She said it was vital anyone in these LGAs with respiratory symptoms present for COVID-19 testing.

While the Lithgow LGA might have been added to the statewide list of hotspots on Monday, NSW Health information on this area has not been updated since Saturday.

At 8pm on Saturday, the Lithgow LGA was still listed as having between 1-4 confirmed COVID-19 cases, while 25 people in the Blue Mountains LGA have tested positive.

"It is critical that the community continues to come forward for testing as we consider changes to restrictions and other matters," Dr Chant said.

"It's important that we have very high levels of testing."

While there are hotspot areas across NSW, she urged anyone with respiratory symptoms to come forward for testing.

The only other regional area to be listed as a hotspot was Goulburn-Mulwaree LGA, with all other LGAs located in Sydney, they include: Hornsby, Lane Cove, Northern Beaches, Blacktown, Canada Bay, Cumberland, Inner West, Liverpool, Parramatta, Ryde, Randwick and Waverly.

Dr Chant also reminded those who work in health care or with vulnerable people and who have minimal symptoms to get tested.

"It's critical that you come forward for testing as we know that the early detection of COVID-19 prevents and is a critical element of preventing further spread," she said.
