Document Legalisation for Australians Moving to Thailand

Thai government agencies — Immigration, the Department of Employment, Land Departments, and courts — only accept foreign documents that have been officially authenticated. An Australian document (birth certificate, marriage certificate, police check, degree) presented in its original form without authentication will be rejected. The internationally recognised method is the Apostille, issued under the Hague Convention, to which both Australia and Thailand are signatories.

The Department of Foreign Affairs and Trade (DFAT) is the competent authority in Australia for issuing apostilles. Process: 1. Obtain the original document from the issuing authority (Births Deaths and Marriages registry, AFP for police checks, university for degrees, etc.). 2. Lodge for apostille with DFAT — online via dfat.gov.au or in person at DFAT offices in Canberra, Sydney, Melbourne, Brisbane, Adelaide, or Perth. Processing time: typically 3–10 business days for online lodgement. Fee: AUD 105 per document (2025 rate — verify at dfat.gov.au). 3. DFAT attaches the apostille certificate to the document.

After apostille, most Thai agencies require a certified Thai translation of the document. Translations must be by a qualified Thai translator (in Australia, this means a translator accredited by NAATI for Thai). Visa Centre works with NAATI-accredited Thai translators in Australia to provide this service.

For certain document types — particularly those used in Thai court proceedings or land transactions — the Thai Embassy in Canberra or the Royal Thai Consulates-General may additionally certify the apostilled, translated document. This is a separate step to the DFAT apostille. Visa Centre advises on a case-by-case basis whether this additional step is required for your specific purpose.

Australian Federal Police (AFP) check — required for Non-O-A retirement visa, Non-B business visa, and most Thai immigration applications. Birth certificate — required for marriage registration, name change applications, and children's applications. Marriage certificate — required for Non-O (marriage) visa, property transactions, and name changes. Degree and professional qualification certificates — required for work permit applications and certain BOI applications. Power of attorney documents — for property purchase or sale when the Australian party is not present in Thailand.

Allow 4–6 weeks minimum for the full document chain: AFP check processing (up to 15 business days), DFAT apostille (up to 10 business days), NAATI translation (3–5 business days), Thai Embassy certification if required (5–10 business days). Visa Centre manages the sequencing and tracks each document on your behalf.
