World tennis number one Novak Djokovic lost his final bid to avoid deportation from Australia on Sunday, ending an 11-day battle over his Covid-19 vaccination status and slamming his dream of a record 21st Grand Slam.

In a few words, the chief justice of Australia's Federal Court, James Allsop, Sunday dispensed with the unvaccinated tennis superstar's attempt to reinstate his canceled visa.

"The orders of the court are that the amended application be dismissed with costs", Allsop said announcing the unanimous decision, on the eve of the first matches at the Australian Open.

"Extremely disappointed"

The 34-year-old defending champion had been scheduled to play in the evening of the first day. If he had retained the title, he would have become the first men's tennis player in history to win 21 Grand Slams.

Instead, the openly anti-Covid vaccine tennis superstar is now set to be kept in detention pending a quick flight out of Australia.

In his first response, Djokovic expressed he was "extremely disappointed" by the top court's decision to uphold the government's cancellation of his visa, but he would comply and leave the country.

"I respect the Court's ruling and I will cooperate with the relevant authorities in relation to my departure from the country," he said in a statement.

Risk to Australia's public order

Three Federal Court judges had listened to a half-day of legal back-and-forth about Djokovic's alleged risk to public order in Australia.

Immigration Minister Alex Hawke said Djokovic's stance may inspire anti-vaccine sentiment, leading some people to face the pandemic without vaccination and inspiring anti-vaxxer activists to gather in protests and rallies.

Djokovic has spent much of the last week in immigration detention, with his visa twice being revoked by the government over his refusal to get a Covid-19 vaccine before arrival -- a requirement for most visitors.

Because of the format of the court, the judges' decision will be extremely difficult to appeal by either side.

Besides immediate deportation, the Serbian star also faces a three-year ban from Australia.

For a few days, Djokovic was free to train before a second visa revocation and a return to a notorious Melbourne immigration detention facility.

Many Australians -- who have suffered prolonged lockdowns and border restrictions -- believe the player gamed the system to dodge vaccine entry requirements.

Australia's Immigration Minister has admitted that Djokovic is at "negligible" risk of infecting Australians, but argued his past "disregard" for Covid-19 regulations may pose a risk to public health and encourage people to ignore pandemic rules.
