For the second day in a row, there have been no new cases of coronavirus involving community transmission in NSW.
The six new cases recorded in the 24 hours to 8pm on Tuesday were all returned overseas travellers, who are in hotel quarantine.
The last time NSW had consecutive days without community transmission was July 3, 4, and 5.
Test numbers in the last 24-hour reporting period jumped to 16,759 following two days of sub-10,000 figures.
"While there were no locally acquired cases recorded in the past 48 hours, the virus is likely still circulating and it is imperative anyone displaying mild symptoms get tested immediately and not delay their test," a NSW Health statement said.
"Testing numbers were higher today, but they have declined in recent weeks.
"NSW Health is appealing to the community to come forward for testing right away if you have a runny nose or scratchy throat, cough, fever or other symptoms that could be COVID-19.
"If people don't come forward and get tested, we can't keep the pandemic at bay.
"We would like to see testing levels above 20,000 as achieved last week, particularly in South Western Sydney, and ahead of school holidays.
"For the sake of your friends and family, get a test. And if symptoms recur even a few days later, test again. It's free.
"NSW Health continues to strongly encourage people to wear masks when unable to physically distance, particularly in indoor settings and on public transport.
"As previously advised, when taking taxis or rideshare commuters should sit in the back and wear a mask."
