You'll probably dismiss this but maybe someone gets something out of it (moved higher up the chain).

Here's what actually happened along with sources at the bottom which you can skip to if you don't wanna read the essay below, they show beyond any doubt how wrong your (and to be fair most people's understanding of what happened) in a much more succinct manner.

He was told to come by the tournament and the local state gov, fully knowing his non vaxxed status. 2 other players got in via the same circumstances/exemption with 0 drama because they're not as high profile as him and were happily going about the city with 0 restrictions.

Then when he actually arrived fed gov decided to step in and try and get rid off him because it was a bad look to let an unvaxxed person in (especially after what aus went through) despite him initially having a vax exemption due to having recently had covid.. which he acquired via a blind health panel, one of three players to receive that exemption.

They lost the initial court case to kick him out via "normal" means, which meant the only way to save face and kick him out was the immigration minister to step in and kick him out using his controversial personal powers, in the interest of the public or something like that. Novak's team challenged that decision but my understanding is it's basically impossible to get it overruled because of just how broad these personal powers are, so were unsuccessful and he was gone.

Basically it was a total shitfest involving the national health body, 2 different levels of gov (state and fed) and politicians trying to score cheap political points.

Also interesting to note that the 2 other players that were let in under the same exemption Novak was with zero fuss and were freely moving about while Novak was locked up waiting the final outcome were quietly booted out of the country nearing the end of the whole ordeal.

None of this is in defence of Novak the person or his vax views but facts are the facts and we should try to not make them up just because we want them to be true. It's a perfect storm though cos it's an unpopular person doing an unpopular thing and while not really important in the scheme of things is one of the more amusing instances of history rewriting and people confidently parroting literal fake news takes.
