He got his visa canceled because they didn’t like what he said about the vaccine and Covid.

The decision to cancel was made by a government minister, and is purely political. The grounds given are largely irrelevant.
And then video surfaced of him giving an interview while he said he had COVID. He choose to apologize for giving an interview while having COVID.
And then he managed to fail to disclose on his entry application that he had traveled to various other countries before coming to Australia.
This is someone who was looking to flaunt the rules and it didn’t work out for him.
Also because he lied on and fabricated his visa documentation.
> Alex Hawke, announced earlier that he cancelled the visa “on health and good order grounds, [and] on the basis that it was in the public interest to do so”
The lawyer for Djokovic states:
> The delegate said Mr Djokovic may infect other people because he’s unvaccinated. The present set of reasons is starkly different. The minister assumes in Mr Djokovic’s favour every single fact that might have been in issue previously, that he’s complied with the law, that he poses only a negligible risk to others, Mr Djokovic has a medical reason not to be vaccinated, and that Mr Djokovic is of good standing.
> Wood [Djokovic's lawyer] says there is a “clear jurisdictional error” of “irrationality” in that the ground of “exciting anti-vax sentiment” is premised on Djokovic only having that impact if he remains in Australia.
> “He has no rational basis to say” Djokovic staying would cause more anti-vax sentiment, Wood submits.
It is not "because he lied on and fabricated his visa documentation."
