(a) Estimated Eligible Population is calculated using ABS citizen population figures for 30 June 2021 (revised) and 30 June 2022 (preliminary) based on the 2021 Census. ABS data is adjusted by the AEC and projected forward to the relevant date, then adjusted for British Subjects, those of unsound mind, overseas electors and new citizens since the Census.

(b) Enrolment rates above 99.0% are not reported due to error associated with calculating Estimated Eligible Population which may overstate the actual enrolment rate.
