All the information you will need on what avenues are available to you will be listed, i.e. starting with the Family Relationship Centres and then if that fails, in the Grandparents area click on the "Family Law for Grandparents" link.
The link to the Law and Justice Foundation website will explain how to go about applying to the Federal Magistrates Court.
It is important to remember that the court views access to grandparents from the child/children's perspective, i.e. that they have a right to an ongoing relationship with their grandparents and extended family members, rather than the other way round.
