As with most private schools, they would have many staff and students travelling there from out of area. Independent private schools dont have catchment areas like public or catholic/community schhols do. I didnt go to school in my LGA, at least 80% of my year lived outside the LGA the school was in, many girls travelling over an hour each way each day.
Gladys actually said on radio earlier this week that you can access the extra Pfizer at Qudos and Olympic Park if you are outside rhe 12 LGAs, especially in neighbouring LGAs, if appointments are available. Its not being promoted heavily but is possible, plus GPs have had discretion for ages. The Polish Pfizer doses have only a short period to be used (a few weeks) as reason it was being sold was because was nearing expiry date.
Whilst there are special pop up sites in LGAs of concern and priority invites/days for workers in those areas including for teachers there for the last month or so, that doesnt preclude other parts of Sydney from being at risk and acessing available doses.
I know kids in Year 12 outside the 12 LGAs who have already had first Pfizer, their parents wanted them fulky vaccinated before HSC as there are kids in the year from the LGAs of concern, as well as staff. Only approx 65% of eligible Year 12 from the LGAs of concern got Pfizered during the week where they had exclusive access at Qudos, so there are many spare doses.
Other private schools vaccinated students(not just yr 12s) back in early June when Pfizer was in low supply and no outbreak. That was queue jumping, but given extra supply and higher availability of Pfizer now in August, not really a drama that some teachers outside the LGAs got a few doses, better than having them expire.
