Yes in general keep doing what we are doing but remain vigilant and cautious, I do fear for excessive death, serious illness and impacts to health systems like we are seeing in other places around the world so your observation is spot on. So I will try not to be vague, I don't think Victoria took a relaxed approach and NSW thought they could control the virus but both States went through a lot of suffering and long lockdowns that obviously I would like other States and Territories to avoid. Both NSW and Victoria had fewer options than places that currently have no virus in their communities. I would have thought best to try and avoid what Victoria went through as I don't want their death toll and case numbers. NSW seem to be doing better. WA, SA, Tassie, QLD and the NT so far have had no long lockdown and few deaths so I yes I like that. Getting to a nice high vaccine rate gives me and others a bit more security. My State so far has avoided the worse parts of this pandemic so I have some trepidation going forward.So basically the lesson learned is to keep doing what we're doing, and what the governments of Australia are pushing for: get vaccinated then get a booster.
Your posts come across as: being fearful / conservative about covid (like WA) is right and taking a more relaxed approach (a la NSW and VIC) is dangerous. It's how they come across but I note that you don't come out and say it explicitly. I also see a lot of people conveying that message and notice that they rarely say it explicitly - instead using vague inferences.
But I note that your suggested lesson learned is to do exactly what NSW and VIC have done.
