Tegan, Kinder is Pre-school and visa versa. Different states have the different names for it though and different programs.

I only enrolled Lindsay at 3 for his 4 y.o year before entering school and was so lucky that we don't have the waiting lists, but know that our town has become a mining town, I enrolled Erin into a full 3y.o day because preference is given to those children who have attended as a 3y.o and the waiting lists are starting to get long too.
