Wimbledon may yet prove his salvation, with the Government on Thursday confirming it had no plans to scrap the elite sport exemption that would allow Djokovic to defend his crown regardless of his vaccination status.
There was also no sign of the US government following the lead of its Australian counterpart ahead of this year's US Open.
Djokovic's deportation from Australia was on Thursday delayed until at least Monday after he went to court to overturn the decision to throw him out of the country.
The 34-year-old was being held in immigration detention at a Melbourne hotel having been refused entry by the Australian Border Force (ABF) for his defence of his Australian Open title.
Lawyers for the world No 1 secured an interim injunction preventing his deportation ahead of a hearing at 11pm UK time Sunday (10am local time Monday).
Djokovic had flown to Melbourne after gleefully announcing on Tuesday he had been granted a medical exemption from having to be vaccinated against coronavirus to play at the first grand slam of the year.
But triumph turned to disaster for the vaccine sceptic after he was detained for nine hours amid claims he had sought to gain entry to Australia using invalid documents before being told he would be deported.
In what has become a major diplomatic incident, Djokovic took immediate steps to overturn the decision and, at a hearing on Thursday, the Federal Circuit Court ordered it be put on hold.
A failure to win his legal battle could see Djokovic banned from Australia for three years, a punishment that can be imposed on those whose visas are cancelled.
