If you're just joining us while we wait for the court hearing to resume, here a reminder of what's been going on in the Novak Djokovic visa saga.

• Australia's government has revoked Djokovic's visa for a second time – this time on "health and good order grounds"
• The row is all about his right to enter the country unvaccinated
• Djokovic, the world's number one men's tennis player, faces deportation and a three-year ban on getting a new visa
• But his lawyers are preparing an appeal and, during an emergency hearing, Australia agreed not to deport him yet
• Djokovic's lawyer argued his visa was cancelled this time not because he was unvaccinated but because it might "excite" the anti-vax movement in Australia - it was the first time we've heard that the government is thinking about that
• Australia's PM Scott Morrison says the decision to revoke the visa was to protect the "sacrifices" made by Australians
• Britain's Andy Murray says "it's not great for tennis" or the Australian Open that this saga is dragging on

The situation is a bit tricky for the Serbian government.

Serbia's Prime Minister Ana Brnabić told the BBC they are doing what they can to support Novak Djokovic. She's been having conversations with her opposite number Scott Morrison and, she says, they've had a positive tone to them.

But ultimately, Serbia acknowledges that this is Australia's business - and it really doesn't want to do anything to harm the countries' relationship by pressing on an issue involving a single person.

Although, as the prime minister said to me, he is Novak Djokovic – the most important individual Serbian living - and they will do everything they can for him.

But in reality, that may not amount to much.

Here's a bit more from government lawyer Stephen Lloyd on what the Australian government wishes to happen in regards to Djokovic's potential detention by immigration authorities.

Lloyd says the government is proposing that Djokovic be detained at 08:00 on Saturday, but would be able to attend his own solicitor's offices after that, escorted by Australian Border Force officers, then back into detention at midday.

He would then be returned to detention for Saturday afternoon and overnight, and then would be brought back to his solicitors' office on Sunday morning for a proposed court hearing, the government says.

The player's lawyer Nick Wood has already told the hearing that he accepts that the government is within its rights to take Djokovic into detention, but warns of a "media circus" should this happen.

The judge has now adjourned the hearing.

Talking about the reasons for the original cancellation of Djokovic's visa, Judge Kelly suggested there are still unresolved questions.

He said that if Djokovic was unvaccinated, it must be the case that he was originally given a medical exemption. The question of why is still unresolved, he said.

However, he noted that the matter is now over as it was part of the considerations of a previous case.

Djokovic should attend our offices at 08:00 tomorrow local time (Saturday morning) and wouldn't be detained before that, government lawyer Stephen Lloyd says.

The lawyer for the Australian government is now addressing the judge.

The Australian government will not undertake removal proceedings, Stephen Lloyd says.

He added that a timetable involving a full hearing on Sunday morning was acceptable to him.

Djokovic's lawyer has attacked the Australian government's decision making process.

Nicholas Wood said his visa was cancelled not because Djokovic was unvaccinated, but because it might excite the anti-vaccination movement in Australia.

He claimed the immigration minister had only considered what effect Djokovic staying in the country would have on anti-vax sentiment, and not what it would do should he be deported. This, he said, was "patently irrational".

Novak Djokovic's lawyer Nick Wood asks the judge to consider holding the full hearing on Sunday, if possible, as the player's legal team are concerned about time.

They suggest that both their legal team and that representing the Australian government get their submissions in on Saturday, and ask the judge to consider hearing the case in full on Sunday.

They would like the decision to be made ahead of Djokovic's planned opening match at the Australian Open on Monday evening.

We are where we are because of the time the immigration minister has taken, Wood says.

We've yet to hear from the lawyers representing the Australian government.

The tennis player's lawyer says that Novak Djokovic is not currently in detention and he does not believe that the Austalian government is planning to take him into detention this evening.

He is said to be still at a residential address.

The legal team representing Novak Djokovic has told the court hearing that they will be seeking an injunction to prevent their client being removed from Australia for now.

Counsel Nick Wood says they intend to submit a formal written application by 22:15 Melbourne time (11:15 GMT).

At the court hearing, Judge Anthony Kelly is talking through the history of the case, and says he wants a quick and efficient winding up of proceedings.

He is explaining the various options for how the case could proceed.

Britain's Andy Murray has been giving his reaction to the latest twist in the Djokovic saga.

"It's unfortunate that it's ended up in this sort of situation, and who knows? I don't know what route he goes down, if he can appeal that and, you know, how long that takes, and can he still be out practising whilst that process is going on or still competing in the tournament?

"Just want it to get resolved. I think it would be good for everyone if that was the case. It just seems like it's dragged on for quite a long time now, and yeah, not great for the tennis, not great for the Australian Open, not great for Novak."

Murray - who has known Djokovic since they were children - was speaking shortly after reaching the final of the Sydney Tennis Classic, in what will be his first ATP final since 2019.

Judge Anthony Kelly has begun an emergency hearing on what will happen next in the Djokovic case.

It is being live streamed, external but you can follow us for updates.

What Melbourne residents think about the latest events? Our colleagues have been finding out.

Australia is currently in the grip of an Omicron wave and seeing over 90,000 cases a day.

After imposing some of the world’s tightest lockdown rules, most states removed restrictions before Christmas, leading to a massive spike in cases.

The state of Victoria is suffering an acute shortage of workers as people are forced into isolation.

There is growing anger at the lack of access to Covid tests. Australia is also holding a general election this year, and the prime minister and other politicians are keenly aware that voters are watching them closely.

Here's more on how Omicron has hit Australia.

Viktor Troicki, current Davis Cup captain for Serbia and one of Novak Djokovic’s closest friends, has questioned why the men's professional tour has not done more for the world number one.

“It’s so confusing and unheard of - the ATP not standing up for their number one player in the world?" he asked following Friday's announcement that the men's world number one had his visa cancelled.

"That was really confusing for me and I didn’t understand it at all. They should let him free."

However, he added his friend was "tough mentally" and trying to stay focused.

"It’s a grand slam and one of the biggest tournaments we have in tennis. This is his only wish, for sure he’ll be disappointed if he isn’t able to play."

An Australian judge is holding an emergency hearing shortly.

A directions hearing will be conducted at 20:45 Melbourne Time (09:45 GMT) before Judge Anthony Kelly of the Federal Circuit Court, the BBC understands.

It refers to a short court appearance where orders are made about what should happen next in a case.

If Djokovic does not play, it will mean a reshuffle of the men's singles draw.

The rules for Grand Slam tournaments state the withdrawal of the top seed before Monday's order of play is released would see the fifth seed - Russia's Andrey Rublev - move into that open position.

That would have a knock-on effect of the 17th seed - France's Gael Monfils - and the next highest-ranked player eligible to be seeded - Kazakhstan's Alexander Bublik - moving into the spots subsequently vacated.

Then, a lucky loser - someone who has lost in the final round of qualifying - comes into the draw.

Tournament organisers are well accustomed to making late changes in draws because of injuries. One because of the world number one being deported from the host country would be unprecedented.

Kristina Keneally, a senior MP for Australia's Labor opposition, appeared to support the decision - but added that he "should never have gotten a visa in the first place".

10 News First journalist Simon Love quotes the Victorian government as saying it would be "inappropriate" for them to comment at this stage.

The Australia Open tournament is due to begin on Monday in Melbourne, the capital of Victoria.
