Burney and Morrison argue proposed $300 payment to get vaccinated

But, Prime Minister Minister Scott Morrison rubbished the idea, saying, "Australians want to [get vaccinated] because they know it's good for them, it's good for their families...and I'm backing them in".

Federal government data has revealed Sydney' Inner South West, which includes St George and Canterbury Bankstown, has the second lowest vaccination rate in Sydney.

Only about a third of people over the age of 15 have had a first dose and 16 per cent have had both.

Labor leader Anthony Albanese announced the $6 billion policy to give $300 to everyone who was fully vaccinated by December 1.

Ms Burney said the proposed policy would assist vaccine take-up and stimulate the St George economy.

"This support would be a further incentive for St George to be fully vaccinated and would deliver a much-needed shot in the arm for businesses, workers and families struggling from lockdowns," she said.

Mr Morrison said the idea was a "vote of no confidence" in Australians.

"It says to them that any health concerns that they have about a vaccine can be paid off," he said. "And doing it for the cash, I do not think is what would motivate an Australian."

Mr Morrison said Australia had a very good record of high immunisation rates.
