Re: Self-reporting is bound to fail
CBA to follow your link. Will accept your point about numbers of people but not your presumption that it's the vast majority.
It really isn't much of an assumption considering the criteria to get a test is that you must be displaying symptoms!
You can apply for a test if you are:
- an essential worker with coronavirus symptoms
- aged 65 or over with coronavirus symptoms
- someone who cannot work from home and has coronavirus symptoms (for example, construction workers or delivery drivers)

But I digress. Relying on self-reporting is just dumb and is precisely why every sensible country has opted for apps that only a issue warning on the basis of a positive COVID test.
