A wide range of state and federal laws recognise and regulate intimate and familial relationships. Such laws include inheritance, immigration, guardianship and superannuation as well as the areas that we traditionally think of as ‘family law’: property division and disputes over children following relationship breakdown.
There is no reliable demographic data on how many adults identify as lesbian or gay in Australia, but there is information to indicate that many lesbians and gay men live in long-term relationships, some of which include children. The Australian census has never asked individuals to identify their sexuality, but in 1996 and 2001 invited people to record if they are living in a same-sex relationship. These figures underestimate the numbers of couples for a variety of reasons: in 1996 the question itself was confusingly worded, and many people were unaware that they were able to record their relationship for the first time. The census does not record couples who do not cohabit. In addition, there are still many same-sex couples who would not feel comfortable recording their relationship on an official document such as a census.
