Can you just notify you are playing and then at a later stage confirm you have been
vaccinated? is there a deadline?
Just reading an article which is 6 hours old but could be older on https://www.express.co.uk/sport/tennis/1534172/Novak-Djokovic-Australian-Open-medical-exemption-Covid-vaccine-Scott-Morrison-tennis-news
could receive a medical exemption to play the Australian Open. The world No 1 has been in
doubt to play the season-opening Grand Slam after vaccination became
mandatory for all players, as he refuses to disclose whether he has been jabbed.
Djokovic then put himself on the entry list for the tournament but there was
speculation he would attempt to apply for an exemption to compete without being vaccinated.
As far as I understand, Djokovic just applied to perform at the GS in Australia, but the certificate of vaccination he don't need to give now but when entering Australia, which is logical because we know that Covid certificates have a limited duration.
So, Djokovic is only on the entry list for the GS in Australia, and it is a completely different story whether he will be able to enter Australia without vaccination or not.
Covid's rules in Australia are very strict, probably the strictest in the world and I would be really surprised if the Australian government decides to make an exception for Djokovic.
I think such a decision would infuriate many Australians who have been banned from traveling to Australia or outside Australia for 2 years, even with a Covid certificate or if they have been vaccinated.
It would be a very controversial political decision with very big consequences and I do not believe that any politician in Australia would risk that much, even if it because of Djokovic.
I don't understand why Djokovic is freaking out so much about it. It is not like he would have a disadvantage if literally all other players are vaccinated as well. Look at Joshua Kimmich from Bayern Munich in soccer, rejected to get vaccinated and now his lungs suffer from infiltration and as he is now prone to myocarditis he won't be able to play this year and perhaps even in the beginning of next year.
