I'm Australian, living in Japan with a Japanese wife. My son was born in Japan, and his birth and name currently are registered here only.
We didn't register a middle name in Japan, but planned to do so for his Australian documents. Sadly it seems I didn't do sufficient research at the time, as I've heard from the Embassy that they are only able to register his name for Australian citizenship as it appears on his Japanese documents (sans middle name).
I searched and found some Americans have posted about the Affidavit of Newborn Child's Name, which lets you register a name you want to use for US documents, and am wondering if there is a similar step I can take with the Australian Embassy.
Are there any Aussies who have been through the same process and had some luck?
