New South Wales has recorded more than 300 new cases of coronavirus as the number of Omicron case grows in Sydney.
Another 325 cases and one new death were confirmed by health authorities on Saturday.
There are currently 139 people being treated in hospital for the virus, with 25 in intensive care.
Meanwhile, 13 cases of COVID have been linked to a cluster at a western Sydney school, with at least three of those cases confirmed to be Omicron.
The three confirmed cases in students at Regents Park Christian School takes the number of confirmed Omicron cases in NSW to 13.
The first student to test positive for Omicron had no link to overseas travellers, stoking fears the new strain is circulating in the community.
All staff and students at the school are close contacts and are required to get tested and isolate.
NSW Health is “urgently investigating” the source of infection for the school cluster.
“This is of concern to the extent that this is the first case that we know of that appears not to have had any travel history,” Health Minister Brad Hazzard said.
“It would appear that the case could well be an on-NSW-soil transmission.”
Students from the school have already been dismissed for the year, but contact tracing and further investigations are underway.
Currently, 92.7 per cent of the population in NSW aged over 16 is fully vaccinated, with 94.6 per cent having received their first dose.
NSW COVID-19 update
Despite the rise in case numbers, Premier Dominic Perrottet is urging the public to instead focus on hospitalisations and ICU presentations.
“We would have expected those (case) numbers to be much higher in circumstances where we opened up our state,” he said on Friday.
The jury is still out on the severity of the Omicron variant, and whether it causes a more severe disease that could overwhelm hospital systems or is merely more transmissible but potentially less dangerous.
