NSW Health has appealed for people not to "overwhelm" new coronavirus testing centres, one of which is at Sutherland Hospital.
Another of the officially named COVID-19 / Flu assessment clinics is due to open at St George Hospital on Thursday.
The Sutherland Hospital clinic opens from 8am-8pm, seven days a week.
NSW Health released images of the inside of one of the new clinics at Royal Prince Alfred Hospital while making an appeal for people to exercise judgment.
"We stress these clinics are for those most at risk with respiratory symptoms or fever, those returning from overseas or in contact with a COVID-19 case, or people like our health workers," a NSW Health statement said.
"It is vital that these respiratory clinics are not overwhelmed with people who are not in the high risk groups, which could result in delays identifying those most vulnerable.
"These clinics are currently assisting with the assessment and testing of people with fever, cough or flu-like symptoms who are returned travellers or a contact of a confirmed case."
Another 39 cases of COVID-19 were diagnosed in NSW in the 24 hours to 11am on Tuesday, taking the total to 210.
A total of 28,552 people have tested negative.
NSW Health revealed the 30-39 age group has the highest number of coronavirus cases in NSW and there is an almost equal representation of males and females across the board.
The breakdown of cases is seen in the table below:
The statement said everyone should practice social distancing, as it reduces the potential for transmission.
"Social distancing is an effective measure, but it is recognised that it cannot be practiced in all situations and the aim is to generally reduce potential for transmission.
"While practicing social distancing, people can travel to work (including public transport).
"For non-essential activities outside the workplace or attendance at schools, universities and childcare - social distancing includes:
- avoiding crowds and mass gatherings where it is difficult to keep the appropriate distance away from others
- avoiding small gatherings in enclosed spaces, for example family celebrations
- attempting to keep a distance of 1.5 metres between themselves and other people where possible, for example when they are out and about in public place.
- avoiding shaking hands, hugging, or kissing other people
- avoiding visiting vulnerable people, such as those in aged care facilities or hospitals, infants, or people with compromised immune systems due to illness or medical treatment."
