Today, the Prime Minster issued a desperate message on radio.

"We've just got to get this lockdown right, Sydney, we've gotta get it right," Scott Morrison said on Nova FM.

But Labor says the Prime Minister is the one who got it wrong - criticising Mr Morrison for praising the NSW Premier for not rushing to lock down as well as for the delays to the vaccine rollout.

"Scott Morrison bears significant responsibility for this third wave," Shadow Health Minister Mark Butler said.

However, Mr Morrison insists the vaccine rollout is back on track.

"We'll have another record day today," he said on Nova, claiming "over 15 million doses would've been delivered."

"One in four Australians are now fully vaccinated," Mr Morrison added.

The Government expects every Australian who wants a jab will have one by October.
