Kei Nishikori, the 2014 U.S. Open runner-up, and two-time Australian Open champion Victoria Azarenka were among a group of players who arrived on the flight from Los Angeles.
British player Heather Watson said on Twitter that she and others who arrived from Abu Dhabi are NOT allowed out (of) our rooms. She posted the notification that she and others who were on the flight received informing them of the quarantine.
The Chief Health Officer has reviewed the flight and has determined that everyone on board needs to isolate and will be confined to their rooms for the 14-day quarantine period, said the notification, which Watson posted.
Being unable to leave their room would mean the only workouts theyd be able to have would be on an exercise equipment left in the rooms of all of the players.
Other players will be allowed to train under strict conditions and with supervision for up to five hours a day, although those practice sessions in Melbourne had been delayed while health authorities waited to receive all the coronavirus tests.
Several players in quarantine, including Sorana Cirstea of Romania, Belinda Bencic of Switzerland and Yulia Putintseva of Kazakhstan complained in social media posts that the rules seemed to have changed between what they saw before traveling to Australia and what was being imposed in Melbourne.
I agree…if they would have told us this rule before i would not play Australia…I would have stayed home. They told us we would fly at 20% capacity, in sections and we would be a close contact ONLY if my team or cohort tests positive .

Tiley said there were no plans to delay the Australian Open any further its already starting three weeks later than usual.
Australias international borders are basically closed to travelers, although there are exemptions in special circumstances.
Australia has done a relatively good job of containing the coronavirus, with 909 deaths nationally.
