There were 205 new COVID cases detected in the Shoalhaven during the 24 hours to 8pm last night - 66 in the 2541 area, 92 in 2540, 32 in 2539, six in 2538 and nine in 2353.
There were also 58 new cases in Kiama - the vast majority in the 2533 postcode.
They were among 1448 cases in the Illawarra Shoalhaven Local Health District, and 25,870 across the state as the number of people undergoing PCR testing continues to fall.
NSW Health says as people increasingly follow the advice to use rapid antigen tests for diagnosing COVID-19, the number of PCR tests will underestimate the true number of people who have tested positive for COVID-19.
There are currently 2,186 COVID-19 cases admitted to hospitals across the state, with 170 people in intensive care, 51 of whom require ventilation.
The 24 hours saw the deaths of 11 people with COVID-19 - six women and five men.
Seven people were aged in their 80s, three people were aged in their 90s, and one person was aged in their 70s.
Of the 11 people who died, nine were vaccinated and two were not vaccinated.
Four people were from south western Sydney, one was from western Sydney, two were from the Hunter Region, one was from eastern Sydney, one was from northern Sydney, one was from Southern Sydney, and one was from the Central Coast.
Meanwhile the number of COVID patients hospitalised in the Illawarra Shoalhaven Local Health District has more than tripled in the past week.
On January 4 just 23 were in the district's hospitals, one week later that number had ballooned to 74.
The growing number of COVID patients has resulted in the health district extending through to February a suspension of all non-urgent elective surgery requiring an overnight stay in hospital.
