City of Sydney Relationships Declaration
Other institutions such as the Registry of Births Deaths and Marriages no longer accepts an Australian Marriage Certificate as a form of ID – this creates an equal situation for both opposite sex and same sex couples as both are not allowed to present their relationship certificates as a form of ID.
Genealogical certificate
Genealogical certificates were issued until December 31, 2008, by the civil registry office that had certified the birth. It contained, among other things, the child's name, sex, date of birth, place of birth, and parents' names. There are also any changes listed in a genealogical certificate that have occurred since the birth of the child, such as adoption or name changes.
