Unfortunately, it's not that simple. Even though there's no community transmission in the country, should we have an outbreak - very likely - it will affect one of the major international ports, most probably Brisbane, Sydney, or Melbourne. And this will trigger a short lockdown, or some kind of restrictions, which will almost certainly impact crowds and players. Though vaccinating frontier staff will hopefully have reduced this risk substantially.
So while it seems grossly unfair that players should be placed in a state of quasi-quarantine when the risk is next to zero, the peak of the pandemic has passed, and the greater population is free to mingle, if they don't, they place their entire competition at the mercy of this wildcard.
In my opinion, the players should be given priority vaccinations, preferably with Pfizer (because the immunity kicks in sooner), and submit lateral flow tests once or twice a week, rather than the useless temp checks. And then be free of the bubble with acceptance of the low implied risk. At some point we need to start accepting some risk. Next year, COVID will be the flu, and Australia will be playing catchup with those refusing vaccination playing guinea pig.
There's another factor that's going to affect the season that no one is talking about: every player at some point will be immunized and a good percentage will go down with side effects (these are normal) for a day or two, maybe three. They'll have to do these early in the week so they don't affect their ability to play, but it will almost certainly take them out of training.
About half the people I know who've been vaxxed have had some kind of reaction (lethargy, low fever, headache, sore arm). It's nothing to worry about, but it's enough to take a day or two off work. Astrazeneca, it's the first jab; Pfizer, it's the second, unless you've had COVID, in which case it's the first. This is definitely going to **** up a lot of teams' preparation. You heard it here first.
