Provisor and Barwick (Child support)

This matter concerned an appeal by Provisor against a decision of the Child Support Registrar concerning the percentage of care for the parties' child. Provisor sought to have the Registrar's decision, which had revoked existing percentage of care determinations and made new ones, set aside.

The primary legal issue before the court was whether there had been a change to the likely pattern of care for the child, which would justify the revocation of existing percentage of care determinations and the making of new ones under the *Child Support (Registration and Collection) Act 1988* (Cth).

The court considered the evidence presented regarding the actual care arrangements for the child and the likely future care arrangements. It applied the principles established in child support legislation and relevant case law concerning the assessment of the percentage of care, focusing on whether the evidence demonstrated a significant and ongoing change to the established pattern of care. The court affirmed the Registrar's decision, finding that the evidence supported the conclusion that a change to the likely pattern of care had occurred.
