Australia has imposed stringent border controls and tough lockdowns for the past two years. Perceived special treatment of Djokovic would cause a backlash among a public who have largely been unable to travel and in some cases separated from families. 

There has been confusion over which level of government – state or federal – is responsible for approving vaccine exemptions.

Some see the government’s intervention as politically motivated, with prime minister Scott Morrison struggling in the polls ahead of an election later this year.

Photographs emerged over the weekend showing Djokovic attending a presentation for young tennis players the day after his reported positive PCR test, raising questions over how seriously he took the virus. He attended other events without wearing a mask.

Rallies for refugees 

The player has awaited the hearing holed up in the former Park Hotel, a facility that holds about 32 migrants trapped in Australia’s hardline immigration system – some for years. 

Nobody is allowed in or out except staff.

On Sunday, more than 100 protesters, many of them migrant rights activists, gathered in a park opposite the centre.

“Free, free, the refugees,” the crowd chanted as dozens of police stood by.

Even if Djokovic wins his hearing, the Australian government is likely to appeal, and he may have to remain at the centre while that is pending. 

With a week to go before the January 17 start of the Australian Open, any delay could dash the 34-year-old’s hopes of winning his 10th crown in Melbourne, and a record 21st Grand Slam title.
