OP not sure where you are but although most kinders "feed" into a primary school locally the choice is totally yours as to where they go. Our kinder feeds to a local school but we will be sending our kids to another PS nearby not the closest one to our kinder. As for high schools in Melbourne, nearly all are zoned now, so you basically take the Melways and then find a ruler and the closest high school boundary to boundary to where you live. You can apply to schools outside of your area but you have to have pretty strong reasons as to why they need to go there usually based on things like academics, or languages offered etc. There is a site called better education that also ranks schools based on their VCE results that is handy to use in conjunction with Myschools and then I would say to tour the schools when you get a bit closer to deciding. Good luck - it's so full on choosing what to do!
