Greater Sydney and surrounding regions are in lockdown until at least August 28, as health authorities battle to contain an outbreak of the virulent Delta strain.
"Again, workplaces and households are the main places where the virus is transmitting so we urge everybody, if you must leave the house, assume everybody that you're coming into contact with has the virus," Premier Gladys Berejiklian said on Tuesday.
The premier urged those who live in communities adjoining eight local government areas under stricter lockdown conditions not to enter those areas.
Ms Berejiklian said she wants the state to get to six million vaccinations by the end of August. Some 3.9 million doses have already been provided.
Meanwhile, a major Sydney hospital and two nursing homes are dealing with Covid-19 outbreaks as health care workers come under stress while the Delta strain of the virus continues to surge.
Thirty-six staff at Westmead Hospital are reportedly in isolation after a vaccinated colleague who worked three shifts last week while infectious tested positive.
There are now 232 Covid-19 patients in Sydney hospitals.
It comes as the number of Covid-19 cases at Wyoming Nursing Home in Summer Hill rose to 18 residents and two staff members.
Another contract staffer at another nursing home, St Hedwig Village at Blacktown, has also reportedly tested positive for the virus but no other cases have been identified so far.
All residents on one floor at the Wyoming Nursing Home have been taken to hospital as a precaution.
The Greater Sydney, Blue Mountains, Central Coast, Wollongong and Shellharbour area regions have been in lockdown since late June.
Queensland has recorded 16 new locally-acquired cases of Covid-19, with all linked to existing cases but some infectious in the community for up to six days.
The 16 new cases recorded on Tuesday are all linked to the west Brisbane Delta outbreak taking that cluster to 47.
Chief Health Officer Jeannette Young says the 34,718 tests conducted overnight is encouraging for ending a hard lockdown of the state's southeast on Sunday, but she has urged people to stay home.
"Please don't move the virus," she told reporters on Tuesday.
"So wherever you are in those 11 LGAs if you can at all, just stay put so that that virus then doesn't move, because we know that there are people out there who could have been infected, who have no symptoms."
"So the best way to deal with someone who has no symptoms is that they just stay at home. That's why lockdowns work, because we know that the virus can burn out. So please just stay at home."
One new case is linked to Indooroopilly High School, four cases are linked to Brisbane Grammar School, two are linked to Brisbane Girls Grammar, three are linked to Ironside State School, five are household or family contacts of existing cases, and one is a neighbour of an existing case.
Dr Young said the original family of five who became infected are closely linked to two overseas-acquired cases who were being treated in hospitals on the Sunshine Coast.
Some of the new cases have been infectious in the community for up to six days and 7995 people are in home or hotel quarantine.
There are 400 frontline health workers in isolation, including all cardiac surgeons at the Queensland Children's Hospital.
Some surgeries and outpatient services will be delayed, the chief health officer said, because of staff shortages at hospitals.
"No Queenslander will be denied any care because the health workers they need are in quarantine, we'll work through that, but we do have a large proportion of our critical health workers now in quarantine," Dr Young said.
Most of the quarantined health workers have been vaccinated, she said, but there's a risk of them passing on the virus to their patients.
Deputy Police Commissioner Steve Gollschewski said 70 infringement notices had been issued and 21 people arrested with only a small proportion of those related to an anti-lockdown protest in Brisbane's CBD on Monday.
"This is the real community safety issue, people die from this virus, they get terribly ill, and even worse with this particular variant we're seeing our young people get ill, which is just unforgivable if we spread it," Mr Gollschewski said.
Health Minister Yvette D'Ath said nine of the 16 new cases are children and one is the neighbour of a known case, so people should think seriously about leaving home.
"Please think about your reasons why you're leaving your home, is it truly essential," she said.
