Hi again Amanda,
We have already emailed each other, but I thought I'd post for the benefit of anyone else who wanted to know.
As an international student who is bringing school age children you have to have them enrolled into school and send a confirmation of enrolment with your student visa application.
You pay $3600 per child anually for Dependent Tuition fees, and they can go to any state school, subject to zoning restrictions (the same as everyone else).
I had to pay 6 months up front to get my visa.
