I emailed 'justice.qld.gov.au' about the registration code - all that they could tell me was that the birth was re-registered in 1926. They could release no more information because of their access policy, which states that I would need written authorisation from herself (died in 1930), parents (probably both dec'd),children (none), siblings (none), grandparents (dec'd), grandchildren (none), spouse (none), or wait until 100 years has passed.
Does anyone know if the 100 years would be from her original birth in 1913 or the reregistration in 1926? They didn't answer that query either.
