Novak Djokovic has admitted breaching isolation rules after testing positive for Covid-19 last month, describing it as an "error of judgement".
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.
