How many actually have a Birth Certificate they can produce as this is now a mandated requirement under the new rules? A full certificate, not an extract.
Your passport is no longer sufficient.
Wait, you say. I had to produce my BC to get my passport. No matter says Canberra...we know better than to rely on that!
So add another $100 or so to the next renewal and take your passport as your documentary proof of ID to the BDM Registry.
