On the contrary, everybody would be delighted - but seriously surprised.
Australia is opening up it's economy right now, but we did get the new case per day numbers down to single figures - about a factor of fifty down from the peak - before we risked it, and we aren't opening up all the way either.
We do know exactly where the new cases are located, and we do know where most of them got infected. Contact tracing means that the people who might have got infected by the new cases are in their own personal lock down for the next week or so.
