A birth certificate is unusual among the documents people bring to a notary. It is issued by a government registry, which means it is itself a public document — and an original Australian birth certificate can, in many cases, be taken to DFAT and authenticated without a notary being involved at all.
So the first decision is not how to get a certified copy. It is whether you need one, or whether the original should go overseas instead. The answer turns on one question: do you need to keep the certificate?
Route A — the original, authenticated directly. You send the registry-issued certificate itself to DFAT, which checks the registrar's signature and issues an apostille or authentication. The original, with the apostille attached, goes overseas. You will probably not see it again.
Route B — a notarised copy. A notary sights the original and certifies a copy as true and complete. DFAT then authenticates the notary's signature and seal, not the registrar's. The copy goes overseas; the original stays with you.
Both are legitimate. They are not interchangeable, and choosing the wrong one is a common reason for a set being returned.
One caveat: DFAT can only authenticate a signature it can verify. Very old certificates, or ones signed by a registrar whose signature DFAT does not hold, may not be accepted directly. A newly issued certificate avoids the problem.
Australian registries have issued birth certificates in different formats over the years and across jurisdictions. Some older or shorter formats omit details — parents' names, place of birth in full — that a foreign authority may expect to see. A certified copy reproduces exactly what the original shows, and nothing it does not.
Before booking, compare your certificate with the recipient's requirements. If it lacks something they need, a full certificate from the registry is the fix; no notarial wording can add information that is not on the original. (Commemorative certificates, which DFAT will legalise but many overseas authorities do not want, are covered on the separate page on notarising a birth certificate.)
The notary sights the original registry-issued certificate — not a photocopy, scan, or a copy certified earlier by someone else — and certifies that the attached copy is true and complete.
The notary is not confirming the facts of the birth, your parentage, or that the certificate was lawfully issued. Only the registry stands behind those.
Can I do both — apostille the original and keep a notarised copy? Yes. Have the certified copies made first, then send the original for direct authentication. The copies can be apostilled separately if they need to be.
Does the apostille on a notarised copy mean my birth certificate is verified? No. It verifies the notary's signature and seal. An apostille on the original verifies the registrar's signature. Some recipients care about the difference — another reason to ask which they want.
My certificate has an old surname. Add a statutory declaration linking the names, notarised at the same time. This is covered in more detail on the birth certificate how-to page.
How many certified copies should I get? One per recipient, plus a spare, bearing in mind that each may need its own apostille.
