The research revealed that 29 per cent of people will say no to the jab while only 14 per cent declared they were extremely likely to be vaccinated.
Vaccine doubts were stronger now than before reports the AstraZeneca vaccine was linked to blood clots.
The public hesitancy about vaccine could prove disastrous for the Prime Minister Scott Morrison’s plans to reopen Australia’s interstate borders and kickstart international travel.
“Those public health orders are the instrument that is used legally to prevent Australians moving from one state to another,” Mr Morrison said.
A year since the pandemic hit, Mr Morrison said his strategy to reopen international borders “is one step at a time and a risk that Australia can manage safely”, indicating he was open to quarantine at home but “it’s not something that’s doable yet”.
Mr Morrison described the reopening as “a gradual process”.
Phases would include Australians moving more freely around Australia, possibly under vaccination passports, then Australians being able to travel overseas if they have been vaccinated and potentially quarantine at home.
Mr Morrison said about the same time, Australians who had received “approved” vaccinations overseas could return safely.
Meanwhile, the NSW Government is considering opening a second mass vaccination hub, possibly near Newcastle.
The first clinic at Sydney Olympic Park has been deemed a major success by health officials.
