Tennis star Novak Djokovic has had his visa to enter Australia dramatically revoked on his arrival in Melbourne.
The world number one was held in the city’s airport for several hours before border officials announced he had not met entry rules and would be deported.
Djokovic was then taken to a government detention hotel. His lawyers have launched an urgent appeal in court.
It follows a massive backlash over a vaccine exemption Djokovic said he got to play in the Australian Open.
The Serbian player has not spoken about his vaccination status, but last year he said he was “opposed to vaccination”.
Mr Morrison said the ABF had previously advised Tennis Australia on visa expectations.
Though Djokovic’s reason for an exemption has not been disclosed, Mr Morrison said contracting Covid in the past six months was not among federal criteria for one.
The Australian Broadcasting Corporation has reported that two other people were now having their medical exemptions reviewed.
The Federal Circuit Court has adjourned Djokovic’s legal challenge until 18:00 local time (07:00 GMT), after two brief administrative hearings.
Djokovic is now being held at a hotel in the Melbourne suburb of Carlton which is used for immigration detention. The facility has been the site of Covid-19 outbreaks and a recent fire.
Outside the hotel, supporters of Djokovic told the BBC they were angry at his treatment.
“It’s an international scandal and the world is watching,” one woman, identified only as Jelena, echoed outrage in her native Serbian.
Djokovic’s father, Srdjan Djokovic, said his son had been held in a room guarded by police at the airport. “This is not just a fight for Novak, but a fight for the whole world,” he said in a statement released to the media.
President Aleksandar Vucic said the star was a victim of “harassment” and said that “the whole of Serbia” supported him.
Mr Morrison denied the visa cancellation was because of “any particular position in relation to Serbia”, describing the nation as “a good friend of Australia”.
Australia is seeing tens of thousands of Covid-19 cases for the first time after enduring some of the world’s strictest restrictions. More than 90% of Australia’s over-16 population is fully vaccinated, but some people still cannot travel interstate or globally because of current measures.
Many Australians had previously accused the government of allowing the rich and famous to do as they please while ordinary people remained separated from sick and dying loved ones.
News of Djokovic’s exemption triggered an overwhelmingly angry response in Australia.
Former Australian Open tournament director Paul McNamee told local media the visa U-turn was unprecedented, saying it “smells” of politics.
The Australian Open begins on 17 January in Melbourne. Djokovic has previously won the tournament nine times.
