The head of the Australian Medical Association (AMA) has called for a tighter lockdown in Sydney.
Dr Omar Khorshid said there should be more consistent rules across Greater Sydney.
At present eight council areas have stricter measures in place than the rest of Sydney.

"Lockdown should mean lockdown across the whole Sydney region," Dr Khorshid said.
"COVID-19 does not respect geography or local government boundaries on a map, and clear and simple rules applied everywhere will make a difference -- including mandatory mask wearing indoors and outdoors, when outside the home."
Dr Khorshid said there was a risk New South Wales would have to live with the Delta strain for the foreseeable future.
"We know how difficult this is for the Sydney community, but the alternative is months of lockdown or having to face the enormous human toll inflicted by this terrible virus in other parts of the world.

"We don't know if it will be possible to eliminate the Delta strain from Sydney, but the benefits of doing so will be enormous and worth the inconvenience, disruption and real hardship being faced by all of Sydney at the moment."
Dr Khorshid called on people to stay at home in Sydney rather than going to a lockdown protest.
"Don't do it. If you are there, you are part of the problem. You are going to extend the lockdown you are so against," Dr Khorshid said.
"If you want to be part of the solution, go get the vaccine and stay at home."
