NSW has reported 580 new locally acquired cases of COVID-19 and 11 deaths as the state gets nearer to reaching the 90 per cent first dosage milestone.

Premier Dominic Perrottet flagged an increase in positive cases would follow the state's re-opening on Monday and urged people to proceed safely.

"What has been key to keeping people safe is our high vaccination rate. We have the highest vaccination rate in the country and importantly we're coming close on that first-dose mark to 90 per cent," he said on Saturday.

Mr Perrottet said the NSW roadmap was more conservative than the federal government's approach.

"We believe that our conservative approach here ensures we keep people safe but importantly gets people back into work as quickly as possible."

"This journey is not over. There is a long way to go and we need to continue that focus."

As of Thursday evening, 89.8 per cent of people 16 and over had received their first vaccine dose, while 71.5 per cent are fully vaccinated.

There have now been 425 deaths since the coronavirus outbreak in June including three women and eight men in the last 24 hours to 8pm on Friday.

There are currently 812 COVID-19 cases in hospital, with 163 in intensive care and 75 who require ventilation.

Chief Health Officer Kerry Chant said vaccine availability had improved markedly in the last few weeks.

"It's important that if you have a delayed vaccination appointment, please try to reschedule it earlier or look for other options," she said.

Dr Chant confirmed authorities were still investigating the source of the new Delta strain identified on Friday with different genomic sequencing.

"We've linked that back to a person who returned overseas but the exact mechanism of how that new Delta strain emerged and got into the community in western Sydney is still under investigation," she said.

But there was no indication the new strain presents any differences regarding transmission, vaccine effectiveness or severity.

The state on Wednesday achieved 70 per cent double-dose vaccination coverage of those aged over 16, clearing the way for restrictions to ease as planned on Monday.

From Monday, a swathe of restrictions will lift for fully vaccinated people across the state.

Ten adult visitors will be allowed in homes, 30 people will be permitted to gather outdoors, and 100 guests can congregate at weddings and funerals.

Shops and hospitality venues can reopen and the five-kilometre from home travel limit will be scrapped.

But as the first Australian state to reach 70 per cent vaccination, NSW is also going to be the first to meet some challenges, the premier said.

The United Workers' Union, which represents many frontline and public-facing workers, is concerned members checking vaccination status could be put in unsafe situations.

Adding to their worry is that the integrated Service NSW vaccine certificate or passport app is not yet ready.

Meanwhile, the Australian Medical Association said changes to the state's plan to emerge from lockdown could overwhelm the hospital system and burn out healthcare workers.

NSW is among the highest COVID-19 vaccinated jurisdictions in the world as it reached another milestone with 90 per cent first dose coverage.

The achievement comes just days away from the state's re-opening on Monday following 15 weeks of lockdown in Greater Sydney.

NSW reported 580 new locally acquired cases of COVID-19 and 11 deaths in the 24 hours to 8pm on Friday.

Premier Dominic Perrottet flagged this would likely cause an increase in positive cases and urged people to proceed safely.

"What has been key to keeping people safe is our high vaccination rate. We have the highest vaccination rate in the country," he said on Saturday.

Despite criticism from doctors the accelerated opening could strain medical resources, Mr Perrottet said the NSW roadmap was more conservative than the federal government had proposed.

"We believe that our conservative approach here ensures we keep people safe but importantly gets people back into work as quickly as possible."

"This journey is not over. There is a long way to go and we need to continue that focus."

As of Friday 90.1 per cent of people 16 and over had received their first vaccine dose, while 72.8 per cent are fully vaccinated.

Chief Health Officer Kerry Chant said every increment above 90 per cent was "just going to be a bit harder," and challenged NSW to match the ACT record of 94 per cent first jabs.

She also waved away questions she was not involved in the changes to the state's roadmap saying she briefed the new premier for close to two hours.

"I respect the government's decisions around multiple inputs but I also note that some of the changes are clearly very low risk," she said.

There have now been 425 deaths since the coronavirus outbreak in June including three women and eight men in the last 24 hours.

There are currently 812 COVID-19 cases in hospital, with 163 in intensive care and 75 who require ventilation.

Facebook Inc has apologised to users for a two-hour disruption to its services and blamed another faulty configuration change for its second global outage this week.

The company confirmed its social media platform, Instagram, Messenger and Workplace were impacted by the latest outage on Friday.

"Sincere apologies to anyone who wasn't able to access our products in the last couple of hours," the company said.

"We fixed the issue, and everything should be back to normal now."

During the latest outage, some users were unable to load their Instagram feeds, while others were not able to send messages on Facebook Messenger.

People swiftly took to Twitter to share memes and jokes about the second service disruption this week.

"Looks like Facebook went to a 3-day work week. Monday and Friday shutdowns?" a Twitter user said

Instagram thanked users for their patience and "for all the memes this week".

On Monday, the social media giant blamed a "faulty configuration change" for a nearly six-hour outage that prevented the company's 3.5 billion users from accessing its social media and messaging services such as WhatsApp, Instagram and Messenger.

The outage on Monday was the largest that web monitoring group Downdetector had ever seen and blocked access to the apps for billions of users, leading to a surge in usage of rival social media and messaging apps.

Moscow officials said Monday's outage showed Russia was right to develop its own social media networks, while EU antitrust chief Margrethe Vestager highlighted the repercussions of relying on just a few big players, underscoring the need for more rivals.

Both the outages piled pressure on Facebook this week after a former employee turned whistleblower accused the company on Sunday of repeatedly prioritising profit over clamping down on hate speech and misinformation.

Facebook has confirmed that some users are having trouble accessing its apps and services, days after the social media giant suffered a six-hour outage triggered by an error during routine maintenance on its network of data centres.

Some users were unable to load their Instagram feeds while others were not able to send messages on Facebook Messenger.

"We're aware that some people are having trouble accessing our apps and products. We're working to get things back to normal as quickly as possible and we apologise for any inconvenience," Facebook said in a tweet

People swiftly took to Twitter to share memes about the second Instagram disruption this week.

Web monitoring group Downdetector showed there were more than 36,000 incidents of people reporting issues with photo-sharing platform Instagram on Friday.

There were also more than 800 reported issues with Facebook's messaging platform.

Downdetector only tracks outages by collating status reports from a series of sources, including user-submitted errors on its platform.

The outage might have affected a larger number of users.

The outage on Monday was the largest Downdetector had ever recorded and blocked access to apps for billions of users of Facebook, Instagram and WhatsApp.
