In our area (Maroondah) you have already missed the deadline for enrolments for kinder in 2013. So you may want to at least contact the kinders as soon as you can to keep your options open. - oops, just realised that you won't be wanting it for another year anyway.
I think the main point of 3yo kinder is a very gentle introduction to education - a few hours a week, lots of playing with other kids, and as much parental involvement as is needed.
