If you are relocating to, studying in, marrying in, or doing business with Australia, your Thai Diploma will only be accepted once it carries both the Thai MFA legalization stamp and the Australia embassy authentication. We prepare the certified translation, secure the consular stamp in Chaeng Watthana, and submit the file to the Australia mission at อาคาร M-Thai สาทรใต้ on your behalf.
Why the legalization chain is required
Each layer in the legalization chain authenticates the layer beneath it. The certified translation is verified by the translator's declaration; the MFA authenticates the translator's registered signature; and the Embassy of Australia authenticates the MFA. Break the chain anywhere and the Australia authorities can lawfully refuse the Diploma, even if the underlying facts are correct.
Certified translation requirements
Most Australia authorities require the Thai Diploma to be accompanied by a certified translation into a language the mission accepts — typically English, or the official language of Australia. The translation must be faithful, complete, and produced by a translator whose signature the Thai MFA can verify. We use MFA-recognised translators so the translation itself can be legalised alongside the original.
Transparent, itemised pricing
Costs are itemised, never bundled opaquely. Expect the Australia consular fee (60-160 AUD), the MFA legalization fee (THB 200–400 standard), translation (THB 800–1,500/page), and our handling fee (สอบถามเจ้าหน้าที่). We quote the exact total up front — including courier — so there are no counter-side surprises when your Diploma reaches the Australia mission.
Realistic timelines you can plan around
The Australia mission's own processing (7-14 วัน) is the least controllable part of the timeline, which is why we start translation and MFA legalization immediately and submit to the embassy the moment the MFA stamp is dry. Total realistic turnaround for a Diploma is 7–21 business days; we give you an honest date at quotation, not an optimistic one.
What a legalised Diploma is used for
Foreign nationals typically need a legalised Diploma when dealing with Australia government offices, courts, universities, employers or banks — anywhere the receiving party must trust a Thai record. At this mission the highest-volume documents are NAATI Certified Translation, Notarized Documents, Police Clearance, and we handle each with the correct chain for its purpose.
Common mistakes we help you avoid
Rejections usually come from small, avoidable errors: an expired Diploma, a translation that omits an official annotation, a name that reads differently from the passport, or a document submitted to the Australia embassy out of sequence. We verify document freshness, translation completeness and stamp order before anything is lodged.
