Australian Open: Novak Djokovic's family declares 'greatest victory' after anti-vax visa exemption upheld

Novak Djokovic's family has hailed the "biggest victory" of the world No.1's life, claiming the battle to overturn his visa cancellation would only make him stronger, as he bids for a record 21st Grand Slam at the Australian Open.

Djokovic has returned to training, after being released from Australian immigration detention, where he had been since a dispute over his medical exemption from the COVID-19 vaccination requirements to play.

"I'm pleased and grateful that the judge overturned my visa cancellation," the Serbian tweets, posting a picture of his team on court at Melbourne Park. "Despite all that has happened, I want to stay and try to compete in the Australian Open.

"I remain focused on that. I flew here to play at one of the most important events we have in front of the amazing fans."

Djokovic aims to lift a 21st Grand Slam at the Australian Open, which gets under way on January 17, to nudge ahead of Roger Federer and Rafa Nadal, with whom he is currently tied on 20.

The player's family say his release was the "biggest victory of his life".

"This will only give him the extra strength," says father Srdjan. "They don't know what they have done.

"He will win another 10 Grand Slams. Victory has made him even more eager to get back on to the court."

Brother Djordje Djokovic has told the same news conference at Belgrade:"Novak is free and just a moment ago he went to the tennis court to practice. 

"He's out there to set another record. He is an athlete and the best tennis player in the world of all times.

"Novak has always advocated freedom of choice, nothing more."

Judge Anthony Kelly ruled that the Federal Government's decision to cancel Djokovic's visa last week was "unreasonable" and ordered his release, but the Australian Government could still deport Djokovic.

A spokesman for Immigration Minister Alex Hawke says he is considering using his personal power to again revoke Djokovic's visa.
