Four coronavirus cases – one of whom Victoria's Chief Health Officer Brett Sutton said was believed to be a player – linked to the Australian Open were confirmed by officials on Monday. A member of the air crew on one of 17 flights chartered by tournament organisers also tested positive to the virus.
Infectious disease experts have warnedmore cases are "very likely" in the coming days as COVID-19 could still be incubating in some of the 1200 tennis players and officials.
More than 15,500 Victorians were tested for the virus in the 24 hours before midnight on Monday.
Victoria treating western Sydney as'second-class citizens':mayor
Meanwhile,travel restrictions remain in place forlarge areas of regional NSW that have not recorded a coronavirus case for months,despite an Andrews government move to relax the hard border closure for people in some parts of Sydney.
Parts of Sydney's"red zone"were downgraded at 6pm on Monday to orange and all border towns are now green zones,paving the way for some Victorians now stranded in NSW to return home without special exemptions.
Anyone in an orange zone can travel home,but must quarantine until receiving a negative test result,while anyone in a red zone cannot enter Victoria.
The 10 Sydney local government areas still classified as red zones are all in western Sydney.
One western Sydney mayor says his residents are being treated as"second-class citizens"by Mr Andrews.
Fairfield City mayor Frank Carbone said he cannot see why his local government area is still being treated as a red zone given it has not had a new case of COVID-19 for almost 90 days.
"It is quite clear that it seems that if you hold a tennis racquet these days,it has a lot more power than having an Australian passport,"Mr Carbone told theToday show on Tuesday morning.
"I don't want western Sydney to be treated as second-class citizens and I will always stand up for my community because I'm very proud of what Fairfield has achieved. We've had the virus before and overcome it."
NSW Premier Glady Berejiklian echoed his sentiments,saying Victoria should have reopened to Sydney"a long time ago".

"I don't really understand the traffic light system,"Ms Berejiklian said.
"The 10 local government areas that are still having that restricted arrangement[would be] around a million people,"she said,calling on other state leaders to"base[their] decisions on the science and the facts".
"There is currently no part of Australia that is a hotspot,therefore there should be no border which is closed to Australian citizens."
Mr Andrews said there was a"real chance"that the current status of Brisbane could change from orange to green in the near future.
"If they stay on the path they're on now,then hopefully we can have them green and indeed hopefully we can have NSW green very soon as well,"he said.
But he said daily analysis of the 10 remaining red zones within Greater Sydney was a priority"so everybody who needs to come home can come home".
"Then we can we can talk about what the green status of different parts of the country[is],"Mr Andrews said.
Tuesday marks exactly a year since Australian health authorities went public with their concerns about a mystery illness emerging in China that,unbeknown to them at the time,would claim 909 Australian lives.
