Don't know, it has served us well for the last year. We had very short lockdowns in January and April and another now. We have always had very low levels of covid in WA (today was just case number 1023 since it began over a year ago,and over 90% of those are international arrivals that go straight into quarantine) due to short lockdowns as soon as it gets into the community, and having tight control over our border.
Oh, and we just also happen to have probably the best performing economy in the world at the moment, so that's not really an issue either.
It's not normal or sustainable for you to keep your borders shut and people locked inside the country.
Not when you're a developed nation with a healthcare system that could have rolled out the vaccine brilliantly.
The UK have fully vaccinated 32,583,746 people, as of yesterday. In total, 77,038,257 doses have been administered.
Aus has a population of around 28m.
Had the vaccine roll out over there being even half as successful as the UK - or for that matter, in European nations which have now caught up like Germany, France etc - then you having to accept closed borders and snap lockdowns wouldn't be a thing.
The UK needed to rely on the vaccines because the initial response was dreadful. That is absolutely correct. But now, Aus relying on their initial response when they could have and should been pushing the vaccine roll out is just a bit mad too, isn't it?
