Coronavirus: New South Wales records 110 new cases, 43 were infectious in community

New South Wales has recorded 110 new cases of COVID-19, with 43 believed to have been infectious while in the community. 

That's up from 78 cases announced on Tuesday, of which 21 were infectious while in the community. It means NSW has now recorded 1528 local cases since June 16, when the outbreak began in Bondi.

Of the local cases, 54 are linked to known cases or clusters - with 40 being household contacts and 14 being close contacts - while the source of infection for 56 are under investigation.

While 37 cases were in isolation while infectious, 43 were infectious in the community and 17 cases were in isolation for just part of their infectious period. The isolation status of a further 13 are under investigation.

There are currently 106 COVID-19 cases in hospital, with 23 people in intensive care, 11 of whom require ventilation.

A record 84,000 people came forward to be tested over the last 24 hours, described as a "great result" by Premier Gladys Berejiklian.

Berejiklian said the 43 cases "haven't necessarily done the wrong thing".

"But what it does show is how infectious and contagious the virus is so it means that every time you have contact with another human being you risk either getting the virus or passing the virus on. The simple message is please do not leave your home unless you have to."

On top of the lockdown currently in place in Greater Sydney, NSW Health announced on Tuesday night that it was imposing stay-at-home orders on three regional areas after a case was found in the region of Blayney.

The Premier said if a lockdown hadn't been imposed in Sydney, Wednesday's case total would be in the thousands.

"Had we not gone into the lockdown a few weeks ago, the 110 number today would undoubtedly have been thousands and thousands," she said. "There is no doubt about that. So we've been extremely successful in limiting the spread to what we have today."

Meanwhile, Victoria reported 22 new COVID-19 cases, all linked to known outbreaks, taking the state's total active cases to 107. Queensland hasn't recorded any new local cases.

New Zealand paused its quarantine-free travel bubble with South Australia on Tuesday night after that state went into lockdown. That pause, as well as the pause with Victoria and NSW, will be reviewed on July 27.
