... primary school is not a great concern - good or bad, as long as you don't live in problematic suburbs ... there are about 450 suburbs in Melbourne and perhaps as many primary schools, so before anyone can give you advise, would you pls first pick which area you want to settle, such as north, east, etc ...
... i would suggest you to come first, and look around later on ... no need to worry about it now, there are too many suburbs and schools around Wantirna ...
