I have previously seen a government page that listed the various terms that "kindy" and the "foundation" year of school was called in the various states. I cannot seem to find it at the moment but found a wiki page. However I was sure there were more different terms than is listed on the wiki page.
It says that the year before school (which I would term "kindy") is called "pre-school" in ACT, NT, and NSW, or "kindergarten" in SA, WA, Vic, and Tas, and "pre-prep" or "kindergarten" in Qld. (I was under the understanding that it was officially "pre-prep" in Qld, but people generally said either "kindy" or "pre-school" because that was what it had been historically.)
And it states that the first formal year of schooling (in primary school, prior to year one) is called "kindergarten" in ACT and NSW, "transition" in NT, "reception" in SA, "pre-primary" in WA, and "preparatory" in Qld, Tas, and Vic. I have heard that there are moves to rename the year nationwide to "foundation" which would at least be consistent, but seems to me like a horrible term without a logical abbreviation.
