Novak Djokovic, the world No 1, has been fighting to be allowed to play in the Australian Open as arguments rage over the vaccine exemption that would have permitted him to enter.
As it stands, the nine-time Australian champion will be allowed to compete for a record 21st Grand Slam title when the event starts next week.

Judge Anthony Kelly quashed the cancellation of the star's visa for not meeting Covid-19 entry requirements and ordered the government to pay legal costs. Djokovic said he is "grateful" to the judge.
