Australia cancels visa of world tennis No.1 Novak Djokovic and intends to deport him on Thursday, with his lawyers expected to appeal.

Earlier Australian Prime Minister Scott Morrison said: "Any individual seeking to enter Australia must comply with our border requirements.

"He has to because if he's not vaccinated, he must provide acceptable proof that he cannot be vaccinated for medical reasons and to be able to access the same travel arrangements, as fully vaccinated travellers.

"So we await his presentation and what evidence he provides to support that. If that evidence is insufficient, then he won't be treated any different to anyone else and he'll be on the next plane home.

"There should be no special rules for Novak Djokovic at all, none whatsoever."
