Those who don't want to fight the virus have weaponised contact tracing as the silver bullet that can keep everything open. It won't work, it hasn't worked anywhere, exponential growth quickly swamps the tracers. Sydney's outbreak may be working right now, but because it's a wealthy, geographically isolated community where residents can easily work from home, if they work at all. Melbourne's outbreak was in dense, poor areas of the city where everybody had to work and travel, just to be able to eat. Context is everything.
