It will thus be the first grand slam tournament with such a requirement.
Djokovic - who is chasing his 21st grand slam title, in that case a new record - has still not said whether he has been vaccinated or not.
- We really want Novak here, he knows he has to be vaccinated to play here, says Craig Tiley according to Sky Sports.
Daniel Andrews, Prime Minister of the state of Victoria, has previously commented on a vaccine requirement for players.
