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.
Bank fraud
Identity theft has become an increasing problem; the scam operates by obtaining information about an individual, then using the information to apply for identity cards, accounts and credit in that person's name. Often little more than name, parents' name, date and place of birth are sufficient to obtain a birth certificate; each document obtained then is used as identification in order to obtain more identity documents. Government-issued standard identification numbers such as "social security numbers" are also valuable to the fraudster.
