Australian Open players remain in quarantine despite reclassified cases

But that did not change the status of any of the flights, meaning all the 72 players remain unable to train outside of their rooms.

Sutton told Australian media: "This does not change broader assessment of the player group in hotel quarantine. As yet, none of the three affected flights have been cleared as a result of the two reclassified cases."

Three new cases associated with the Australian Open were announced on Tuesday, including two players, although it is not known whether they are active or viral shedding.

Spain's Roberto Bautista Agut was the latest player to earn criticism in the Australian media for complaining about the quarantine conditions.

The world number 13 was shown by Israeli TV channel Sport 5 likening the conditions to jail and saying the restrictions were a disaster.

He subsequently issued an apology on social media, saying it was a private conversation that had appeared in the media without his consent.

Yulia Putintseva of Kazakhstan has been one of the most outspoken complainants and she posted a picture of herself on Instagram holding up a sign reading: "We need fresh air to breathe."

The critics have received the most publicity but there are plenty of players who have accepted the restrictions without complaint and appreciate how their situation looks to Melburnians, who endured the strictest lockdown in the world to reduce community cases to zero.

Two-time former Australian Open champion Victoria Azarenka wrote in a long Twitter post addressing her fellow players: "This has been a very difficult time for a lot of us that did not expect to end up in the situation we are in today, myself included.

"To be in a 14 day hard quarantine is very tough to accept in terms of all the work that everyone has been putting in during their off-season – to be prepared for playing our first grand slam of the year.

"I understand all the frustration and feeling of unfairness that has been coming and it is overwhelming.

"We have a global pandemic, nobody has a clear playbook of how to operate at full capacity and without a glitch, we all have seen it last year. Sometimes things happen and we need to accept, adapt and keep moving!

"I would like to ask all my colleagues for cooperation, understanding and empathy for the local community that has been going through a lot of very demanding restrictions that they did not choose, but were forced to follow."

Tournament director Craig Tiley insisted the majority of players are accepting of the situation and also leapt to the defence of Novak Djokovic following criticism of the world number one.

Djokovic was reported to have issued a list of demands to improve the lot of the 72 players, earning short shrift from Victorian premier Daniel Andrews.

Tiley told Channel 9 TV: "In the case of Novak, he wrote a note, these weren't demands, they were suggestions, but he is understanding what two weeks of lockdown means.

"I think the reports we're seeing and things we are seeing doesn't represent the entire playing group. For the most part, they have been really good."

There had been suggestions the men's tournament could be reduced from best of five sets to best of three because of the limited preparation but that is not in Tiley's plans.

He said: "We are a grand slam at the end of the day. Right now, three out of five sets for the men and two out of three sets for the women is the position we plan on sticking to."

Andy Murray is continuing his isolation at home in Surrey after testing positive for coronavirus and it is hoped he will find out in the next day or two whether he will be able to travel to Australia.
