Cambodian visa on arrival needs a passport-size photo at the booth. Forgot to bring one? The on-the-spot photo machine costs $2 USD (~$3 AUD) and is sometimes broken. Here's the honest spec, the airport-by-airport fallback, and why two spare photos from Australia is the safer plan.

The Cambodia visa-on-arrival booth requires one passport-size photo at the desk — 35x45mm equivalent, plain white background, recent (within 6 months), with the face fully visible and unsmiling. The spec is identical to the Cambodia eVisa photo. If you forget to bring one, the booth runs an on-the-spot photo machine for around $2 USD (~$3 AUD), payable in USD cash. The machine is sometimes broken, queue is its own queue, and a resubmission for a dark or blurry photo costs another $2 USD (~$3 AUD). There is no realistic print or photo option at KTI, SAI or KOS before the VoA desk — the booth machine is the only on-arrival fix. The safer plan for Aussies is to take two passport-size photos at a chemist in Australia before flying (~$15-20 AUD for a set of four) and carry them with your USD cash. The eVisa avoids the on-arrival photo exercise entirely.
Of every Australian arrival we have walked through the Cambodian VoA booth in the last twelve months, the missing photo is the second-most-common reason they get sent back from the counter — behind only damaged USD cash. The rule is genuinely simple: one passport-size photo at the booth, plain white background, recent. The problem is that most Aussies assume the booth will take a digital photo on the day, or that the photo at the back of their passport will somehow count, or that the photo they took on a phone a year ago can be printed somewhere inside the terminal.
None of those assumptions work in 2026. The booth officer needs a physical 35x45mm-equivalent print, attached to your application form, recent enough that you still look like the photo. The on-the-spot photo machine exists, but it costs $2 USD (~$3 AUD) per attempt, charges in USD cash, has its own queue, and has been out of service on at least one of our last six visits across the three airports. This guide walks through the spec, the on-arrival fallback, and the safer plan of carrying two spares from Australia.
The Cambodian Immigration photo standard for VoA in 2026 matches the eVisa specification almost exactly — the only practical difference is that VoA needs a physical print at the booth, while the eVisa accepts a digital upload. The spec itself has not changed materially since 2023, but enforcement has tightened: officers are now actively rejecting photos that would have been waved through a few years ago.

Every Cambodian VoA booth has access to an on-arrival photo machine — a self-service box installed somewhere near the booth, usually a few metres to the side. The machine takes a photo, prints a strip of two passport-size shots, and the booth accepts those prints on the application form. The cost is around $2 USD (~$3 AUD) per use, paid in USD cash into the machine's coin/note slot. The booth does not handle the payment; the machine does.

Se você precisa de um Cartão e-Arrival do Camboja (e um eVisa do Camboja) durante uma escala no Aeroporto Internacional Techo (KTI) ou Siem Reap (SAI) depende de uma pergunta: você vai cruzar a linha de imigração? Aqui está o regulamento exato de 2026 para transferências airside, passagens separadas e voos domésticos.
As regras de fronteira do Camboja mudaram significativamente para 2026: Phnom Penh abriu o Aeroporto Internacional Techo (KTI), selos de papel foram substituídos pelo V-Pass digital, e todas as passagens terrestres entre Tailândia e Camboja permanecem fechadas. Aqui está a lista de verificação completa de entrada de 2026 para viajantes canadenses.
Cidadãos britânicos que viajam para o Camboja em 2026 precisam tanto de um visto cambojano válido quanto de um Cartão e-Arrival digital do Camboja (CeA). Aqui está como os portadores de passaporte do Reino Unido escolhem entre o eVisa de Turista (Classe T), eVisa Ordinário (Classe E) e Visto na Chegada no Aeroporto Techo (KTI) ou Siem Reap (SAI).
The booth officer can refuse the machine print if the lighting was uneven or the result is blurry. In that case you go back to the machine, pay another $2 USD (~$3 AUD), retake the shot, and rejoin the booth queue. The first attempt does not count as a refund — each attempt is a fresh transaction. If the machine is out of service, the booth has no alternative provision; you wait until it is fixed (which can be hours) or you walk back through security to the public side of the terminal to find a manned photo shop.

Taking two passport-size photos before flying is the single cleanest way to remove the booth-photo risk. The job takes ten minutes at any Australian chemist or Australia Post outlet, costs around $15-20 AUD for a set of four prints, and produces the right size, background, and quality on the first try. Carry the photos in a small envelope inside your hand luggage alongside your USD cash — the same envelope, in fact, makes the booth visit calmer.
Two physical prints is the right number. One for the booth application, one as a spare in case the officer rejects the first for any reason. Keep them flat in an envelope rather than folded in a wallet — bent corners or creases get rejected at the booth.

A handful of Australian arrival scenarios push the photo rule into edge-case territory. None are deal-breakers, but knowing the rule in advance avoids a queue reset at the booth.
Every Australian child needs their own VoA photo, including infants. The chemist photo service at home accommodates this — the technician will support the child's head against a plain background and take a single neutral-expression shot. The booth machine is harder for small children because the camera is fixed at adult height. Photos taken in Australia are strongly recommended for families with kids under 5.
Cambodian Immigration removed the glasses exemption in 2023. All photos must be taken without glasses, even prescription. If you took the photo at home with glasses on, take it again. If the booth machine is your only option, remove the glasses before pressing the button.
If you have already used VoA on a previous trip and arrive again within six months, the same photo can be reused as long as it still meets the recency rule. If you are unsure whether the photo is still acceptable, bring a fresh one — the officer's call on recency is final.

Run this checklist a week before flying and the booth photo step becomes a non-event. None of the steps takes more than ten minutes.
