I wonder if they should do random supermarket testing for people in the queues. like set-up pop-up station eg. WestGate/Albany Pak'n'Save for couple days. After move to another location. This way they will be testing community and not individuals who already have high possibility to have Covid-19. This would give a better picture if covid-19 has any community transmission. and based on these tests move to level 3/2.
Thats been suggested in the weekend. You would need to test 100,000 to make any use of it. AUS is seeing the same trend. Lockdown has cut COVID-19. It has also cut colds and the flu. Cases we see are still linked to known cases, and are already in lockdown. This is the value of lockdown. Theoretically, if you tested randomly at supermarkets you will find no one as any that are not feeling well wont be shopping. What will happen is if a case or two popped up in your suburb, but no idea how. Then they will heavily test your sunburn, that type of thing.
