'Highly unlikely' NSW lockdown will end as planned
NSW on Sunday recorded its highest daily total of infections in the current outbreak, with 77 new local COVID-19 cases in the 24 hours to 8pm on Saturday.
Of the 77 new cases, only 32 were in isolation for all of their infectious period.
The premier expects this toll will be surpasses on Monday when health authorities report infection numbers for the 24 hours to 8pm on Sunday.
"I'll be shocked if it's less than 100," Ms Berejiklian told reporters on Sunday.
It was "highly unlikely" lockdown provisions in Greater Sydney and surrounds will be lifted as scheduled on Friday, which will mark the end of a third week of stay at home orders.
There are 15 Covid-19 patients in NSW in intensive care, with five on ventilators.
Federal Chief Medical Officer Paul Kelly said one of the six SummitCare Baulkham Hills aged care residents who caught Covid-19 from an infected staff member was "seriously unwell" in hospital.
That person was the only infected resident who was unvaccinated.
