An additional 10 cases of the Omicron strain of COVID-19 have been recorded in New South Wales, with nine being locally-acquired infections and one a returned traveller from overseas.
NSW Health confirmed the total number of Omicron cases in the state has now grown to 25.
It comes as the state recorded 208 new cases of COVID-19 in the past 24 hours to 8pm last night.
The nine new local Omicron cases are linked to the Sydney Indoor Climbing Gym cluster in Villawood, South Western Sydney, with the outbreak also spreading to two schools.
“NSW Health continues to investigate the source of infection of a cluster of COVID-19 cases at Regents Park Christian School, St Peter Chanel Catholic Primary School in Regents Park, and the Sydney Indoor Climbing Gym in Villawood in South Western Sydney,” a NSW Health statement read.
“Genome sequencing carried out on Sunday 5 December shows an additional nine cases in this cluster carry the Omicron variant.
“This brings to 14 the total number of Omicron cases linked to the Regent’s Park Omicron cluster.”
NSW Chief Health Dr. Kerry Chant thanked the school community for adhering to the health advice as contact tracers race to get on top of the outbreak.
A coronavirus case in the ACT has also been linked to the gym cluster.
The ACT resident is believed to have acquired infection by attending the climbing gym on Saturday, November 27.
The gym has been listed as an exposure site, with anyone who attended the centre on that date between 9am and 4.30 pm being considered a close contact.
Close contacts must get tested and isolate for seven days.
There are 152 COVID-19 cases in hospital, with 24 people in intensive care and five patients on ventilators.
None of the cases with the Omicron variant are in hospital.
