It's important to interpret the numbers. There's a rapidly growing outbreak in Albury-Wodonga but 60% of cases are under 16 years old. Almost all of these will have a mild illness and won't trigger conditions that require lockdown. I agree that the proposed law is overreach, but it's unlikely to pass the upper house. I think that the decision should remain with the CHO, but that Parliament should be required to sit throughout any state of emergency so that there can be a public political accountability. That risks it turning into the usual political shit fight, but its better than Government by executive rule.
Once we reach 90% of over 16s double vaccinated, the virus will struggle to transmit in any group other than school aged kids. Teachers should be a priority for early third doses but luckily the summer break is arriving and 5-12 year olds should be approved for vaccination by Xmas or soon after, so next year will look quite different
