NSW has recorded six new cases of COVID-19 in the last 24 hours and the only case of local transmission was already in isolation.
Five of the new cases are returned travellers in hotel quarantine.
One was a household contact of a previous case who attended Liverpool Hospital and they were already self-isolating.
There are now 21 cases linked to the hospital in Sydney's west.
Almost 17,000 tests were completed in the reporting period, compared to 20,411 the previous day.
NSW has now conducted over 2.5 million tests, according to NSW Health's Jeremy McAnulty.
"Which is great news," he said.
Further testing is underway in the Murrumbidgee Local Health District after a resident tested positive initially but returned a negative result in a second test.
"NSW Health is taking a cautious approach and the individual and close contacts will remain in isolation, while further testing is undertaken," a statement said.
Dr McAnulty said while the number of locally acquired cases remained very low in NSW, the virus was likely still silently circulating in the community.
"As such, the risk of outbreaks and a resurgence of cases remains," he said.
The Queensland Government today rejected NSW Premier Gladys Berejiklian's claim that talks with Queensland Premier Annastacia Palaszczuk about reopening the border had ground to a halt.
Queensland Health Minister Stephen Miles sought to reassure the public there was "strong ongoing collaboration" between the states.
"As there needs to be, we share a highly populated border."
He declined to comment on the personal relationship between Ms Berejiklian and Ms Palaszczuk but said communication certainly had not stalled.
"I know that [Queensland Chief Health Officer] Jeannette Young speaks with the NSW Chief Health Officer pretty much every day.
"And I speak with the NSW Health Minister on most days as well."
This morning Queensland announced it would reopen its border to the Australian Capital Territory next Friday but NSW would remain a hotspot.
