I blame the NSW government. The outbreaks in VIC, ACT and NZ (and QLD, which thankfully have been stamped out to date) all came from there, and was a result of a single case (resulting from poor practices with international flight crews) and the fateful, atrocious decision not to lockdown and follow the covid zero strategy.
Still, that strategy was incredibly successful and saved so many lives and prevented countless infections, and allowed a greater degree of freedom, strangely enough. It's a shame they won't continue it for a bit longer but they are in a great position to move on to relying on vaccines and lighter precautions. It did its job.
One of the ultimate lessons of covid is that we must work together, be responsible for others and care for each other, and if we don't we're fucked. Depressingly, the outcome of that lesson is that there will always be assholes and idiots that won't do that, deliberately, and will fuck us all over. As always, it only takes one bad actor to ruin everything. Still, you have to try.
Jesus, some of the bad takes in this thread. "Unsustainable" is such a red flag at this point, and shows the poster knows nothing or is posting in bad faith.
