NSW has recorded its highest number of daily COVID-19 cases in almost four months, with authorities reporting 22 positive test results in the 24 hours to 8pm on Monday.
One of the cases has not yet been linked to a known source, while four were overseas travellers in hotel quarantine and one was acquired in Melbourne.
The remaining 16 were linked to known outbreaks, NSW Health said.
This is the largest number of new infections reported by NSW Health in one day since April 16, when the deadly Ruby Princess and Newmarch House outbreaks were continuing and the state was still in lockdown.
Then, 29 cases were reported, with most linked to the aged care home and cruise ship.
Eight of the new cases were linked with Tangara School for Girls - including five students, a staff member and two social contacts of confirmed cases.
There are now 17 cases (including 11 students) associated with the private school and the original source of this cluster remains under investigation.
Two of today's cases are contacts of a previously reported case from the Batemans Bay Soldiers' Club, which brings the number of cases linked to that outbreak to 10.
One of the two cases is a student at Batemans Bay High School while the other attends Batemans Bay Public School. The schools are closed today for cleaning, and contact tracing is under way.
A student from Our Lady of Mercy College at Parramatta - mentioned in yesterday's report - was included in today's numbers, and a further two students, who were close contacts at the school, have now tested positive.
One case was associated with the Thai Rock Wetherill Park restaurant cluster, which now has 112 linked cases.
Three of Monday's cases were close contacts of a previously reported case, and another was a household contact of the case acquired in Melbourne.
NSW Health said there were 13,257 tests reported in the 24-hour reporting period, compared with 19,920 in the previous 24 hours.
"As COVID-19 continues to circulate in the community, maintaining high rates of testing is vital at this time, and NSW Health urges anyone with even the mildest symptoms to come forward for testing," the health department said.
There are currently 117 COVID-19 cases being treated by NSW Health, with eight patients in intensive care and six ventilated.
