Mr Barr said he had concerns about Prime Minister Scott Morrison's "war footing" rhetoric that followed the announcement national cabinet would meet twice weekly.

Mr Barr said he wasn't opposed to more frequent meetings but he would reserve the right to absorb information and listen to experts before making decisions.

"There does need to be time between meetings in order for relevant information to be prepared and for state and territory leaders, and the Commonwealth, to be able to have some time to absorb the information that is coming forward," Mr Barr said.

However, the Chief Minister acknowledged the need to address issues with the coronavirus vaccination program.

"There is a degree of urgency, clearly, about getting the Australian vaccination program back on track - but we do not need a panicked and rushed response," Mr Barr said on ABC radio on Friday.

"I want to hear from experts and the obvious issue at the moment is not our capability around delivering vaccines, it's the supply of them."

Mr Barr said the biggest factor slowing Australia's vaccine rollout remained securing supply, the responsibility of the Commonwealth, rather than delivery capability.

"The Commonwealth doesn't have a fantastic track record of program delivery, and so now the reason we're having all these national cabinet meetings, is that the ball is being thrown, or the parcel is being passed to the states and territories to try and rescue this national program," he said.

"We, like the other states and territories, will stand ready to work in support to assist in the delivery."

NSW Premier Gladys Berejiklian has said she is happy to take part in more national cabinet meetings but only if the federal government improves transparency about vaccine supplies.

The next national cabinet meeting has been brought forward to Monday and after that will convene twice a week as it seeks to rectify Australia's COVID-19 vaccination program.

The federal government this month dumped its vaccine rollout timetable, which sought to have all Australians vaccinated by the end of October.

Mr Morrison said the more regular meetings would continue "until we solve the problems and get the program back on track".

The federal government this week confirmed Australia would need to shift to mass-vaccination clinics to be run by the states and territories, however no Commonwealth funding would be provided for the program.
