One new COVID case in the Shoalhaven's 2539 area, detected during the 24 hours to 8pm on Sunday, has been linked to a known case.
The 24 hours also brought one case in the Kiama local government area, four in Shellharbour and 18 in Wollongong.
At 8pm on Sunday the number of COVID patients being treated in the Illawarra Shoalhaven Local Health District's hospitals had fallen by two to six.
They have taken the number of COVID cases in the health district since June 16, when the first case of the current outbreak was reported, to 2904.
While the number of local COVID cases remains relatively low, across the state there were 2501 new cases during the 24 hours.
There are currently 261 COVID-19 cases admitted to NSW hospitals, with 33 people in intensive care, 11 of whom require ventilation.
NSW Health continues to remind everyone across the community to practice COVID-safe behaviours, including recommending wearing a mask in settings where you cannot physically distance.
Around a quarter of people who have been exposed to COVID-19 might still develop their infection after seven days.
For the next seven days close contacts should exercise caution and not enter high-risk settings, should avoid large indoor gatherings, use a Rapid Antigen Test if coming into contact with vulnerable people, and should get tested again on day 12.
The NSW Health advice is to get tested and stay home if you have the mildest of symptoms; don't go out and visit family, friends or go to social events if you are unwell, and practice good hand hygiene by washing and sanitising your hands regularly.
If you do not have symptoms, consider using a Rapid Antigen Test before going out.
