The Cambodian eVisa portal technically accepts a DFAT Emergency Passport, but acceptance at Cambodian Immigration is inconsistent in 2026. Here is the honest read of when to risk it, the safer fall-back via Visa on Arrival at KTI, SAI or KOS, and the cleaner path of replacing with a full passport before the trip.

Technically yes — the Cambodian eVisa portal accepts the passport number on a DFAT Emergency Passport the same as any other Australian passport, and the application will process. The practical answer is more cautious. Acceptance of Emergency Passports at the Cambodian arrival counter is inconsistent in 2026, with some officers stamping through without comment and others citing the 'not for general travel' wording on the document to reroute the holder to Visa on Arrival instead. If you can replace the Emergency Passport with a full DFAT 10-year passport before the Cambodia trip, that is the cleaner path. If not, plan to apply for a Visa on Arrival at KTI, SAI or KOS with the Emergency Passport as proof of identity, rather than relying on an eVisa-and-arrival match.
A DFAT Emergency Passport is not a routine document. Australian embassies and consulates issue them to citizens in genuinely distressed situations overseas — a passport lost or stolen during a trip, a damaged document that cannot be repaired in time, an in-country emergency that requires immediate travel, or a stranded citizen who needs to get home but cannot wait the standard renewal cycle. The Emergency Passport is a red-cover document, intentionally distinctive, and typically issued with 12-month validity to limit its use to the immediate crisis.
The question of using one for a Cambodia eVisa comes up most often in two scenarios. The first is the Aussie traveller mid-trip in another country who had their primary passport stolen, has been issued an Emergency Passport by the local Australian embassy, and now has a Cambodia leg booked for next week that they want to keep. The second is the traveller who had to fly home on an Emergency Passport after an overseas incident and is now planning a Cambodia trip while still inside the 12-month Emergency Passport window. Both scenarios have the same core question: will the Emergency Passport actually get me through Cambodian Immigration?
The Cambodian eVisa portal treats every passport number as a unique identifier. It does not differentiate between a standard 10-year DFAT passport, a 5-year child passport, a DFAT second passport, or a DFAT Emergency Passport at the application step. You submit the passport number, the bio scan, the photo, and the application processes against that number. Approved eVisas are issued on Emergency Passports regularly, and the PDF that lands in the applicant's inbox looks identical to any other approved eVisa. So far, so smooth.
The arrival counter is where the story changes. Cambodian Immigration officers do recognise the red cover of an Emergency Passport on sight — the colour is the most obvious visual cue. When the cover registers as Emergency Passport, the officer's response varies materially by airport, by shift, and by individual judgement. Some officers stamp through without comment, treating the eVisa as the binding document and the Emergency Passport as a valid identity carrier. Others pause, flip to the back of the document where the 'not for general travel' phrasing typically appears, and route the holder to secondary review.

If your Cambodia trip is more than 4 weeks away and you can practically replace the Emergency Passport with a full DFAT 10-year passport in the meantime, that is the cleaner path. The Emergency Passport is, by design, a stop-gap. DFAT expects the holder to replace it with a standard passport at the earliest reasonable opportunity, and the standard replacement runs on the normal renewal channels.
A new passport means a new application
The Cambodia eVisa is tied to the passport number on the application. If you had an eVisa issued against the Emergency Passport and have now replaced with a standard passport, the old eVisa is unusable at the border. Apply for a fresh eVisa against the new standard passport number before the trip.

If the trip cannot wait, the Emergency Passport is in your hand, and the standard or priority renewal does not fit the timeline, the honest answer is to plan for the worst case at Cambodian Immigration rather than hope for the best. The most practical approach is to skip the eVisa entirely and arrange a Visa on Arrival (VoA) at KTI, SAI or KOS using the Emergency Passport purely as proof of identity.
The other practical detail is the e-Arrival Card. Every air arrival into Cambodia must submit the 14-field e-Arrival Card within the 7-day window before flight, regardless of whether the visa is an eVisa or a VoA. Submit the e-Arrival Card under the Emergency Passport number. The card costs $5 USD (~$7.50 AUD), takes about 15 minutes to complete, and is independent of the visa-type decision.
Don't try the eVisa-and-also-have-VoA-ready combination
If you apply for the eVisa on the Emergency Passport and also plan to do VoA at the airport, Cambodian Immigration will see the active eVisa in the system and may insist on processing entry against that. The two paths are not interchangeable at the counter. Pick one — VoA-only is the cleaner Emergency Passport path.

In-country crisis with no other passport available. If you are currently overseas, your primary passport has been stolen, the local Australian embassy has issued you an Emergency Passport, and you have a Cambodia leg booked for next week that you cannot reschedule — the practical answer is to fly to Cambodia and present the Emergency Passport for Visa on Arrival at KTI, SAI or KOS. Carry the police report from the loss/theft as supporting documentation in case the officer asks. The Cambodia visa lost passport emergency guide has the wider playbook for this scenario.
Damaged Emergency Passport. If the Emergency Passport itself is damaged in any way — water damage, torn pages, a damaged photo, a broken laminate, or material wear on the bio page — do not attempt the Cambodia entry. Return to the nearest Australian embassy and arrange a replacement. A visibly damaged Emergency Passport is the worst combination at the Cambodian arrival counter and almost guarantees a refused entry.
