Novak Djokovic says he is "extremely disappointed" with a court decision to deport him from Australia and prevent his defence of the Australian Open.
Serb Djokovic, who is unvaccinated against Covid-19, failed to overturn a decision from the government to cancel his visa on public health grounds.
The world number one, 34, says he will "respect" the ruling and "cooperate with the relevant authorities".
"I will now be taking some time to rest and to recuperate," he said.
Djokovic was bidding to have the chance to win a record 21st men's Grand Slam title, moving him clear of Spain's Rafael Nadal and Switzerland's Roger Federer for the first time.
