DD is in 4 yr old this year but did 3 yr old last year!
we love kinder she did 2x2hr sessions last year and it cost around $250 a term (one session a week was $125 a term)
we chose it because we did toddler group the year before, love the staff etc..
id apply to both, check them both out then make a decision on which you prefer
we have to apply early, as in as soon as the applications come out due to its popularity (if thats a concern though,join the committee) our wil be out asap for next year, offers are made around august,
our council you apply directly to the kinder but most around us you have to apply to the actual council

goodluck!
