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
Initially registering a birth is done by a hospital through a "Birth Registration Statement" or similar, signed by appropriately licensed and authorized health professionals, and provided to the state or territory registry. Home births are permitted, but a statement is required from a registered midwife, doctor or 2 other witnesses other than the parent(s). Unplanned births require in some states that the baby be taken to a hospital within 24 hours. Once registered, a separate application (sometimes it can be done along with the Birth Registration Statement) can be made for a birth certificate, generally at a cost. The person(s) named or the parent(s) can apply for a certificate at any time. Generally, there is no restriction on re-applying for a certificate at a later date, so it could be possible to legally hold multiple original copies.
