But in court documents released on Saturday, Djokovic's lawyers argue the player had been granted a temporary visa by Tennis Australia because of his recent infection.
djokovic was denied entry to australia after landing in melbourne this week to play in the australian open.
The world's top ranked tennis player is currently in an immigration detention centre ahead of a court case on Monday.
His case has caused a huge outcry in Australia and made headlines around the world.
Czech doubles specialist Renata Voracova has left the country voluntarily after having her visa cancelled by the Australian Border Force ( ABF ) on Thursday.
There had been no prior announcement of Djokovic's Covid infection, which was confirmed by a PCR test on 16 December.
According to news agency AFP, also on 17 December, he posed maskless with young players at the Novak tennis centre.
It is unclear whether he knew he had Covid when the photos were taken.
However, Serbian Prime Minister Ana Brnabic said Djokovic would remain at the Park Hotel until a final decision was made.
Serbian Prime Minister Ana Brnabic said : "We managed to agree that he gets gluten-free food delivered, to get exercise equipment, he has been given a laptop, a SIM card so that he can be in contact with his family."
"it's that simple," she said.
djokovic's challenge to the visa cancellation were published by the federal circuit court hearing on monday.
The documents reveal that Djokovic relied on a very recent Covid-19 infection, recorded on 16 December by the Institute of Public Health of Serbia, to argue he was exempt from vaccine travel requirements.
He was granted a temporary visa to enter Australia on 18 November, and received a letter from the chief medical officer of Tennis Australia on 30 December recording he had a "medical exemption from Covid vaccination" on the ground that he had recently recovered from the virus.
He was told by Australian government officials that they would make a decision imminently, but would give him 20 minutes to make any further arguments.
About 5.20am, Djokovic said he asked for more time to rest and to "talk to [ his ] solicitor again".
Serbian officials are "trying everything to make the situation easier for Djokovic", a statement said.
He alleges the delegate for the minister for home affairs, Karen Andrews, failed to give him proper notice of the cancellation of his visa, misapplied recommendations from the Australian Technical Advisory Group on Immunisation ( Atagi ), and failed to take account of "highly probative evidence" that Djokovic had a medical contraindication allowing him to travel.
The scandal surrounding Djokovic deepened on Saturday, following revelations that Tennis Australia informed players that a prior infection would be a reason to exempt them from Australia's tough border restrictions.
That advice was given despite the health department telling Tennis Australia on two occasions that exemptions did not exist for those recently infected with Covid.
Tennis Australia has largely refused to answer questions or media queries about its handling of the matter.
But a leaked video of Tennis Australia boss Craig Tiley emerged in News Corp papers on Saturday afternoon, showing him telling his staff they had done "an unbelievable job" in handling the affair.
"We 've chosen at this point not to be very public with it and simply because there is a pending lawsuit related to entry into Australia.
Once that has run its course, we ’ ll be able to share more with you," he said.
"There's a lot of finger-pointing going on and a lot of blaming going on, but I can assure you our team has done an unbelievable job and have done everything they possibly could according to all the instructions that they have been provided."
Further details also emerged about Tiley's interactions with Atagi about exemptions for players either recently infected with Covid or who had only received one vaccination dose.
The Age reported that Tiley had told Atagi the treatment of such players "goes to the heart of the viability of the Australian Open".
Novak Djokovic has been given access to gluten-free meal deliveries and exercise equipment during his stay in immigration detention, according to the Serbian prime minister's office.
In his pre-tournament press conference, Australian tennis star Nick Kyrgios described the treatment of Djokovic as "not really humane" and criticised the media's reporting.
The tennis player had also asked for alternative accommodation so he could train for the tournament which starts on 17 January.
They say he tested positive for COVID-19 on 16 December and he had a valid visa and medical exemption from the organiser of the Australian Open.
"I don't know.
His request to move to a private residence was rejected.
I reckon he ’ s going to be pissed off.
