Health Minister Brad Hazzard says those who choose to be unvaccinated are taking up more ICU places than they should as New South Wales records more than 6,000 cases for the second consecutive day.
Mr Hazzard said while studies have indicated Omicron is less severe than other variants it nevertheless has an impact on the unvaccinated.
"The majority of people who are in intensive care in New South Wales and requiring health staff to be looking after them, putting them at risk also, are people who have not been vaccinated," he told a media conference on Sunday.
"So the unvaccinated are ... taking more places than they should be in our ICUs simply because they have chosen not to be vaccinated."
