Melbourne started their lockdown in winter. Everyone obeyed it. It was strongly enforced [1, 2]. They beat coronavirus. And now they can enjoy their summer.
I live in London. At one point in the summer, our covid rates were lower than Melbourne's. But the UK's messaging was confused and contradictory ("eat out to help out", test and trace was shambolic, rules were not enforced). So no one is the least surprised that it has got out of control again so quickly.
[1] My parents live half an hour's drive from Melbourne. Police stopped every car on the highways to enforce no travel, fined the drivers and made them turn back home.
[2] One party of 26 people got busted ordering KFC to the same address and fined $26,000.
>The Avalon cluster has grown to 38, with 21 out of yesterday's 23 cases linked to it and another two still under investigation.
It isn't fair and might not even be entirely honest to describe this to a (mostly US) audience with a phrase like "numbers seem to be up again".
The trigger for Australia to go back into lockdown would be considered a giant fat ignorable nothingburger in almost every part of the US.
Short lockdown maybe, back to normal soon, not too many other places will be able to brag about that.
We will be able to save all the lives prior to vaccination that nations with less willpower seem willing to spend.
