I don't see that the states have any choice. Outside of a total lockdown, it's either sectional lockdown and containment, which probably doesn't work anyway (NSW will be the decider) or let it rip. The economic impact is the same either way, particularly around small business, either you can't do the job yourself or supply issues from those businesses you depend upon, same result. View it like rolling strike action from the 70"s. If and when NSW falls, there are two options, shutdown like VIC or let it rip. If you choose the let it rip option then you must accept, your own health system will most likely become overwhelmed and you probably will lose at least one of your own loved ones. Are you willing to make that choice and which will it be.
