New South Wales (NSW) reported its biggest daily rise of 633 new cases, including 545 in Sydney, eclipsing the state's previous daily high of 478 hit on Monday (August 16). Sixty people have died since the first Delta case was reported in Sydney on June 16, including three confirmed on Wednesday.
"What the data is telling us in the last few days, is that we haven't seen the worst of it. And the way that we stop this is by everybody staying at home," NSW Premier Gladys Berejiklian told reporters in Sydney, the state capital.
Australia is in the grip of a third wave of infections that has exposed weaknesses in the country's vaccine rollout and forced more than half of its 25 million people into lockdown.
