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.
Identity document
The card must be renewed every ten years and is freely issued again if lost. Among the information included there are, on the front, two identification pictures and digitized signature of the owner, identification number (known colloquially just as the "cédula"), first name, first and second-last names and an optional "known as" field. On the back, there is again the identification number, birth date, where the citizen issues its vote for national elections or referendums, birthplace, gender, date when it must be renewed and a matrix code that includes all this information and even a digitized fingerprint of the thumb and index finger.
