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.
Birth certificate
Birth registration opens the door to rights to children and adults which many other human beings take for granted: to prove their age; to prove their nationality; to receive healthcare; to go to school; to take exams; to be adopted; to protection from under-age military service or conscription; to marry; to open a bank account; to hold a driving licence; to obtain a passport; to inherit money or property; and to vote or stand for elected office.
