Australia has a conservative government that has brains. They have done the best at isolating Covid and had the least lockdowns and economic damage.
However as Delta goes around the world, approaches that were successful before will not be in the future- without vaccine.
Once anyone who wants the vaccine is vaccinated, the plan is to return to normal.
The UK recorded 35,000 cases yesterday, but the plan is to lift the remaining lockdown measures in 9 days.
