Caps on international arrivals will also be removed in the state.
My Ayres said the decision to remove quarantine is a natural step in re-opening the state.
“I think this is a really natural step for NSW,” he told Weekend Today, adding NSW will hit a target of 90 per cent double dose vaccination coverage in early November.
“If we’re not removing quarantine when you have 90 per cent of the population fully vaccinated I’m not sure when you’re ever remove quarantine.
“We think this is in line with the national plan and it’s appropriate and measured.”
Mr Ayres said Mr Morrison is in full support of the re-opening plan after Weekend Today host Richard Wilkins said the announcement “seemed clunky”.
“The Prime Minister made that very clear in his own press conference.
“He welcomed the announcement from NSW to remove quarantine. That is in line with the national plan.
“NSW fully recognises and accepts that the Australian government will be determining who they let into the country.”
Mr Ayres said home quarantine requirements were scrapped because it proved “too hard” to monitor on a large scale.
He explained current trials of hotel quarantine made use of a digital app with facial recognition and location-based services.
Mr Ayres said the scheme may be brought in to monitor small populations within the state.
“We may use (home quarantine) into the future if we have to do any localised lockdowns,” he said.
“Or how we might have to monitor unvaccinated people.
“(But) the idea we may have hundreds of thousands of people doing home quarantine being monitored by an application is not going to work.”
