Five new cases of COVID-19 have been diagnosed in NSW, including four international travellers in hotel quarantine and one case of local transmission.
NSW Health said on Sunday the local transmission is a close contact of a person linked to Great Beginnings Childcare Centre at Oran Park in Sydney's south-west.
"There are now six cases associated with this childcare centre, and 19 in total in the Oran Park community cluster," a NSW Health spokeswoman said.
"All staff and children who attended Great Beginnings Childcare Centre between 2 and 13 October are considered close contacts and must get tested immediately and self-isolate for a full 14 days from when they last attended."
Anyone who is tested must stay isolated for the full 14 days regardless of their test result.
NSW Health previously confirmed that one of the cases at the childcare centre is an educator who works there. The centre has been closed since October 13 and will remain closed until October 28, with contact tracing and investigations continuing.
The fresh cases were diagnosed between 8pm on Friday night and 8pm on Saturday night, with 12,985 tests done in that time.
Dr Christine Selvey from NSW Health said on Sunday that 73 cases are currently being treated in NSW, including one patient in intensive care who doesn't require ventilation. Most of these cases are in non-acute, out of hospital care.
Dr Selvey said testing clinics remain open on the weekends and people should get tested "on the day that you get your symptoms".
"Don't wait to see if they go away," Dr Selvey said. "Assume it's COVID-19 until proven otherwise by a test. There is no limit on how many tests you can have."
Meanwhile, in Victoria, people in Melbourne will soon be able to visit each other's homes and retail and hospitality will re-open in part from November 2.
Premier Daniel Andrews announced on Sunday that new changes for metropolitan Melbourne will commence from 11.59pm on November 1, including a new measure which will allow a maximum of two people plus dependent children to be able to visit another home once a day.
The "four reasons to leave home" – essential shopping, exercise, medical/compassionate care and work or education – will also be removed from November 2.
Mr Andrews said the new visiting rule would be "not a bubble, not an exclusive arrangement, but essentially one family, two adults and children, to your home once a day – no more often than that".
