I really hope not, if it were a bush fire it's the same as running around trying to contain spot fires without actually putting any of them out. Fire fighters would know it's only a matter of time before they join up and that's when it gets away from you. Then it becomes a firestorm and that's a serious fire. In my view a pandemic behaves the same way. What are the odds of success.
To be closing down, sending everyone home, deep cleaning, opening up again is just as destructive to the economy and you still have an escalating health issue.
Personally I don't think it's going to end well, but that seems to be the favoured method in NSW, lets see how it goes.
