Thubron and Thubron (Child support)

This matter concerned an appeal by the father, Mr Thubron, against a decision of the Child Support Registrar to revoke existing percentage of care determinations and make new determinations. The dispute centred on whether there had been a change to the likely pattern of care for the subject child.

The primary legal issue before the court was whether the Registrar had erred in revoking the existing percentage of care determinations and making new ones, specifically whether the Registrar had correctly applied the provisions of the *Child Support (Registration and Collection) Act 1988* (Cth) concerning changes to the likely pattern of care.

The court affirmed the Registrar's decision, finding that the evidence supported a conclusion that there had been a significant and likely permanent change in the pattern of care for the child. The court considered the relevant legislative framework and the factual circumstances presented, concluding that the Registrar had acted within their powers and had made correct determinations based on the evidence before them.
