McNair and Child Support Registrar (Child support)

This matter concerned an appeal by McNair against a decision of the Child Support Registrar. The dispute centred on the percentage of care arrangements for the parties' child, with the Registrar having revoked existing percentage of care determinations and made new ones.

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 determinations and the making of new ones under the relevant provisions of the *Child Support (Registration and Collection) Act 1988*.

The court affirmed the decision under review, finding that the evidence supported the Registrar's conclusion that a change to the likely pattern of care had occurred. The court applied the principles governing the assessment of percentage of care, considering the factual circumstances presented and the legislative framework for child support assessments.
