Is it legal for the non main carer to take your own child out of the country on holiday?
Under Australian the non main carer can take a child out of the
Country on Holidays.
The child must have a passport. To obtain a passport, both
parents need to sign the application form. If the other parent will
not consent to the application for a passport then an application
to the court must be made.
If the child has a passport, then the holiday can be taken
provided that it is in accordance with the Orders of the court, or
by agreement with the other parent.
If you are worried about the other parent taking the child out
of the country without your agreement, then you can apply to the
court for the child to be put on the airport watchlist.
