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 fraud
The unauthorised use of a stolen credit card is commonly not considered identity fraud, but may be considered consumer fraud. The use of fake names, ID cards, falsified or forged documents, and lying about his or her own age to simply "hide" his or her true identity is sometimes also regarded as identity fraud. Reasons for this type of identity fraud may include wanting to purchase tobacco or alcohol as a minor as well as to continue playing on a certain sports team or organization when that person is really too old to compete. 
Identity fraud is the act of using a stolen identity to obtain goods or services by deception. This usually involves the use of stolen, forged or counterfeit documents such as a passport or driving licence. The term 'goods or services' typically includes bank accounts, mortgages, credit cards, rail products, an application for a job or simply dishonest claims for state benefits.
