Returning to Cambodia on a Different Passport: The Aussie 2026 Guide
Renewed your Australian passport? Married and on a new surname? Travelling on a second passport for business? Cambodia treats every fresh passport number as a fresh applicant — here's what changes, what stays the same, and what biometrics still catch.
I'm an Aussie returning to Cambodia on a different passport — what do I need to know about the eVisa?
Each Cambodia eVisa application is keyed to the passport number, not your underlying identity. A renewed Australian passport, a second passport for business travel, or a passport in a new married surname produces a fresh application with no carry-over from prior trips — same $80 USD (~$122 AUD) Tourist or $90 USD (~$137 AUD) Business fee, approved in 3 business days, delivered as a printable PDF by email. Cambodia's MFAIC has no visibility on your prior visa history under the old passport number, so you apply as a 'new' applicant. The one place identity does resurface is at Immigration biometrics on entry — face match and fingerprint can still tie you back to a prior Cambodia record, which only matters if your earlier history included an overstay, deportation, or fraud flag.

- Cambodian Immigration keys to passport number, not person identity. A renewed, replaced, or post-name-change passport produces a fresh eVisa record with no link to prior trips on the previous passport number.
- Your prior visa history isn't visible to MFAIC under the new passport — you apply as a 'new' applicant with $80 USD (~$122 AUD) Tourist or $90 USD (~$137 AUD) Business, approved in 3 business days.
- Name-change marriage, DFAT renewal, second passport for business, and emergency replacement all produce the same application shape — what differs is the supporting paperwork you may need to carry on the plane.
- Biometrics on entry (face match, fingerprint) can still surface a prior Cambodia record even when the passport number is new — relevant only if your earlier history included an overstay, deportation, or fraud flag.
- The fix for a passport number mismatch on an existing eVisa is a free resubmission with the new details — never travel on a PDF that shows the old number.
Why Cambodia treats a new passport as a new applicant
The four Aussie scenarios — different passport, different paperwork
Scenario 1: DFAT-renewed passport (same name)
Scenario 2: post-marriage name change
Scenario 3: second passport for business travel
Scenario 4: emergency replacement passport
What the fresh application actually looks like under a new passport
The biometrics caveat — what new-passport identity does NOT reset
Don't try to use a new passport to dodge a prior overstay
Aussies sometimes ask the desk whether a renewed passport can be used to 'reset' a prior unpaid overstay. The honest answer is no — biometrics catch the link at entry, and arriving with an unresolved overstay on the record is a worse outcome than clearing it upfront. The clean path is to pay the overstay at exit before you return on the new passport, or to clear it through the Cambodian embassy in Canberra before the next trip if you've already departed.
اکثر پوچھے گئے سوالات
I just renewed my Australian passport — does my old Cambodia visa history carry over?
No. Cambodia keys every eVisa record to the passport number, so your renewed passport produces a fresh applicant record with no link to prior trips on the old number. Apply on the new passport — $80 USD (~$122 AUD) Tourist or $90 USD (~$137 AUD) Business, approved in 3 business days, delivered as a printable PDF by email. The cancelled stamps on the old passport are not operationally relevant at KTI, SAI, or KOS.
Do I need to mention previous Cambodia visits when applying on a new passport?
No. The eVisa form has no field for prior Cambodia history under a different passport number and does not require you to declare it. Type the new passport details exactly as they appear in the machine-readable zone, apply, and treat the application as you would a first-time application. Cambodian MFAIC has no system view of the prior record under the old number.
I got married and my passport is in a new surname — what does the eVisa application look like?
A fresh application on the new passport, using the name exactly as it appears on the new passport's machine-readable zone. Same $80 USD (~$122 AUD) Tourist or $90 USD (~$137 AUD) Business fee, 3 business days, printable PDF by email. Carry the marriage certificate and a statutory declaration of name change in your carry-on for airline check-in scenarios where booking details still reference the maiden name.
I travel on a second Australian passport for business — does Cambodia accept it?
Yes. DFAT-issued second passports are valid Australian travel documents and Cambodia processes them like any other Australian passport. The eVisa is keyed to the second-passport number; carry the DFAT authorisation letter that links the two passports in case an airline flags the second-passport boarding pass. The Cambodia eVisa second passport guide for Australians has the full mechanics.
Can my biometrics still tie my new passport back to my old Cambodia visits?
Yes — Cambodian Immigration runs face-match and fingerprint biometrics on air arrivals at KTI, SAI, and KOS. The system can link your new-passport entry back to a prior visit on the old passport. For travellers with clean prior history, this surfaces nothing the officer cares about. For travellers with a prior unpaid overstay, deportation, or fraud flag, the biometric link is the moment Immigration brings it up — clear the prior issue before returning.
