The average australian is increasingly accepting that when we get to a point where all those who can/will are vaccinated then the validity of lockdowns become increasingly questionable.
The average australian is also increasingly accepting that at some stage we have to live with this and accept a level of sickness, hospitalisation, ICU and death; being vaccinated will lessen the effects of Covid, Covid cannot be eliminated.
The timeline is nominally end of this year, the Feds will make it clear - they already are - there will be no hope for financial assistance to lockdown states after this time; there'll probably be assistance/infrastructure grants available for states who won't lockdown.
I would hope and expect there will always be assistance at the ground level for any states that require it.
ScoMo will run a February campaign on the basis of as far as possible everything being open by Easter school holidays.
Labor will have trouble balancing their support for Comrade Dictators Vs the peoples reasonable expectations that "we're vaccinated, lets go": ScoMo will win (whether you think he should or not's irrelevant).
The average australian may wear lockdowns for now, once all are vaccinated they won't because common sense says it's no longer a valid (or as valid) approach.
