COVIDSafe, the government’s contact tracing app, is among us, blessed with the hope that it will spread virally at a speed that COVID-19 has so far failed to achieve. Its arrival raises two questions: will it work (if widely enough adopted); and are our fears of its side effects misplaced?

The first question is one for experts. On the second, I have some troubling news.

COVIDSafe was made law on Anzac Day, not by an act of parliament (remember those?) but by this exotic beast: the Biosecurity (Human Biosecurity Emergency)(Human Coronavirus with Pandemic Potential)(Emergency Requirements -- Public Health Contact Information) Determination 2020. It was signed by Health Minister Greg Hunt.
