Gladys Berejiklian isn't wavering in her determination to get as many people in NSW vaccinated against COVID-19 as soon as possible, saying the AstraZeneca jab is safe and "absolutely critical" in the fight against the pandemic.
Numerous countries have suspended their AstraZeneca vaccine rollout after some recipients developed blood clots, but the premier is not deterred.
"The best health advice we're getting in Australia is that it's absolutely safe," she told reporters on Tuesday.
"I have full confidence in the vaccine and I have full confidence in our health experts. I certainly wouldn't have taken it if I hadn't done my homework - which I have - and I feel completely safe."
Within three weeks NSW will have completed an extra 80,000 jabs and 45,000 new people would have started their vaccine process.
NSW has recorded no new cases in the community since a security guard, who worked at a Sydney quarantine hotel, was diagnosed with the virus on the weekend.
NSW health authorities were on high alert after the 47-year-old guard was diagnosed after the state had 55-day COVID-free hiatus.
It isn't clear how the guard at Sydney's Sofitel hotel contracted the virus as there were no obvious breaches of health protocols, but he has the same highly-contagious UK strain as an infected returned traveller on the floor he was working.
It is hoped that the guard was less contagious after receiving the first shot of the Pfizer vaccine but investigations are still under way to determine the source of his infection, NSW Health's Dr Jeremy McAnulty said.
"Testing continues on close contacts of the case, who remains asymptomatic. The case's household contacts have all tested negative and will continue to self-isolate for 14 days," he said.
Health alerts remain in place for venues around Hurstville, in Sydney's south, where the guard had visited.
The guard's infection sparked concern other states were poised to shut their borders again.
"There is no reason now for anywhere in Australia to have internal borders," Ms Berejiklian said.
"While the vaccine is being rolled out and the level of transmission is low-to-negligible there shouldn't be any internal borders in our nation. We should be moving freely as Australians."
If just one state closes its border "everybody loses confidence because people don't want to move around if they think they're not going to be able to get back home".
With Easter less than three weeks away people needed certainty in order to make travel plans, the premier said.
NSW vaccinated frontline workers first because they posed the greatest risk of the virus seeping into the community from hotel quarantine.
"Given we've managed that risk, given that other states are managing that risk there's absolutely no reason for borders to close," Ms Berejiklian said.
"This is a good opportunity for our nation to have a reset - for our nation's leaders and say let's keep our borders open in the interests of our citizens."
