Ms Berejiklian has hinted that some parts of the state might be freed from lockdown earlier than others.
They include areas outside Sydney.
"If in the next few weeks we find parts of greater metropolitan Sydney like Wollongong, Shellharbour, are doing better, we will do the things we have done in Orange to allow communities to live more freely but it is up to all of us to make sure we do the right thing and speak up when others are not doing the right thing," she said.
NSW yesterday reported 172 community Covid cases - a new record for the current Sydney outbreak.
Of those cases, 60 were infectious while in the community.
It was widely reported this morning that NSW's crisis cabinet reached the decision to extend the lockdown last night.
Nine News' Chris O'Keefe tweeted before the announcement that Georges River and Parramatta would join the growing list of Sydney local government areas where residents are unable to leave – even for work – without a valid exemption.
It’s understood Georges River and Parramatta LGA’s will be added to the list of councils with tighter restrictions too. That means they can’t leave the LGA for the work unless exempted. @9NewsAUS
Infectious diseases expert Peter Collignon told the Today programme this morning that restrictions would remain in place in NSW "for at least a couple of months" – and maybe even longer.
Professor Collignon also said the state needed to get cases down to around 20 per day or less with most of those in isolation for most of their infectious period before freedom could be achieved.
"I think we'll have restrictions for quite a while; you don't just have a lockdown and then stop it all together. So there will be ongoing restrictions I would think for at least a couple of months." #9Todaypic.twitter.com/91Q46qyZnp
Queensland today recorded one new locally acquired Covid-19 case and 19 cases aboard a cargo ship off the state's coast.
The bulk carrier entered the Torres Strait from the Philippines on Monday and alerted authorities to a majority of crew on board being sick, Queensland's chief health officer Jeannette Young said.
Queensland Health provided nurses to test those on the ship, with 19 of the 21 crew members returning positive tests on Tuesday night.
