it depends which state you live kindy/pre-school are all different but for us been in melb the cut off date is April so if your child turns 4 before april 30th then he or she can go to kindy or you have the choice if your child is young to hold back, so I had a April baby he didnt go to kindy until he was 4 turning 5, all children born after the 30th of April have to be 4 turning 5

most other states the cut of is end of june so all kids will be 3 turning 4 for the 1st half of the year or 4 turning 5 for the 2nd half of the year

does any of that make sence?
