No idea really. With Kinder (here in Vic), the one DD1 went to there was a voluntary fee of $90 up front or $25 a term (was never made clear it was voluntary), also heaps of fundraising (unfair as other kinders it was one or the other). Also I did not agree with all the expenditure.

At primary school, I am not even sure our fee was voluntary I know other schools locally paid for a book list, but we had one fee which covered books and also things like swimming lessons at the end of the year. Just looking up what the go is with school fees here.
