When an Australian document needs to be used officially in another country, the receiving authority has no way of knowing whether the document, or the signature and seal it carries, is genuine. Two linked processes exist to solve this problem: notarisation and authentication. For documents destined for China, the authentication step is now performed by Australia’s Department of Foreign Affairs and Trade (DFAT) through the issue of an apostille. Understanding what each step does, and why the process changed significantly in late 2023, helps explain what can otherwise seem like a bewildering chain of stamps and certificates.
What is notarisation?
Notarisation is the act of a notary public — a senior legal practitioner appointed under state or territory law with authority to verify documents and witness signatures for international use. Notaries occupy a distinct role from ordinary Justices of the Peace or lawyers who witness documents for domestic purposes: their seals and signatures are recognised abroad, and they are registered with DFAT precisely so that their acts can later be authenticated.
A notary can perform several functions depending on what the document requires. They can witness a person signing a document, having first verified that person’s identity, which is common for powers of attorney, statutory declarations and affidavits. They can certify that a copy of a document — a degree certificate, a passport, a company extract — is a true copy of the original they have sighted. They can also attest to the due execution of commercial documents on behalf of companies. In each case, the notary attaches a notarial certificate bearing their signature and official seal, which becomes the foundation for everything that follows.
Notarisation matters because the subsequent authentication by DFAT does not examine the content of the document at all. DFAT only verifies the signature and seal of the notary (or, for certain public documents like birth certificates, the issuing government authority). The notarial act is therefore the point at which a qualified professional actually engages with the document itself. For private documents in particular — anything not issued directly by a government registry — notarisation is usually an unavoidable first step, because DFAT can only authenticate signatures and seals that appear on its register, and a private individual’s signature does not qualify.
What is a DFAT apostille?
An apostille is a standardised certificate issued under the Hague Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents, commonly called the Apostille Convention. Australia acceded to the Convention in 1995, and DFAT is the designated competent authority for issuing apostilles on Australian documents. The apostille itself is a numbered certificate, physically attached to the document, which confirms the authenticity of the signature, the capacity in which the signatory acted, and the identity of any seal or stamp on the document. Once an apostille is affixed, every other country that is party to the Convention must accept the document as duly authenticated, with no further involvement from embassies or consulates.
The alternative to an apostille, used for countries outside the Convention, is a slower two-stage process called legalisation: DFAT first issues an authentication certificate, and the destination country’s embassy or consulate then adds its own legalisation stamp. This consular step adds cost, time and an additional point of failure.
Why China now requires an apostille rather than legalisation
For decades, China was not a party to the Apostille Convention, so Australian documents bound for mainland China had to follow the full legalisation route: notarisation, then DFAT authentication, then legalisation at a Chinese embassy or consulate in Australia. This changed when China acceded to the Convention, with the Convention entering into force for mainland China on 7 November 2023.
Since that date, the consular legalisation step has been abolished for documents moving between Australia and mainland China. An Australian document now simply needs a DFAT apostille, after which it can be presented directly to Chinese authorities. (Hong Kong and Macau had already been covered by the Convention through earlier arrangements.) The practical effect has been substantial: the process is faster and cheaper, and the Chinese consular queue is removed entirely. The same simplification works in reverse, with Chinese documents receiving an apostille from Chinese authorities for use in Australia.
The process in practice
For a typical private document destined for China — say, a power of attorney authorising someone to handle a property transaction, or a certified copy of a university degree for a work permit application — the sequence runs as follows. The document is first taken to a notary public, who witnesses the signature or certifies the copy and attaches their notarial certificate and seal. The notarised document is then lodged with DFAT, either in person at an office in a capital city or by post, together with the prescribed fee. DFAT checks the notary’s signature and seal against its register and, if satisfied, attaches the apostille. The document is then ready for use in China.
Some documents can skip the notary. Original documents issued by Australian government bodies — birth, death and marriage certificates from a registry, ASIC company extracts, Australian Federal Police checks — already bear official signatures or seals that DFAT holds on record, so they can often be apostilled directly. Educational documents are a common exception in the other direction: because institutions’ signatories are not always registered with DFAT, degrees and transcripts frequently need notarial certification first.
Practical caveats
Two cautions are worth noting. First, an apostille authenticates a document’s execution, not its content or its sufficiency for a particular purpose. The Chinese receiving body — a court, a bureau of the Ministry of Public Security, a bank — decides whether the document itself meets its requirements, and many will insist on a certified Chinese translation, which is usually arranged in China or specified by the receiving authority. It is prudent to confirm with the end user in China exactly what form and content they expect before beginning the chain. Second, requirements can vary between Chinese provinces and agencies, and some local bodies took time to adjust to the apostille system after November 2023, so checking current acceptance practice for the specific authority involved remains wise.
Conclusion
Notarisation and the DFAT apostille perform complementary roles in a chain of trust. The notary verifies the document or signature at its source; DFAT’s apostille then certifies the notary’s authority in a form that China, as a party to the Apostille Convention since November 2023, is bound to accept. What was once a three-stage process ending at a Chinese consulate is now a two-stage one ending at DFAT, making the international use of Australian documents in China considerably simpler — provided the document is properly prepared at the notarial stage and meets the substantive requirements of the authority that will ultimately receive it.
