This figure brings the overall count of positive infections in the city to 96 cases since the virus resurfaced earlier this month on December 2.

Including the city's 11, Western NSW Local Health District released a total of 20 cases across the district, with the remaining cases again spread out across the region.

The 11 cases in Orange are joined by reports of three cases in the Mid-western LGA (two in Mudgee, and one in Gulgong), another three cases in the Cabonne LGA (one case reported with a Molong address), two Dubbo LGA cases, and a single infection in Parkes.

In an announcement from Orange City Council, the Yarrawong Preschool and Early Child Care Centre will remain closed today, December 20.

The decision from council follows the report of a positive case at the centre last week on Tuesday, December 14, to allow for processing time around close contact tracing, and to ensure the safety of both staff and children.

Residents of Gossling Creek's Aged Care Facility in Orange remain under lockdown conditions, restricted to rooms until the facility's management is given clearance by the local public health unit.

Despite the statewide figure breaking regular case records, NSW premier Dominic Perrottet advised that mask mandates (among other restrictions) wouldn't be reintroduced; that these agenda items boiled down to "personal responsibility".

"As we're heading into this Christmas period ... there's no doubt shopping centres will be busier, we just say please take personal responsibility," Mr Perrottet said.

Chief Health Officer Dr Kerry Chant's professional health advice was at odds with the government's decision, stressing the importance when it comes to the use of ongoing mask use.

"Because we're asking people to take personal responsibility, that's a matter for government in setting those mandates," Dr Chant said.

"And all I'm saying - from a public health decision - is I'm strongly recommending we keep masks."
