"If she were permitted to live in Australia, I find that [Mr D] would assume the role of [the child's] father and that, within a short time, [the child's] relationship with her father would be of little value. In my judgment the mother's attitude towards the father combined with the limited direct contact would not permit a relationship between the father and [the child] to be sustained. To lose the significant relationship which she has with her father would not, as I find, be in [the child's] present or future interests and would be inimical to her welfare."
