NSW records 478 new cases and 7 deaths

NSW recorded 478 new locally acquired COVID-19 cases and seven deaths in the 24 hours to 8:00pm yesterday and hit a grim new record, passing Saturday's previous high of 466. A 15-year-old Sydney boy who was being treated for pneumococcal meningitis as well as COVID-19 has died.

Ms Berejiklian has said today's 478 cases was a number that was "disturbingly high".

NSW Health said 61 cases were infectious in the community, 30 were in isolation for part of their infectious period and the isolation status of 290 remain under investigation

Yesterdays 7 deaths was the highest number ever recorded in the state within a 24-hour period.

"Unfortunately, only two of them had one dose of a vaccine and all the others were unvaccinated," the Premier said, adding the death of a 15-year-old we''ve previously reported on was not included in that grim tally.

"Tragically, since that time, we also had that eighth death of the very young teenager."

The news comes as tightened lockdown rules come into force across much of Greater Sydney in a fresh attempt to slow the spread of the Delta variant.

From now, residents cannot go further than five kilometres from their home unless it is for one of the "reasonable excuses" listed by the NSW Government.

Police have launched Operation Stay at Home this morning, with hundreds of additional officers to be out ensuring people are complying with public health orders.

A further 500 Australian Defence Force troops, in addition to the 300 already deployed, will assist with compliance checks and patrols, particularly within hotspot suburbs.

One million additional Pfizer doses are imported from Poland overnight. Half of those will be rolled out to Sydney's 12 local government areas which have the highest rates of the virus from today.

The remaining doses will be given to other states and territories on a per capita basis.

The state's largest mass vaccination hub also opens today, based at the Qudos Bank Arena at Sydney Olympic Park.
