You haven't asked a question, so I'm going to assume you're asking if the father's assertions are correct.
Parenting orders remain in place until the child turns 18, and unless by agreement or reasonable excuse, deviations from the order are contraventions, regardless of the child's age.
However, rather than make a contravention order, the court may choose instead to amend the existing orders based on what's best for the child. Generally speaking, children of around 12 years of age are ordinarily deemed old enough and informed enough for their wishes about their care arrangements to be given weight by the court, and I assume this is what the father is banking on to justify his actions.
Before orders are formally amended by the court, however, this is an incorrect interpretation, and the existing orders remain standing until formally changed, or the child turns 18.
