There are 2,182 confirmed cases of the virus in NSW More than 100,000 COVID-19 tests have been conducted in NSW

The person had been admitted to Orange Base Hospital but died today.

The Western NSW Local Health District said at the request of the family, no further details would be released.

A 95-year-old woman died yesterday at the Dorothy Henderson Lodge aged-care facility in Sydney.

The woman was the fifth resident at the aged-care facility in Macquarie Park to die after contracting the virus.

Australia now has 21 COVID-19 deaths.

There are also 150 new coronavirus infections in NSW, taking the state's total to 2,182.

NSW Premier Gladys Berejiklian confirmed more than 100,000 COVID-19 tests had been performed across the state, and added testing was being ramped up.

But she also warned that NSW would not be able to control the spread of the virus and said it was up to individuals to remain vigilant.

"We can't let our foot off the pedal, we can't relax," Ms Berejiklian said.

"Do not look at the number of cases and whether they are up or down on a day, because it doesn't take long, it doesn't take much for things to get out of control.

"At this stage we are still, to an extent, controlling the spread but we know we can't do that forever.

"This virus is virulent, it spreads really, really quickly and unfortunately too effectively and therefore we have to maintain our vigilance."

BaptistCare, which operates the Dorothy Henderson Lodge, confirmed 16 residents and five staff members had now contracted COVID-19.

"It is heartbreaking to learn of another resident passing away," CEO Ross Low said.

"To be faced with this loss is incredibly difficult, especially knowing just how hard everyone is working to care for our residents and staff."

NSW Police confirmed they would continue to quarantine returning Australians in hotels for 14 days, with another 700 arrivals expected at Sydney Airport today.

Police Commissioner Mick Fuller said while there had been complaints from some of those forced into hotel quarantine, most people understood why it was necessary.

"We shouldn't frame everyone in these hotels as people who are ungrateful because that's certainly not the case," he said.

"Every day we get through, they are a day closer in terms of going home."

Commissioner Fuller said police had yet to issue any fines for breaches of the state's tough new lockdown laws and said officers would use their discretion when enforcing the measures.

"We understand these changes can be difficult ... and we will continue to work and give you our best advice and guidance," he said.

"I know there will always be what-ifs that will be challenging but the message is simply ... small numbers are safe, stay home when you can."

Businesses across NSW are being urged to "re-tool" so they can manufacture desperately needed medical supplies like hand sanitiser and masks.

Ms Berejiklian announced government support will be available for companies who can help meet the demand.
