After the Thai amphur wedding, the Australian citizen, permanent resident, or eligible NZ citizen sponsors the Thai spouse for a Partner (Provisional) Visa subclass 309 — granted offshore in Thailand and lasting until the permanent subclass 100 is decided. The 2-stage process gives temporary residence on grant of the 309 and permanent residence 2 years later under the 100, with full work and Medicare rights from arrival in Australia.
The Australian Embassy Bangkok issues the CNI under the Marriage (Overseas) Act 1955. The document costs AUD 161 (paid in Thai baht at the consular exchange rate on the day) and is issued at the Consular Section, 181 Wireless Road, Pathum Wan. Appointments are booked through the DFAT consular appointment system and slots are released two weeks ahead. The CNI is signed by the consular officer in front of the applicant and issued in 20–30 minutes.
Importantly, the Australian CNI is valid for only 3 months from the date of issue — couples must complete the amphur registration within this window. NYC schedules MFA legalisation, translator booking, and amphur appointment as a single workflow to ensure the CNI is used well within validity.
The CNI is bilingual (English + a French Hague heading) but Thai amphurs still require a separate sworn Thai translation legalised by the MFA Department of Consular Affairs at Chaeng Wattana. Thailand's accession to the Hague Apostille Convention (in force 14 December 2024) means the Apostille on the CNI's translation is now sufficient — the older multi-stamp consular legalisation route has been retired.
The Partner Visa is filed as a single application covering both the 309 and 100 subclasses. The Department of Home Affairs charges a base fee of AUD 9,365 (2026 indexation) for the primary applicant, with additional charges for accompanying dependent children. The visa is filed online via ImmiAccount; the Thai applicant must be outside Australia when the 309 is granted.
Stage 1 — the subclass 309 (Provisional) — is decided in 6–14 months for a complete, well-evidenced application. Evidence must demonstrate that the couple are in a genuine, ongoing, and exclusive spousal relationship under four headings: (a) Financial — joint accounts, joint property, shared liabilities, joint insurance; (b) Nature of the household — cohabitation, shared chores, joint utilities; (c) Social — joint travel, joint social media, photos with family and friends across the relationship timeline, statutory declarations from at least two Form 888 witnesses (one of whom must be an Australian citizen or permanent resident); (d) Nature of the commitment — knowledge of each other's personal circumstances, future plans, and joint long-term goals.
Stage 2 — the subclass 100 (Permanent) — is automatically considered approximately 2 years after the 309 was lodged. No additional government fee is payable. The Department reviews updated evidence of the ongoing relationship and grants permanent residence in 3–9 months. Once the 100 is granted, the Thai spouse can apply for Australian citizenship by conferral after 4 years of total residence including 12 months as a PR.
The Australian sponsor must be 18+, an Australian citizen, permanent resident, or eligible NZ citizen, and must sign a Sponsorship Undertaking pledging to provide adequate accommodation and financial support for the Thai spouse for two years from the 309 grant. Sponsors with a history of family violence or serious criminal offences may be barred from sponsoring — a National Police Check is mandatory and Home Affairs may also access the Australian Federal Police database directly.
The Thai spouse undergoes a health examination (501, 502, 707) at a Bupa Medical Visa Services panel clinic — in Thailand the approved providers are Bangkok Hospital Medical Centre, Phyathai 2, and Bumrungrad International. The examination includes chest X-ray, blood test (HIV, Hep B/C, syphilis), and general medical. A police clearance from Royal Thai Police (Special Branch, Chaeng Wattana) is also required, plus from any country the spouse has lived in for 12+ months in the last 10 years.
If the application is refused, the Thai spouse has 28 days from notification to lodge a review at the Administrative Appeals Tribunal (AAT, renamed Administrative Review Tribunal from October 2024). AAT review fees are AUD 3,374 (refunded if successful) and the tribunal typically schedules a hearing 12–24 months after lodgement. NYC works with Migration Agents Registration Authority (MARA)-registered agents in Sydney and Melbourne for AAT representation.
Couples often book the Embassy CNI early then delay the amphur wedding. If the CNI expires, the amphur will refuse the registration and the Australian must re-attend the Embassy and pay AUD 161 again.
The single most common reason for 309 refusal is thin evidence under the four headings. Photos alone are not enough — Home Affairs case officers expect joint financial documents spanning at least the last 12 months.
Statutory declarations from acquaintances who only met the couple once are routinely discounted. NYC counsels clients to nominate witnesses who have known both spouses for at least 12 months and have observed them together regularly.
Couple had lived together in Bangkok for 3 years. NYC compiled 142 pages of evidence including joint Bangkok Bank statements, joint condo lease, joint AIA insurance, and 8 Form 888 statutory declarations. No interview was requested.
Age-gap concerns were pre-empted by submitting detailed evidence of how the couple met (mutual friend introduction, 4 years of LINE chat history exported chronologically), shared interests, and family endorsement letters from the sponsor's adult children in Australia.
1) Affirmation of Freedom to Marry (single-status affidavit) issued by Australian Embassy Bangkok (CNI / Statutory Declaration); 2) Passport + valid Thai entry stamp / visa; 3) Sworn Thai translation of the affidavit; 4) MFA Department of Consular Affairs legalization of the Thai translation; 5) Thai ID + house registration for the Thai spouse. NYC handles every step under one fixed-price package.
Standard turnaround is 5–10 business days end-to-end (embassy appointment → translation → MFA → district office). Express service in 3 business days is available for an additional THB 3,500.
Any amphur in Thailand can register the marriage. NYC recommends Bang Rak, Watthana, or Pathum Wan in Bangkok — staff are experienced with foreign documents, speak English, and offer same-day appointments. Outside Bangkok, Chiang Mai, Phuket, Pattaya, and Koh Samui are also straightforward.
Yes. Australia is a Hague Apostille member, so the Thai marriage certificate (Kor.Ror.2 / Kor.Ror.3) can be translated into your home language and apostilled by the Thai MFA. The apostilled document is then directly valid back home — no embassy step required.
Most amphurs in Bangkok and tourist provinces have English-speaking officers, but Thai law requires that both parties fully understand what they are signing. NYC provides a court-approved interpreter (English or your native language) at the district office for THB 2,500.
Our all-in package for Australia nationals starts at THB 8,500 and covers embassy escort, sworn translation, MFA legalization, and amphur booking. Embassy fees (charged directly by Australian Embassy Bangkok (CNI / Statutory Declaration)) and any post-marriage apostille for home-country use are additional.
Yes. Once the Kor.Ror.3 is issued by the Thai amphur and apostilled by the Thai MFA, the marriage is recognised under section 88D of the Marriage Act 1961 in all Australian states and territories. No further registration is required, although the couple may file a Notice of Overseas Marriage with the relevant state Births, Deaths and Marriages registry if they wish to obtain an Australian extract.
Government fees: AUD 9,365 base charge + AUD 4,685 second instalment if the applicant is over 18 and fails the English language requirement (uncommon). Medical: approximately AUD 450 at a Bupa panel clinic in Bangkok. Police checks: THB 200–500. Translation and apostille of supporting documents: THB 8,000–15,000 via NYC. Total typical out-of-pocket: AUD 10,500–11,500 plus NYC service fee.
Yes. The subclass 309 grants full work rights, study rights, and immediate Medicare enrolment on arrival in Australia. The provisional status converts to permanent under the subclass 100 approximately 2 years after the 309 was lodged, with no additional government fee.
Either is accepted. Subclass 309/100 is for married couples; subclass 820/801 (onshore) and 309/100 (offshore) are also available for de facto partners who can prove 12 months of cohabitation. NYC always recommends formal marriage at the Thai amphur because the evidentiary burden is significantly lower and the visa grant rate is higher.
After your Thai marriage registration, the Kor.Ror.2/3 certificate must still pass MFA Apostille before Australia will recognise your marital status for a spouse visa.
