Aussies on their second, third or fifth Cambodia application often ask whether the system remembers them. The short answer: it remembers some things, it ignores others, and a handful of events do follow you. Here's the honest picture.
Yes, but selectively. Prior approvals make nothing easier or faster — each Cambodia eVisa application is a fresh case, processed in the same 3 business days at $80 USD all-in (~$122 AUD) Tourist or $90 USD (~$137 AUD) Business, delivered as a printable PDF by email. A prior rejection does not ban you and you can re-apply the same day once the flagged field is corrected. Prior overstays do attach to your file and trigger manual review, with possible fines on next entry. A prior 'wrong purpose declared' record — for example a tourist caught doing paid work — sits on the file permanently and is the single most damaging item. An old overstay from years ago is usually recoverable with honest disclosure.
Australian travellers on their second or third Cambodia application often arrive at the form with the same low-grade anxiety. Does the system remember me? Did that 2019 rejection follow me into 2026? What about the four extra days I overstayed in 2017? The honest answer is that Cambodian Immigration does keep records, but the records are narrower and more practical than most Aussies fear. Some events are essentially forgotten. Others sit on the file for life.
This piece walks through the four scenarios our returning-traveller desk handles most often: a prior approval, a prior rejection, a prior overstay, and a prior 'wrong purpose declared' record. For each one, we describe what is actually on the file, what it does to your next application, and what you can do about it. The goal is to replace anxiety with a clean factual picture, so you can decide whether to apply as Tourist, switch to Business, or in a small number of cases route through the embassy instead.
Cambodia runs a single integrated record per passport number. Every eVisa application you have submitted, every entry and exit logged at KTI, SAI, KOS or one of the open land borders, every extension lodged in-country, and every fine or breach noted by an immigration officer sits on the same file. The record is keyed to the passport number, not your name, so a passport renewal does carry the history across — DFAT issues your new passport with a different number, but the Cambodian system links the two during your first eVisa application against the new passport.
The Cambodia eVisa application form does not show you any of this history. There is no "your past applications" page. You can apply with the same email twice and see no continuity between the sessions. The history exists, but it only surfaces when Cambodian Immigration looks at a flagged case — typically because something in the new application contradicts the older record. The Cambodia Tourist visa for Australians guide and the Business visa for Australians guide both apply the same rules to repeat applicants.
This is the most common scenario and also the most over-thought. You applied for a Cambodia eVisa in 2023, were approved, used it, flew home, and now in 2026 you are looking at applying again. The short truth: nothing about your prior approval changes the new application. The form is the same, the price is the same, the 3-business-day window is the same, the document requirements are the same.
The one genuine returning-traveller advantage is that you already know which fields trip people up. Passport expiry inside the 6-month window. The accommodation field needs to match what you put on the e-Arrival Card later. The photo specs are unforgiving on heavy side-shadow. By application three or four, most Aussies fill the form in 15 minutes instead of 35. That is the only meaningful upside, and it lives in your head, not in the system.
If you want a refresher on what each field expects in 2026, the documents-required guide for Australians covers every input on the form. The Friday-application timing guide covers the question of when in the week to submit if you want the 3-business-day window to land sensibly across an Aussie weekend.
A Cambodia eVisa rejection feels heavier than it is. It is not a ban. It does not blacklist you from Cambodia. It does not even prevent you from applying again the same day. Most rejections are technical — a photo that did not pass the face-match algorithm, a passport scan with a fingertip on the bottom of the data page, an accommodation field with a misspelled hotel name, a passport expiring inside the 6-month window. Cambodian Immigration sends a short rejection notice naming the flagged field, and you re-apply with the correction.
What does sit on the file after a rejection: the fact of the rejection, the flagged field, and the timestamp. A single rejection is almost invisible to the next application — the system treats it as a standard cleanup. A pattern of repeated rejections against the same passport (four or five in a short window) can trigger a manual look, particularly if the flagged fields look like an attempt to game the system rather than a genuine fix. That is rare. Most Australian rejection cases are one-and-done.
Overstays are the one category where the record actively matters. Cambodian Immigration logs an overstay against your passport number with the number of days, the airport or land border you were caught at, and any fine paid. Overstay fines are $10 USD (~$15 AUD) per day from day 31 onwards, capped at $300 USD (~$457 AUD) before deportation procedures kick in. The fine is usually paid at the desk on exit. The flag stays on your file regardless of whether the fine was paid.
On your next eVisa application, the system pulls the overstay flag and pushes the case into a manual review queue. Manual review extends processing past the standard 3 business days — typically to 5 to 8 business days — and triggers a closer read of the new application. In most cases the new eVisa is still approved, particularly if the overstay was minor, the fine was paid on exit, and the new application is straightforward. In a small number of cases — typically longer overstays without fine payment, or repeat overstays — the new eVisa can be refused.
Most Aussies who overstayed by a couple of days years ago, paid the fine on exit, and have not been back since are not facing a real problem. The flag is on your file, but the system reads it as a minor closed event. A new Cambodia eVisa application in 2026 against the same passport will likely route through manual review, take 5 to 8 business days instead of 3, and be approved. The two things that change the picture: declare honestly on the application if there is a free-text field (there usually is not), and consider applying for the Business eVisa instead of the Tourist if the original overstay involved a long stay — the Business class signals you understand the longer-stay path now.
The embassy route for cases involving any kind of historic immigration friction is covered in the Cambodian embassy in Canberra guide for Australians. The Tourist-versus-Business decision after an overstay sits inside the broader visa-type comparison guide.
The single most damaging item that can sit on a Cambodia immigration file is a 'wrong purpose declared' flag. The classic case: an Australian enters on a Tourist eVisa and is later found running paid work — teaching English, freelancing for a Cambodian client, taking sales meetings, doing supplier visits, due-diligence trips, attending conferences as a speaker, or working at a sponsored event. Tourist is the wrong product for any of those, and if Cambodian Immigration logs the breach the flag is permanent.
The practical effect on future applications: every subsequent eVisa for that passport routes through manual review. Tourist applications carry a higher risk of refusal — the system reads them as a repeat of the original misdeclaration. Business applications usually still go through, on the basis that the applicant is now applying for the correct class. The processing window stretches to 5 to 10 business days in these cases. The flag does not have a published expiry — once it is on the file, it stays.
The cleanest answer if you suspect this flag is on your file: apply for the Business eVisa at $90 USD all-in (~$137 AUD) from your next trip onwards, and never apply for the Tourist eVisa again. The Business class is designed for meetings, paid work, conferences, sales calls, supplier visits, due-diligence and sponsored events, and is the correct product for any traveller whose Cambodia activity touches paid work in any form. Switching products signals to Immigration that the original miscategorisation has been corrected.
For most Australians, the eVisa history conversation is shorter than it feels. If your record is clean — prior approvals only, no overstays, no breaches — nothing on the file changes anything about your next application. Apply fresh, allow 3 business days, fly. If your record has a single old overstay that was settled at exit, your next application will probably route through a slightly longer review window and then go through. If your record has a 'wrong purpose declared' flag, the answer is to switch to Business eVisa from now on.
The two genuine returning-traveller advantages — faster form-filling and a clearer sense of which Cambodia airport (KTI, SAI, KOS) makes sense for your itinerary — are covered in the Cambodia airports guide for Australians and the country pillar at do Australians need Cambodia visa.
