At this stage only 70 0r 80 people in Australia have the virus.
You need to listen to a different news source.
Only 70 or 80 people in Australia
have tested positive for the virus, which is not even slightly the same as "only 70 or 80 people in Australia
have the virus. You have no idea how many people have it.
It's 80, of whom 6 are new and 55 are active. 3 are dead. 22 have recovered. But you have folks being tested or being sought for testing because some of your citizens went in for testing and then went about their business before getting the results. And those are just the ones we know of.
Plus your government has secured 64,000,000 masks and intends to be distributing them... and I think that may not do what they are looking for.
