Families in Australia take many and varied forms, including blended families, sole parent families, families headed by same sex couples, and with children conceived from donor sperm. In this article the author asks how the law is responding to accommodate diversity in relationships and family structure. She provides an overview of social trends and an historical background in relationship diversity, and examines the current status of family law with regard to marriage, children residence and contact, financial support of children, adoption, and property redistribution.
