In an Instagram post on Wednesday, the Serbian admitted meeting a journalist for an interview two days after he tested positive on 16 December.

"I accept that I should have rescheduled," he wrote.

His activity has been scrutinised as the Australian government considers whether to deport him.

In the post, he also blamed his agent for making a mistake on the travel form he used to enter Australia. His comments have prompted a new investigation from officials.

Djokovic, who is unvaccinated, is hoping to defend his Australian Open title next week. He had his visa revoked on 6 January shortly after he arrived in the country amid questions over the vaccine exemption that would have permitted him to enter.

On Monday, however, a judge dramatically overturned the decision and ordered the release of the player from detention.

But the government has not ruled out further action - and the possibility remains that the country's immigration minister could cancel his visa for a second time just days before the tournament begins.

"I felt obliged to go ahead and conduct the L'Equipe interview as I didn't want to let the journalist down," Djokovic wrote in the Instagram post. "[I ensured] I socially distanced and wore a mask except when my photograph was being taken."
