The number of confirmed cases of COVID-19 in the Illawarra Shoalhaven Local Health District has risen to 114 on Monday.
That is an increase of 11 over the weekend.
Four patients are being cared for in Wollongong Hospital, and two patients are in Shoalhaven Hospital.
The number of cases surpassed 100 on Friday, jumping to 103.
NSW Health has also increased testing where there is evidence of local transmission in several areas including Nowra and South Nowra.
The public health unit is now contacting close contacts of the 11 new cases diagnosed, and asking them to self-isolate for 14 days from last contact.
They will be contacted every day to check that they are well and any contact who develops COVID-19 symptoms will be tested for the infection.
Of the 114 cases, 23 are aged 60 to 69; 21 are 70 to 79; and there is 16 in the 40 to 49, and 14 in the 50 to 59 age groups.

Across the state as at 8pm on Sunday, an additional 57 cases of COVID-19 have been diagnosed, since 8pm April 4, bringing the total number of confirmed cases in NSW to 2637.
NSW Health's Dr Jeremy McAnulty said 57 new cases was a drop on the previous day which was partly explained by fewer tests being done over the weekend.
Two more people died from COVID-19, bringing the state's total deaths to 18.
An 86-year-old man confirmed to have COVID-19 died in Liverpool Hospital. He was a resident of the Opal Care Bankstown aged care facility.
