There were 32,580 tests reported in the 24-hour reporting period, compared with 28,767 in the previous 24 hours.
Health authorities warned that while case numbers have remained low this week the virus continued to circulate in the community and vigilance must be maintained.
"It is vital that high rates of testing continue in order to find the source of the cases still under investigation and to identify and stop further spread of the virus," a health spokeswoman said.
"NSW Health is urging anyone with even the mildest of symptoms - including runny nose, sore throat, cough, or loss of taste and smell - to come forward for testing.
"It is the best way to protect your family, friends and the wider community.
"If you have any cold or flu-like symptoms at all, assume it's COVID-19 until proven otherwise - isolate and get tested right away; don't delay."
