Fury, shock and widespread confusion unfolded on social media in Australia after tennis great Novak Djokovic announced Tuesday that he was granted a medical exemption to play at the Australian Open, which begins Jan. 17.
However on Thursday, the Australian Border Force confirmed Djokovic's visa has been canceled and he will be denied entry into the country. He could be deported, officials said.
"The Australian Border Force will continue to ensure that those who arrive at our border comply with our laws and entry requirements. The ABF can confirm that Mr. Djokovic failed to provide appropriate evidence to meet the entry requirements to Australia, and his visa has been subsequently cancelled," the Australian Border Force said in a statement. "Non-citizens who do not hold a valid visa on entry or who have had their visa cancelled will be detained and removed from Australia."
Australian Prime Minister Scott Morrison also confirmed Djokovic will not be allowed into the country and said in a Thursday press conference that "rules are rules, and there are no special cases."
Morrison said entry into Australia with a visa requires double vaccination or a medical exemption. “Such an exemption was not in place” for Djokovic when he arrived, according to Morrison, and the tennis player is "subject to the same rules as anyone else.”
“Ultimately, this is the responsibility of the traveler," Morrison said Thursday morning. "It is for the traveler to assert and backup their ability to come into the country consistent with our laws.”
"And if they don’t comply with the rules, then the Australian Border Force will do their job, and they have done their job," added Morrison.
Serbian President Aleksandar Vučić said on his verified Instagram page that he had spoken to Djokovic on the phone, and "the whole of Serbia is with him, and that our authorities are taking all measures to stop the harassment of the best tennis player in the world." It was not clear if he spoke to Djokovic before or after his visa was canceled.
Djokovic's announcement Tuesday was mostly met with heated replies. Other social media platforms, letters to the editor and talk radio in Australia were also flooded with criticism toward Djokovic, who has refused to divulge his COVID vaccination status but said last year he was opposed to it.
“We have been taken for fools," tweeted former Australian football player Kevin Bartlett.
"Many Australians have not been able to return home for two years. There has been little free movement across borders. So regardless of your views on vaccinations, the issue is the consistent rule bending for a selected few ... Grubby decision," said Australian broadcaster Shane Anderson.
"Though we now know that Djokovic plans to play the #AusOpen, there will still be considerable speculation about the legitimacy of his exemption. What 'acute major medical condition,' as listed here by Australian authorities, could a healthy #1-ranked athlete have?" said journalist Ben Rothenberg.
There were some voices of support from his Australian fans -- after all, Aussies are a sporting nation and he is one major away from breaking a tie with Roger Federer and Rafael Nadal, who also have 20 grand slam singles titles. But he would do it in a city that has mixed feelings about the tennis star.
Omicron cases have exploded in Australia in recent weeks since domestic borders were opened, and Victorian residents have suffered some of the strictest COVID controls in the world over the past two years. More than 90% of Australia's over-16 population is fully vaccinated, but some people still cannot travel internationally or interstate because of the measures.
Deputy Victorian Liberal Leader David Southwick called the exemption decision "a disgrace" and a "kick in the guts" to residents.
Prominent Australian emergency physician and former president of the Australian Medical Association Stephen Parnis said the exemption sends the wrong signal to others who have sacrificed to stop COVID.
"I don't care how good a tennis player he is. If he's refusing to get vaccinated, he shouldn't be allowed in … If this exemption is true, it sends an appalling message to millions seeking to reduce COVID-19 risk to themselves and others. Vaccination shows respect, Novak," Parnis said.
Organizers said the defending champion has not been given special status, and insist exemptions are decided by a group of independent doctors on a panel, which makes a blank medical assessment based on whether a candidate has had major surgery, an adverse reaction to a COVID vaccine or if they are in recovery from the virus. Defending the process, Tennis Australia CEO Craig Tiley said, "no one knew who the applicant was."
The Australian government said it's not up to them to decide who gets granted exemptions -- saying it's a matter for the Victorian government, which hosts the tournament each year.
Speaking ahead of Djokovic's arrival in Melbourne, Morrison said Djokovic would not be treated differently from anyone else.
"There should be no special rules for Novak Djokovic at all. None whatsoever," Morrison said.
"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."
