I think that was announced by I guess the NSW authorities maybe about a week ago.Woolworths just started that there're advocating all staff to get vaccinated, setting up a hub in Sydney LGA areas of distress.
Also giving all staff upto 8 hours paid leave to get the jab.
It's this type of movement & positivity from large corps that will get the critical %% heading north.
The workers in the big 5 supermarkets (Woolworths, Coles, Aldi, IGA and ???) in the 8 LGAs are in the priority queue (I'm guessing with the pregnant women that was also announced recently - I'm thinking/feeling just afterwards).
