Cambodia Visa for Australian Dual Citizens: 2026 Same-Passport-Rule Guide
Australian dual citizens have one rule above all others for Cambodia — pick a passport, apply on it, enter on it, exit on it. The 2026 specialist guide for AU+UK, AU+India, AU+Vietnam, AU+China, AU+NZ, and AU+Philippines duals.
Which passport should an Australian dual citizen use to enter Cambodia?
Pick ONE passport for the whole trip and stick with it. Cambodian Immigration scans the same passport at entry and at exit — switching mid-trip causes problems every single time. For most AU duals (AU+UK, AU+India, AU+Vietnam, AU+China, AU+NZ), the Australian passport is the easier choice because the eVisa for Aussies is one of the simplest in SE Asia ($80 USD / ~$122 AUD all-in Tourist, 3 business days). But if your other passport offers visa-free entry or a cheaper visa fee, that's a legitimate alternative — just apply on it, and DON'T pull out the AU passport at the border.

- Pick ONE passport for the whole Cambodia trip and stick with it — Cambodian Immigration scans the same passport at entry and at exit. Switching mid-trip causes problems every single time.
- For most Aussie duals (AU+UK, AU+India, AU+NZ, AU+China), the Australian passport is the easier path — eVisa is $80 USD (~$122 AUD) all-in Tourist, 3 business days, no flight or hotel proof required.
- AU+Vietnam duals: the Vietnamese passport CANNOT use the Cambodia eVisa portal. Vietnamese nationals need the embassy route, so use your Australian passport instead.
- The eVisa is bonded to the passport number on the application. If you enter on one passport and try to exit on the other, the airline gate spots the missing entry record and you do not board.
- Cambodia recognises dual citizenship and does not ask about your other nationalities on the application — but DFAT records your AU exit on whichever passport you departed on, which can matter on the way home.

Edge cases within the dual-citizen space
- Triple citizens (AU + UK + India is the most common combo we see): the rule does not change — pick one passport and use it for entry and exit. Most AU triples use the Australian passport for the same reasons as AU+UK and AU+India duals.
اکثر پوچھے گئے سوالات
Can I use either passport to enter Cambodia if I am a dual citizen?
Yes, but only one of them per trip. Cambodian Immigration scans the same passport at entry and at exit, and the eVisa is bonded to the passport number on the application. Pick which passport you will enter on, apply for the visa on that passport, and use it for both the entry stamp and the exit stamp. Switching mid-trip causes problems at the airline gate every single time — TIMATIC sees no matching entry record on the second passport and the boarding pass is declined.
What if I have Vietnamese AND Australian citizenship — which passport for Cambodia?
Use the Australian passport. The Vietnamese passport is not eligible for the Cambodia eVisa in 2026 — Vietnam is not on Cambodia's eVisa-eligible country list. Vietnamese nationals must apply through the Royal Embassy of Cambodia in Hanoi or Ho Chi Minh City, with physical documents and a 5-7 business day timeline. The Australian eVisa is $80 USD (~$122 AUD) all-in Tourist, 3 business days, and applies online from anywhere. AU+Vietnam duals almost always use the Australian passport for the Cambodia leg.
Do I need to declare my dual citizenship when applying for the Cambodia eVisa?
No. The Cambodia eVisa application form does not ask about second citizenships, and Cambodian Immigration does not collect that information. You declare one nationality — the one on the passport you are applying with — and the rest of your citizenship picture is not Cambodia's concern. Cambodia's constitution recognises dual nationality for its own citizens, and it does not interrogate the status of foreign duals.
What if I entered Cambodia on my UK passport but want to exit on my Australian one?
Don't. Cambodian Immigration's exit scanner will not find a matching entry record on the Australian passport, and the airline check-in counter will flag it via TIMATIC before you reach the gate. You will not board. Use the passport you entered Cambodia on for the entire Cambodia leg — including the exit stamp. If you have already entered on the UK passport, exit on it too. The Edge Cases for Australians guide covers what to do if the discrepancy has already happened.
Can my child travel on a different passport than mine?
Yes — Cambodia treats each passport as a separate visa application, and there is no requirement for family members to all use the same nationality. Each child needs their own Cambodia eVisa under their own passport, with their own photo and their own fee. That said, if it is practical, having all family members on passports of the same nationality (typically Australian) for the same trip simplifies the AU departure and re-entry side and keeps the family record consistent.
