NSW has recorded six new coronavirus cases, including five returned travellers, for the second day in a row.
The five travellers are in hotel isolation and the sixth case, a man in his 70s from the Penrith area, is under investigation and all close contacts have been contacted.
A record 23,733 tests were notified in the latest reporting period, up until 8pm on Friday, compared with 15,278 and 17,175 tests in the previous two 24- hour periods.
NSW Health re-issued advice not to travel to Melbourne "hot spots" and continues to urge anyone feeling unwell - even with the mildest of symptoms such as a runny nose or scratchy throat - to practice good hygiene by coughing and sneezing into their elbow or a tissue, washing their hands regularly, isolate themselves from others and to seek testing via their GP or by visiting one of the COVID-19 testing clinics.
