65 new NSW COVID-19 cases, numbers could rise tomorrow: Premier

NSW Premier Gladys Berejiklian said there were 58,000 tests across NSW in the 24 hours to 8pm last night which was a "great result" and she said we could be seeing signs of the latest outbreak stabilising.

She said while the 65 positive community cases was a "welcome drop", "it comes with a warning".

Twenty-eight of those cases were infectious in the community.

"I am predicting we will have higher case numbers tomorrow," Ms Berejiklian said.

She urged NSW residents to continue to follow the health orders and stay at home unless they need to go out for essential reasons.

"Make sure you stay at home and only leave the house if you absolutely have to," she said.

She also reminded residents not to turn up at GPs or chemists if they have symptoms, but instead to call ahead first.

"If you have symptoms the only place you should be going is to get tested and stay isolated," she said.

"My overwhelming message to the community is to keep doing what you're doing.

"Keep limiting your mobility, keep sticking to the rules, because it's having an effect.

"We are now in a stage of stabilising, but we need to do better than that to come out of the lockdown - we need to see a decline."

NSW chief health officer Dr Kerry Chant said the 28 cases that were infectious in the community was "too high and we need to see this number go down".

She said people should get tested on the first day they notice symptoms - don't wait overnight to see if it will go away.

She said if you have symptoms or are isolating and you need paracetamol or other medications, call the chemist or have someone from another household pick the medication up and drop it at your door without coming in contact with you.

She said Emu Plains and Cumberland were among areas of increased testing and spoke of a COVID-19 positive resident in Emu Plains who was infectious in the community.

"This is an unlinked contact and is under investigation," she said.

Anyone who was at Lennox Shopping Village and/or Woolworths inside the Lennox Shopping Village on Saturday, July 10 from 3.45pm to 5pm is a casual contact and must get tested and isolate until they have a negative result.

Anyone who was at those locations between 4pm and 4.45pm is a close contact and must immediately get tested and self-isolate for 14 days regardless of the result, and call 1800 943 553 unless they have already been contacted by NSW Health.

Dr Chant urged anyone in Emu Plains to come forward for testing.

NSW Health Minister Brad Hazzard said "This virus is only moving around if people are moving around. That's why the health orders direct us to stay at home and leave only under particular circumstances."

He said people could go to work if they couldn't work from home but employers should be facilitating their staff to work from home "if at all possible".

There are no new health alerts for Hawkesbury today, but there were three earlier this week, as follows: Windsor Coles, in the Windsor Riverview complex, at 223 George Street from 1:20pm to 3pm on Saturday, July 10; McGraths Hills BMX Track on Bismarck Street from 11am to 1pm on Wednesday, July 7, and Windsor Riverview Shopping Centre at 227 George Street from 1:30pm to 3pm on Wednesday, July 7. All are casual contact sites.
