As  this is a  general post and not a specific question in our QNA or #Discussion area I will respond generally. 

The child can not be forced against their will to do anything.

Last year a mother came to me as their daughter (14) wanted to live about 150 kilometres away with friends. She called the police ... nothing they could do to help. She called DOCS/FACS ... nothing they could do to stop her from going.

Now that matter did not involve the Family Court, however the Family Court also can not force a teenager to do anything against their will and you as a parent would urgently need to apply to the court for a variation to the orders due to a “significant change of circumstances” so the Court is aware there is a problem with compliance that is out of your control.
