New South Wales has recorded nine new cases of coronavirus in the past the 24 hours, including one mystery case with no known source.
The state’s health department confirmed four of the new cases were from returned travellers, while the other five cases were locally acquired.
NSW health officer, Dr Christine Selvey said one case was of concern as the origin was not yet known.
She also reissued an alert about a case visiting a KFC in the Sydney suburb of Concord on September 6, between 1pm and 1.20pm.
“Anyone who attended this venue at this time is considered a casual contact and must monitor for symptoms and get tested immediately if they develop,” she said.
“After testing, they must remain in isolation until a negative test result is received.”
Two of the new cases are household transmissions linked to the eastern suburbs Legion club cluster.
A further two cases are household contacts linked to the St Paul’s Catholic College Greystones cluster.
Dr Selvey said all four cases had been in self-isolation while infectious.
NSW Health is currently treating 83 COVID-19 cases, six of which are in intensive care with three being placed on ventilators.
In the 24-hour period there have been 14,426 coronavirus tests.
Total confirmed COVID-19 cases in NSW are now at 3977 cases while 54 people have died.
In a press conference held in Sydney’s west on Sunday, NSW Premier Gladys Berejiklian slammed both Queensland and Western Australia’s persistent border closures, despite NSW only recording five COVID-19 cases linked to community transmission.
“Our rates of transmission in New South Wales remains very low,” she said.
“I don’t understand when case numbers are so low, why you would even have borders up. Especiallly when you hear those heart breaking stories of people separated from their relatives.”
Both Northern Territory and South Australia have indicated a path forward to opening up their borders to NSW residents.
Ms Berejiklian said borders should be dropped to ensure the NSW economy caould reach its full potential during the financial downturn, with the country’s most populous state likely to prop up other regional economies through goods and services tax income.
“When you have 25 per cent of the economy out of action in Victoria, the pressure is on NSW … we are the largest generator of GST for the nation,” she said.
“When Queensland and WA do not even consider that … it really concerns me.”
