Australia's coronavirus battle has suffered multiple blows with the NSW crisis intensifying and more restrictions imposed around the nation.
NSW reported a record 478 new local cases and seven deaths on Monday, while a 15-year-old boy with coronavirus died from meningitis.
The entire state is in lockdown.
Melbourne recorded 22 new locally acquired infections, prompting the Victorian government to reimpose a curfew and extend its lockdown for another two weeks.
Playgrounds will be closed and work permits reintroduced.
Canberra's lockdown will also be extended until at least September 2 after 19 new local cases were detected in the ACT.
Darwin and Katherine will be locked down for three days after a man who spent four days in the community while infectious tested positive.
Prime Minister Scott Morrison hit out at WA Premier Mark McGowan, who is planning to pursue a goal of zero cases even when vaccination coverage reaches 80 per cent.
"The idea that you can just let this thing rip is absurd, just as absurd as the idea you can get to COVID zero," he told 2GB radio.
"They're both extreme positions. They're both absurd."
Mr Morrison said a zero-COVID target was never Australia's strategy, with the nation in a suppression phase while vaccination rates remain low.
NSW Premier Gladys Berejiklian has conceded her state will not eradicate the virus, while her Victorian counterpart Daniel Andrews agrees.
Federal, state and territory governments have backed targets of 70 and 80 per cent to reduce the possibility of lockdowns and reopen the country.
Mr Morrison said Doherty Institute and Treasury modelling underpinning the national cabinet agreement was clear about the targets' importance.
"Once you hit those levels, it is neither in our health or economic interests to go down that path," he told the ABC.
Mr McGowan said the national cabinet agreement left the door open to targeted lockdowns when 80 per cent vaccination coverage was reached.
"We will keep that as one of our weapons in the situation we're in," he told reporters.
The institute's epidemiology director Jodie McVernon cast doubt on whether the WA goal was achievable.
"My personal view is, that's a very difficult promise to keep," she told ABC radio.
The prime minister said all governments agreed to the reopening strategy three times.
"That's the deal that all premiers and chief ministers have signed up to and made that commitment to their own citizens," Mr Morrison said.
More than half of the one million Pfizer doses Australia will receive from Poland arrived overnight, with the balance to touch down on Tuesday.
About 530,000 will be rushed to 12 Sydney hot spots for people aged 20 to 39, while the rest will be shared across the country based on population.
Australia has vaccinated 26 per cent of its population aged 16 and above, while 47.7 per cent have had a single jab.
Labor leader Anthony Albanese said the new doses amounted to one week's supply and lamented the consequences of the government's slow rollout.
