Yuck, child support. My least favourite part of family law. I don't know why single parents get suckered into paying anything outside of what's assessed by the child support agency, but that's not my business.
CSA might take into account your school fees, but it might require a few objections and a review by the AAT to get it properly assessed, since it's unlikely she'll agree to having your contribution to school fees taken into account.
On the other stuff, lucky for you that CSA is who her complaint is with, not you. You don't even need to speak with her about the payment of child support if you don't want. That's what CSA's job is, so if she has beef about how much is being paid and how much she thinks she's entitled to, she needs to take it up with CSA, not you.
Unfortunately for her, the CSA will go by whatever your taxable income was at the end of the last financial year, and it's unlikely to change it again until your tax return is filed for this financial year.
Also, the child support assessment doesn't take into account any expenses in either household. It goes by taxable income and percentage of care.
