Novak Djokovic's father has issued an ominous threat to Australia if they don't let his son into the country to play the Australian Open.
The world number one tennis player was held up at Melbourne's Tullamarine Airport overnight after touching down in the country just before midnight.
He's been questioned by officials about his medical exemption to play in the Grand Slam and asked to supply supporting evidence to prove why he doesn't need to be vaccinated against the coronavirus.
The Age reports there was also an issue in the visa application he submitted because it technically doesn't allow for medical exemptions in regards to the vaccine.
Srđan Đoković has lashed out at Australian officials for detaining and questioning his son and claimed Novak is being held alone in a room without his phone or his entourage.
"I have no idea what's going on, they're holding my son captive for five hours," he explained to local Serbian radio station B92.
"This is a fight for the libertarian world, this is not just a fight for Novak, but a fight for the whole world!
"If they don't let him go in half an hour, we will gather on the street, this is a fight for everyone."
It comes as the Victorian state government revealed it had rejected Novak's application to come into the country.
Acting Sports and Major Events Minister Jaala Pulford said the tennis player no longer had the support of the state government.
"The Federal Government has asked if we will support Novak Djokovic's visa application to enter Australia," she said.
"We will not be providing Novak Djokovic with individual visa application support to participate in the 2022 Australian Open Grand Slam.
"We've always been clear on two points: visa approvals are a matter for the Federal Government, and medical exemptions a matter for doctors."
The Australian government has warned Novak will be put on the first plane out of Australia if he can't prove why he should have been granted a medical exemption.
Prime Minister Scott Morrison said: "We await his presentation and what evidence he provides us 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."
