDSafe (and other similar contact tracing tools, for example in Sydney, NSW https://www.smh.com.au/politics/federal/breach-of-trust-poli... ) and you have a perfect storm of an app that no-one really keeps installed.
COVIDSafe was dead on arrival.
