Northern Sydney Datacom workers in self-isolation, NSW reports five new local COVID-19 cases

Staff on a floor of Datacom's northern Sydney office building have been told to self-isolate after a co-worker tested positive for COVID-19 as New South Wales reports five new local cases of the coronavirus.

As reported by the Sydney Morning Herald and confirmed to the publication by Datacom CEO Greg Davidson, a COVID-19 case worked at the North Ryde call centre while infectious.

As such, all staff on the floor the infectious case worked on have been directed to self-isolate and get tested until further notice.

Davidson also told the Sydney Morning Herald that most of the employees in the North Ryde office had been working from home, but some roles required staff to work in the office.

The publication also confirmed that staff directed to self-isolate are doing so on full pay.

It comes as NSW confirmed 10 new cases of COVID-19 today including five locally acquired cases and five returned travellers in hotel quarantine.

According to NSW Premier Gladys Berejiklian all five of the locally acquired cases are connected to already known cases or clusters.

Four of the five are associated with the private health clinic cluster, three are household contacts of a case reported yesterday, and one is a co-worker of a case reported yesterday.

There are now seven cases associated with the private health clinic cluster, and investigations into its source are ongoing.

One of the locally acquired cases included in today's numbers is an old case and was most likely acquired back when the virus was circulating in low levels in south-western Sydney in August according to NSW chief health officer Dr Kerry Chant.

The COVID-19 update from NSW follows a number of public health alerts issued yesterday including for the Monopole Restaurant in Potts Point and for Macquarie University.
