An apartment block in Sydney's south-west, the current epicentre of the coronavirus outbreak, has been locked down.
The building in Liverpool has notched up over a dozen positive COVID-19 cases, prompting authorities to take action.
"There are fourteen confirmed cases of COVID-19 who live in an apartment block at 29-33 Campbell Street in Liverpool," a South Western Sydney Local Health District spokesperson said in a statement.
"Further investigation is on-going to determine the number of affected households."
All residents in the block are now considered close contacts and are required to isolate for 14 days and undergo repeat testing.
"Testing of residents will be done in their apartments, as they cannot leave during their isolation period," the spokesperson added.
"The NSW Police Force and private security are ensuring the safety of the building. Food and other services, including daily welfare checks, will be provided to residents safely during their 14-day quarantine period."
Authorities say the outbreak serves as a reminder to other Sydneysiders living in complexes.
"This situation reinforces the need for everyone to wear a face mask in shared foyer or lobby areas, lifts, stairwells and corridors, and shared laundry facilities of apartment complexes".
The news comes as NSW braces itself for large numbers of new cases again across the weekend.
NSW Premier Gladys Berejiklian warned the worst is yet to come in terms of case numbers, despite weeks of lockdown.
"I do want to foreshadow that given this high number of cases, we are likely to see this trend continue for the next few days … I am expecting higher case numbers in the few days and they just wanted want to be prepared for that," Ms Berejiklian said yesterday after announcing another record of new daily cases.
There were 291 cases diagnosed in the 24 hours to Friday, with at least 50 of those infectious while in the community.
