In a fresh twist to the already long-winding Novak Djokovic saga, the world No.1 blamed “human error” on Wednesday for a mistake in his Australian immigration paperwork and apologised for breaking isolation protocol for a photoshoot when he had Covid-19 last month.

The 34-year-old Serbian superstar is chasing a record-breaking 21st grand slam victory at the Australian Open beginning on Monday, but could still be deported by the government.

Djokovic, unvaccinated, was held alongside asylum-seekers at a hotel used as a detention centre for immigrants in Melbourne for several days before a judge said that was unreasonable and ordered that he should be set free.

Though training now for the Australian Open at Melbourne Park, Djokovic could still have his visa cancelled again if immigration minister Alex Hawke exercises discretionary power.

Djokovic’s cause was not helped by a mistake in his Australian entry declaration where the “no” box was ticked saying he had not travelled elsewhere in the previous two weeks. In fact, he had gone to Spain from Serbia. “This was submitted by my support team on my behalf – as I told immigration officials on my arrival – and my agent sincerely apologises for the administrative mistake,” Djokovic said on Instagram.

“This was a human error and certainly not deliberate. We are living in challenging times in a global pandemic and sometimes these mistakes can occur.”

Giving wrong information on the form carries a maximum penalty of 12 months’ prison plus a fine and potential visa cancellation. There is widespread anger among Australians, who have a 90 per cent vaccination rate among adults, over the saga.

Djokovic was also apologetic about an interview and photoshoot for French newspaper L’Equipe, which took place on December 18 while he was infected with Covid-19 for the second time.

“I didn’t want to let the journalist down, but did ensure I was socially distanced and wore a mask except when my photograph was being taken,” he said. “This was an error of judgment and I accept that I should have rescheduled this commitment.”

Those opposed to inoculation have made Djokovic a hero, but he said on his post that he would not comment more on the controversy out of respect for Australian authorities.

“I just want to have the opportunity to compete against the best players in the world and perform before one of the best crowds in the world,” he said.

Djokovic’s visa was initially cancelled on grounds he was unvaccinated and his medical exemption — based on having Covid-19 last month — was unsatisfactory.

Conflicting statements

He denied media reports that he knew he was infected when he attended a tennis event in Belgrade on December 17 to present awards to children. Social media showed him posing with the children, without wearing a mask.

“I was asymptomatic and felt good, and I had not received the notification of a positive PCR result until after that event,” he said, adding that a rapid antigen test before the event was negative.

However, in an affidavit to an Australian court, Djokovic said he was diagnosed on December 16, the day before.

Fans, including many Serbian Australians, gave him noisy support when he was detained and his family have portrayed him as a champion for individual rights. But he may face hostility from the crowd if and when he walks out on court.

Australians are battling a wave of the Omicron variant and Melbourne has endured one of the world’s strictest lockdowns. There may be resentment in the dressing room too — all but three of the top-ranked 100 men are inoculated.

With sensitivities heightened as governments and medics worldwide insist vaccination is the only way out of the pandemic, Australia’s top-rating TV network unwittingly revealed the passions behind the scenes.

Two Seven West Media anchors were caught in an expletive-laden “hot mic” off-air conversation condemning Djokovic as “sneaky and lying”.
