Uniting Wontama Orange service manager Helen Mobbs said family members were contacting residents from the car park area to at least be able to see and talk to them on a balcony or through a window.

Mrs Mobbs said visits to the 160 aged care residents at Uniting's Wontama and Parkwood centres were being strictly limited.

"Our residents' families are unable to come in and visit their loved ones at the moment. We have a pause on visitation rights," she said.

Mrs Mobbs said exceptions were being made on a case-by-case basis, particularly if a resident was close to the end of their life.

"We've had a couple. We're fully supportive of people. We have crossed those circumstances," she said.

Mrs Mobbs said family members had also brought Easter gifts and flowers to the reception area for staff to pass onto residents.

"They just can't do that themselves," she said.

Mrs Mobbs said staff were also helping residents set up electronic devices to enable them to be in contact with family through social media including Face Time and Skype.

She said residents were not confined to their rooms and were able to move around and use the centre's facilities.

"They're still dining together," she said.

Mrs Mobbs said social distancing was being monitored to reduce risks of people contracting the coronavirus.

"For a lot of residents the normal-day life has changed so much," she said.

The visitation policy is being reviewed every two weeks.

In Sydney Anglicare's Newmarch House aged care facility near Penrith is in lockdown after a staff member went to work there for six days with symptoms including a sore throat.

She has since tested positive for the coronavirus along with five other staff members and four residents at the facility.

About 100 residents, with an average age of 85, are having to isolate in their own rooms.

About 40 staff at the facility have also been stood down to self-isolate at home.

NSW chief health officer Dr Kerry Chant said the worker was "mortified" by what had happened.
