Shadow health minister Ryan Park this week said it didn't make sense for the government to tell people not to come forward for COVID tests, and that a plan is "urgently" needed to increase testing facilities.

"[We need] a plan to increase the testing facilities, a plan to make sure that our hospitals are adequately resourced and a plan to make sure that we can boost our vaccination levels and ensure that everyone gets access to that important booster," he told reporters on Tuesday.

Mr Park said that the state is "in the middle of a health crisis" and that health minister Brad Hazzard was not demonstrating leadership when he said 'pretty well everyone' in NSW will catch Omicron at some point.

He believes the state government must reach out to the Commonwealth for additional testing resources as healthcare workers across the state work to process roughly 150,000 tests per day.

Premier Dominic Perrottet said the shadow minister's comments were "utterly irresponsible" and that the state's healthcare system is "doing incredibly well".

"We don't need to be instilling fear in the community, but hope and optimism," he said.

Mr Perrottet argues that other states are closing their borders "because they don't have faith in their health system".

When asked what is being done to support the state's healthcare staff currently working long hours to keep up with testing demand, he said "billions" of dollars have been invested into healthcare across the board.

"Everyone has made enormous sacrifices over the last two years and continue to do so, and we want to provide whatever support we can to NSW Health," Mr Perrottet said.

"I have complete confidence in the strength of our system."
