Personally I don't think it's about the vaccines - it's about when Australia will be open for business again - and NOT be arbitrarily closing certain areas.
This would mean accepting there will be outbreaks, possibly deaths but minimised as much as possible with contract tracing, maybe isolated suburb closures....whatever.
Along with that an improved fast result testing protocol, 14 days is becoming unacceptable and increasingly unpalatable to many.
Now how the feds "encourage" various states/territories to fall into line for the greater good - that appears to be a major roadblock.
