Like the OP, we have started putting away for education for our children. We are also presently looking at education funds (accounts especially geared for education) as they represent a tax break but we aren't decided on it yet.
I admit I am mildly amused at the importance placed on what job you end up with at the end of schooling. This has absolutely no significance to me having known plenty of people who've attended private schools and have worked in jobs that would be considered by some of you in here as low brow but they are well rounded individuals who speak fondly of their time in school and the friendships they made.
This is what is important to me: that my child is safe at school, makes good friends and is surrounded by an ethos that is nurturing and supported by a spiritual base. However, what our child receives at home is just as important. Having a school that assists us with this is another consideration we have.
We have costed primary and secondary schooling for one child at far less than what is being bandied about on this thread, though. Much less. And that includes inflation. We have actually looked at a few schools and have spoken to them about future attendance (even though our son is a toddler) which apparently isn't unusual.
I think that rather than go on other people's experiences, one should contact various schools in the area, speak to people, find out about future education costs etc and make your decision based on what you find as well as what your priorities are for your children. Bottom line is, I don't want my children suffering in life through want of a proper education - have met plenty of people in that boat too and it's a miserable life. No thanks. I'd rather work 50 jobs if it means getting the best shot I can give to my kids to be able to get ahead. Around here and with the interferences currently going on in our public education with the appalling NAPLAN system and other junk brought over from America, my husband and I feel we won't find that shot at a public school.
