Once again, we can see why Australian borders have no chance of opening soon:
Vaccine complacency threatens to undo Australia’s hard work
Personally I think this is pathetic from Brendan Murphy. It seems like he is absolutely intent in keeping Australia's borders closed for as long as physically possible.
The way things are going, it is almost certain that the vaccine roll-out won't be finished in 2021, and international borders likely to continue till very late 2022/some point 2023.
More proof that clearly the government and its advisors don't actually care about opening up anytime soon.
