While I agree that the Victorian Government likely has some ability to prevent Novax playing in the Aus Open, legally, I very much doubt that the Victorian Government can prevent him from entering Victoria. The first step is for Novax to enter Australia, clearly a Federal responsibility and, given the constitution specifically stipulates that cross border trade must not be hindered, I doubt that they would have the power. That said, the restrictions on travel between states has been challenged during COVID and was not disallowed so they must have some power.
All in all it is a sh!tshow and I do wonder what pressure was brought to bear any by whom. I suspect the international tennis mob (whoever they are) may have threatened the Aus Open and likely some other pressure on top. Also, I am not convinced Novax has not had the vax, the language used in the announcements is that he has an exemption and can come and play - is it a medical exemption? No idea, maybe the exemption is just exempting him from making public his vaccination status.
Anyway, everyone should go out and get vaccinated, booster yesterday for me and I'm feeling fine (wish I could say the same for my back which is killing me
).
