Novak Djokovic is set to be deported from Australia after losing a last-ditch court bid to stay in the country.
Judges rejected the tennis star's appeal after the government cancelled the unvaccinated player's visa on "health and good order" grounds.
The decision has ended his hopes of defending his Australian Open title and winning a record 21st Grand Slam.
Djokovic said he was "extremely disappointed" but respected the ruling, made on the eve of his first match.
"I will co-operate with the relevant authorities in relation to my departure from the country," he said in a statement. It was not immediately clear when he would leave.
