@sailorgirl; thanks for sharing your research. Boris Johnson appears to have used an average fully vaccinated figure of 70% and 90% at least one jab of the UK's population as his trigger point.
If only our incredibly lazy, stupid and grossly incompetent PM had done the only two things he had to throughout this pandemic, heh?
With just 15% of Australians fully vaccinated, 35% having had at least one jab and the A-Z jab he bet the house on rolling around in the gutter due to poor messaging by Hymn, all we can do is battle on until at least the end of 2021. As for the people of Greater Sydney, all they can do is huddle indoors to keep safe and dream nice things about Morrison and Berejiklian.
