Is NSW going to run out of people to vaccinate?

The rules for fully vaccinated people in NSW are changing for the better next week, with a bunch of restrictions being lifted early thanks to high vaccination rates.

But the unvaccinated will have to wait with restrictions longer, as the state aims for even higher levels of vaccination across the population.

NSW, Victoria and the ACT are showing that it's possible to get to 95 per cent 12+ vaccination, which is resulting in case numbers falling.

So on today's Coronacast, at the rate we're going, when might we run out of arms to stick needles into?
