Medical and health document translation for Australian authorities and health providers
Short answer
Thai medical records — medical certificates, treatment histories, laboratory results, vaccination books and prescriptions — need an English translation when they are submitted to an Australian authority or health provider. Translations produced in Australia must come from a NAATI-certified translator; translations produced overseas must show the translator's full name, address, contact details and qualifications. The visa health examination itself is different: it is performed by a panel clinic and sent electronically through eMedical, not translated by the applicant. Translation normally takes 1–3 business days.
Key facts
| Receiving parties | Department of Home Affairs (health-related evidence in a visa application), Australian hospitals and treating doctors, insurers, and regulators such as AHPRA |
|---|---|
| Accepted translation format | In Australia: NAATI-certified translator. Outside Australia: the translation must state the translator's full name, address, contact details and qualifications. |
| Documents usually translated | Medical certificates, treatment summaries and discharge notes, laboratory and imaging reports, vaccination records, prescriptions, and antenatal or delivery records |
| What is not a translation job | The visa health examination is completed by a panel clinic and submitted electronically through eMedical; applicants do not translate it themselves. |
| Turnaround | Typically 1–3 business days depending on page count and scan quality |
| Delivery format | PDF with the translator's stamp and CPN number; printed copies on request |
Documents usually translated
Medical certificates
Used to confirm a condition, a rest period or fitness to travel. The translation must keep the facility name, the doctor's registration number, the issue date and the diagnostic wording exactly as written, without summarising or adding new clinical conclusions.
Treatment history and discharge summaries
Requested when treatment continues in Australia or when health circumstances are explained in a visa application. Translate every page in date order and keep diagnostic codes and drug names as they appear in the source.
Laboratory and imaging reports
Values, units and reference ranges must be copied exactly; never convert units or round numbers in the translation. Tabulated reports should be laid out so they can be read side by side with the original.
Vaccination records
Used by Australian schools, childcare providers and health services. Translate the vaccine names, the date of each dose, batch numbers and the provider, keeping both trade and generic names as recorded.
Prescriptions and regular medication lists
Allow a treating doctor in Australia to continue prescribing and support carrying medicine into the country. The translation should show generic name, strength, dosage and the prescribed duration.
Maternal and child health records
Antenatal books, delivery records and child development records are often used when registering with a health provider or school. Translate them together with the birth certificate so names and dates match across the set.
Step by step
1. Confirm what the receiver actually needs
Ask the authority or clinic whether they require a NAATI-certified translation, a translation carrying the translator's details, or also a certified copy of the original — requirements differ by receiver.
2. Scan the complete original legibly
Scan every page in colour at 300 dpi or better, including pages with stamps, handwritten notes and numbered blank pages. If handwriting is unclear, ask the facility to reissue a typed version.
3. Match name spelling to the passport
Give the English spelling of names exactly as shown in the passport so health records, identity documents and department forms all carry the same name.
4. Use a translator certified in the right direction
Thai–English work is completed by a translator certified in that language direction, with a stamp, date and CPN number that can be verified in the NAATI online directory.
5. Proofread clinical terminology against the source
Check drug names, units, result values and dates line by line against the original before the stamped PDF is delivered, and keep the original available if the authority asks to see it.
Common mistakes
- • Translating only the pages that seem relevant, leaving an incomplete set that the receiver later asks to top up
- • Converting units or rounding test values so the translation no longer matches the original
- • Summarising a doctor's diagnosis instead of translating the wording as written
- • Omitting stamps, the doctor's signature or the practitioner registration number from the translation
- • Spelling the patient's name differently from the passport so the record cannot be linked to the application
- • Assuming the visa health examination is a translation task when it must be done at a panel clinic and lodged through eMedical
- • Supplying skewed or blurred phone photos in which laboratory figures cannot be read
Frequently asked questions
Do Thai medical documents always need a NAATI translation?
It depends on where the translation is produced. Translations made in Australia must come from a NAATI-certified translator. Translations made outside Australia must display the translator's full name, address, contact details and qualifications. Because Australian hospitals and departments are most familiar with a NAATI stamp, that route usually carries the lowest risk of being asked for more documents.
Does the Australian visa health examination need to be translated?
Normally no. The visa health examination is carried out by a panel clinic appointed by the Department of Home Affairs and the results are lodged electronically through eMedical. What often does need translating is earlier treatment history, past test results or a medical certificate that the clinic or case officer asks you to attach as supporting evidence.
Should a child's vaccination book be translated before starting school in Australia?
Australian schools and childcare providers generally ask for immunisation evidence in English, so every recorded page of the vaccination book should be translated, including vaccine names, the date of each dose and the provider. An Australian health provider then decides how the history is recorded in the national immunisation register under the relevant rules.
Do I translate a whole medical file or only the relevant parts?
The safest approach is to translate the complete set you intend to submit, because selecting pages can look incomplete to the receiver. If the file is very long, ask the hospital to issue an official treatment summary first and translate that summary in full, always keeping the Thai originals attached.
Does a medical translation also need notarisation or consular legalisation?
For most submissions to Australian authorities it does not: a translation carrying a certified translator's stamp is enough. Additional certification by a notarial services attorney or by the Thai Department of Consular Affairs is usually only relevant for legal proceedings, insurance disputes, or countries that require a layered legalisation chain. Confirm with the receiver first.
What happens when the doctor's handwriting is illegible?
A translator will not guess wording. Unreadable text is marked as illegible in line with standard practice for official documents, which can prompt the receiver to request more evidence. It is better to ask the facility for a typed reissue or a computer-generated summary and translate that version instead.
How long does a medical translation take?
Ordinary jobs take about 1–3 business days from receipt of clear scans and confirmed name spellings. Files with many result tables, long treatment histories, or mixed languages in one booklet take longer. If you have a fixed lodgement date, state it when you send the files.
Health data is sensitive — how is it handled?
Send files through a controlled channel such as direct email or the provider's LINE account rather than public groups. The information is used only to produce the translation, and you can ask for the files to be deleted once the job is complete. If you need a written confidentiality undertaking, request it before work starts.
Can translated medical records be used with Medicare or an insurer?
They can be used as supporting evidence, but eligibility and claim decisions rest with the agency or insurer, which usually wants the translation, the original and its own claim form. Check the receiver's document list first, then prepare the full translated set in one go.
Which documents do Thai doctors and nurses translate for AHPRA registration?
Mostly professional rather than patient documents: the practising licence, a Certificate of Good Standing from the relevant Thai council, academic transcripts and employment references. Our Thai professional council page covers each profession, and current criteria should always be checked on the AHPRA website.

Medical documents: steps and what to prepare
Medical certificates, treatment histories, laboratory results and vaccination records are used for visas, study and continuing care abroad. Translations must preserve clinical terms and units exactly.
Step 1: Request a complete set from the hospital
Ask for records bearing the doctor's signature, licence number and hospital seal, specifying the treatment period you need.
Step 2: Confirm the level of detail required
Some destinations need a single certificate; others require the full treatment history and laboratory results.
Step 3: Translate in the accepted system
Keep drug names, dosages, units and diagnostic codes exactly as written — no interpretation or summarising.
Step 4: Submit and keep a spare set
Retain the translation files; overseas clinics frequently ask for them again during continuing treatment.
What to prepare
- Medical certificate or treatment history with the hospital seal
- Laboratory results and imaging reports where relevant
- Vaccination record or immunisation certificate
- The patient's passport, plus consent if a third party is acting
Why sets get sent back
- Handwritten notes that cannot be read should be reissued in typed form by medical records
- Documents without the doctor's licence number are often refused
- Health data is sensitive; send it through a controlled channel and state the scope of use
If you would rather not track each step yourself, send scans on LINE. Our team, which has handled this type of work for over 15 years, will map your document route first — where it should end, how many copies you need, and which steps would be wasted — and you decide afterwards whether to do it yourself or hand it to us.
Medical documents: terminology accuracy comes first
Medical records carry specialist terms and abbreviations where a wrong rendering changes the meaning. We check the legibility of the source first, and we give no medical advice beyond translation.
What we check before starting
- Whether the source is legible, especially handwriting and test results
- How recent the recipient requires the medical certificate to be
- Whether attached results and hospital seals must also be translated
- Whether the doctor's signature and registration number must appear in the translation
Where we tell you not to spend
- Many hospitals can issue an English medical certificate directly
- Requesting a clean printed original reduces the risk of later corrections
What we do not promise
- • The receiving authority decides the outcome; we do not promise results
- • Government fees and processing times vary with the period and the workload of each office
- • We do not give legal, financial or medical advice beyond the scope of translation and certification
