New South Wales has recorded another six new coronavirus cases, with just one from hotel quarantine.
Five of new cases reported on Wednesday were locally acquired, with the source of infection unidentified.
These include a man and a woman in their 40s who live together in western Sydney, a man in his 60s and a woman in her 50s from south-eastern Sydney and a woman in her 30s from Sydney.
There were 25,874 COVID-19 tests conducted over the 24-hour reporting period, more than double the 10,375 tested on Monday.
The Sydney CBD is on alert after positive cases visited an inner-city shopping centre, an office building on George Street and a gym on Pitt Street.
One of the new infections visited Kmart and the Apple store at Broadway Shopping Centre in Ultimo while infectious from 3.40pm to 4.40pm on Saturday August 22.
Broadway Shopping Centre released an urgent warning for shoppers on Tuesday night, after learning a positive coronavirus infection visited the venue.
‘Any customer who visited these stores during this time should monitor their health and if they develop any COVID-19 symptoms, get tested immediately and self-isolate,’ the centre said.
‘Apple and Kmart are tonight undertaking deep cleaning and working with NSW Health to ensure all other required actions are taken to maintain our community’s safety.
‘Based on current health advice, customers in our wider community who may have visited other retailers in the centre, or visited at other times should not be alarmed.’
Two of the new cases attended City Tattersalls Fitness Centre on Pitt Street in Sydney’s CBD. The gym has been closed for cleaning.
NSW Health said fitness fanatics who visited the venue on August 19, 21 or 23 should keep a look out for symptoms. They are working with the fitness centre to identify close contacts.
A warning has also been issued for Sydneysiders who visited 300 George Street, in the city’s CBD, after a positive case went to work on August 19, 20, 21 or 24.
‘If any develop to get tested and self-isolate immediately, after one of the new cases worked here while infectious,’ NSW Health said.
One of the new infections is a trainee bus drive, who worked one day while infectious.
The bus driver was wearing a mask and had limited contact with passengers.
‘The risk to any passengers is very low,’ Chief Health Officer Kerry Chant told reporters on Wednesday.
NSW Health said there are currently 72 active COVID-19 cases across the state, with seven patients battling the virus in intensive care, including four on ventilators.
Meanwhile, three Sydney schools were closed on Wednesday due to possible cases of students with COVID-19, the Education Department said.
Riverstone High School, Wyndham College, both in Sydney’s northwest, and Schofields Public School in the west, are being deep cleaned while coronavirus tests for the students concerned are processed.
Dr Chant said one Year 12 student had returned a positive result and would be included in Thursday’s case numbers.
One student had an ‘equivocal’ result and will be tested again while two other students returned negative results but would be tested again for extra precaution.
HSC trial exams at Wyndham College will be rescheduled and the school is contacting students who were due to take their HSC drama performance trial on Wednesday.
Premier Gladys Berejiklian reiterated that while COVID-19 case numbers have been low in recent weeks, the state was still in a battle against the virus.
‘Whilst we have been doing well the last few weeks we are by far not out of the woods yet,’ she told reporters on Wednesday.
