A business innovation application is unlike most visa applications in one respect: the bulk of the evidence is not about you, it is about a company. And company records behave differently from personal ones. A birth certificate comes from a registry that will reissue it. A shareholders' register comes from a corporate filing system in another jurisdiction, and proving to an Australian decision-maker that the extract is genuine is a chain of steps done there, not here.
That is the single distinction that decides most of what follows.
Overseas corporate records. Certificates of incorporation, company extracts, shareholder and director registers, share certificates, and constitutional documents. If the company is registered overseas, these are commonly notarised and legalised in the country of incorporation. An Australian notary cannot attest that a foreign corporate registry issued a document — no notary anywhere can vouch for a register they have no access to. Confirm the exact form with the nominating state or territory and against current guidance.
Audited financial statements and accountants' reports. Where these come from an overseas firm, the usual pattern is that the accountant signs a declaration before a notary in that country, and the statements are bound in as an exhibit.
Asset and business valuations. Property valuations, plant and equipment reports, and independent business valuations prepared overseas typically follow the same route: the valuer attends a notary locally, the report is annexed.
Ownership and source-of-funds evidence. Where funds or shareholdings sit in another country, the bank or registry confirmation is usually notarised and legalised there.
A power of attorney, in your favour or someone else's. Business applicants are frequently in Australia while a co-director or accountant assembles records offshore. A notarised and apostilled power of attorney is often what makes that possible.
For documents lodged with the Department of Home Affairs, a certified copy by an authorised person is usually sufficient, and the range of people who may certify is wide. Paying notarial rates for these is a common and avoidable expense:
Ask what standard of copy is wanted before booking anything. "Certified" from an Australian agency and "certified" from an overseas authority rarely mean the same thing.
Once a business is operating here, the traffic often reverses. Australian documents needed by an overseas authority — an ASIC extract, an Australian company constitution, a director's declaration, evidence of an Australian business for a home-country currency-control approval — are notarised in Australia and then either apostilled by DFAT, where the destination is a party to the Hague Apostille Convention, or DFAT-authenticated and then legalised at that country's embassy or consulate where it is not.
This is the part of a business migration file that an Australian notary can actually do, and it is often the part left until last.
Company filings in another language need an English translation. For Australian immigration purposes, translations prepared in Australia should be by a NAATI-credentialled translator; translations prepared overseas should show the translator's full name, address and credentials.
A notary does not translate. A notary can attest the translator's declaration and bind the translation to the source document — which is what overseas registries and some assessing bodies expect.
For an overseas corporate document:
For an Australian document heading overseas:
Corporate chains run longer than personal ones, because a registry extract has to be recent enough for the recipient and each step consumes that freshness.
If an extract must be "issued within three months", work out step 1's date from the lodgement date backwards.
Can an Australian notary certify my overseas company's registration? Not as a genuine corporate record. A notary can certify that a copy matches a document produced to them, but that is a much weaker statement than the authentication chain in the country of incorporation, and it is usually not what is being asked for.
My accountant is overseas. Can they sign and email the declaration? A notarial act requires the signatory to attend in person before the notary. The accountant attends a notary where they are; the notarised document travels.
Do audited accounts need an apostille as well as notarisation? It depends entirely on who is receiving them. Confirm with the nominating authority or the receiving body — do not pay for a step nobody asked for.
