I haven't worried about the "feeding thing" much myself when choosing schools for my kids. For me it's more about getting the match right... right kinder/school for each child at the right time.

For example, my 1st child was highly social... so I sent her to a full time 4yo kinder. Mon-Fri 9-3pm. This also allowed me to study and work. That kinder fed into her school (a girls' school) so that was that.

My second child was more sensitive and shy... he only just coped with the 8 hours per week offered by the local council run kinder. I wasn't working/studying so that suited us both.

My third child looks like missing out on kinder altogether! He is already 4 and as we have just moved he has missed out on all the council places AND private options. No matter... he'll go to a few occasional care centres and is meeting heaps of new kids at the schools my older kids are going to anyhow. I'm thinking of starting a French playgroup here too.

And don't worry about secondary school. Lord knows what they'll need when they are in highschool! When my eldest was 4yo I would have NEVER expected that she'd end up in boarding school!!! But in the end that was what was best for her.

The most important thing is matching the child to the school with the right culture and philosophy. Waiting lists can be problematic... but if you don't have to worry about that then don't stress. DH and I have moved house to be close to the best zoned school too... I know that's not for everyone but it's also an option.
