Five visa classes exist on paper — but only two matter for ~99% of Australians: Tourist eVisa (T-Class, $80 USD / ~$122 AUD) and Business eVisa (E-Class / Ordinary, $90 USD / ~$137 AUD). The other three (A diplomatic, K Khmer-by-birth returnees, B official) require embassy applications and don't apply to ordinary AU travellers.

Five visa classes exist on paper — but only two matter for ~99% of Australians: Tourist eVisa (T-Class, $80 USD / ~$122 AUD all-in) and Business eVisa (E-Class / Ordinary, $90 USD / ~$137 AUD). The other three (A diplomatic, K Khmer-by-birth returnees, B official) require embassy applications and don't apply to ordinary AU travellers. Almost every Aussie reading this needs T (leisure, Angkor, family visits) or E (business meetings, paid work, long stays).
Search around for 'Cambodia visa types' and you will find lists, tables, and infographics that gleefully name five visa classes — T, E, A, K, B — as if each one is a live option an Australian traveller might pick at the application stage. They are not. Cambodia does operate a five-class visa system on paper, codified by the General Department of Immigration and used internally to categorise every foreign national entering the country. But for ordinary Aussies — leisure travellers, business travellers, digital nomads, retirees, family visitors — only two of those classes are ever issued: T and E. The other three are reserved for people whose passport, posting, or heritage already places them outside the ordinary tourist track.
This guide is the honest 2026 catalogue. We will walk through what each of the five classes is actually for, which ones an Australian can apply for through the eVisa portal, which ones live exclusively at the Royal Embassy of Cambodia in Canberra, and — most importantly — which one fits the trip you are planning. By the end you should know with certainty whether your trip is a T job or an E job. If you walk away thinking you need an A, K, or B class, you have either a very unusual situation or you have read the table wrong.
If you only need the headline answer for your specific trip, the pillar page Cambodia visa for Australian citizens has the short version, and Do Australians need a Cambodia visa is the overview eligibility piece. The two specialist guides — Tourist eVisa for Australians and Business eVisa for Australians — go deep on the T and E classes respectively. This guide is the catalogue: the full five-class system, what each one means, and where Aussies actually land.
Below is the complete catalogue of Cambodia visa classes as they stand in mid-2026, mapped to Australian relevance and where you would actually apply for each one. Two classes — T and E — are the only ones available through the online eVisa portal and the only ones an ordinary Aussie will ever lodge themselves. Three classes — A, K, and B — sit outside the portal entirely and require an embassy submission, eligibility paperwork, or in some cases an institutional sponsor. The honest answer for around 99% of Aussies is the top two rows.
The Tourist eVisa, written as Type T on the approval PDF, is the default Cambodia visa for Australian leisure travel. $80 USD (~$122 AUD) all-in, three business days processing, single entry, 30 days in-country. It covers the entire leisure cohort that makes up the bulk of Australian arrivals to Cambodia: Angkor Wat trips, Koh Rong beach stays, Phnom Penh stopovers, Kampot pepper-farm visits, Battambang day-trips, family visits to relatives, weddings, food tours, and any holiday that fits inside 30 days. If your trip is leisure-led and you are staying 30 days or fewer, the T-Class is what you need. The Tourist eVisa specialist guide for Australians covers the application end to end.
The Business eVisa, written as Type E on the approval PDF and also referred to as the Ordinary visa in older Cambodian Immigration documentation, is the broader class. $90 USD (~$137 AUD) all-in, three business days, single entry on initial issue, 30 days in-country — and it is the only Cambodia visa that can be extended in-country in 1, 3, 6, or 12-month blocks. The Business eVisa covers meetings, paid work, conferences, supplier visits, due-diligence trips, sponsored events, digital-nomad stays longer than 30 days, retirement reconnaissance trips, and any structured business activity. The 'Ordinary' label is misleading to Aussies — it sits alongside the formal A, K, and B classes, not below them. The Business eVisa specialist guide for Australians has the full breakdown of what counts as business and what does not.
The remaining three classes exist on paper for completeness, but the eligibility door is firmly shut on ordinary Australian travellers. A-Class (Diplomatic) is reserved for accredited foreign diplomats, posted consular officers, and Ministry of Foreign Affairs officials travelling on a diplomatic passport. If you do not hold a diplomatic passport — and almost no Aussies do — you cannot apply for an A-Class regardless of how senior your civilian role is. K-Class is for people of Khmer descent returning to Cambodia long-term, with eligibility paperwork that proves Khmer lineage through one or both parents. It is a small but meaningful category for Khmer-Australian dual citizens but irrelevant to non-Khmer-heritage Aussies. B-Class is for foreign government officials travelling on official duty, UN postings, and accredited delegations holding an official (not diplomatic) passport. Like A-Class, it is closed to ordinary Australian civilian travellers.

This is the single most important practical fact about the five-class system in 2026: the Cambodian government's online eVisa portal only issues T and E classes. Nothing else. If you log in expecting to find a dropdown with five options, you will not — the dropdown has two. Tourist or Business. Anything you read on an out-of-date travel blog suggesting you can apply for an A, K, or B class online is wrong. Those three classes are issued exclusively through the Royal Embassy of Cambodia in Canberra, on the strength of eligibility paperwork that an ordinary Aussie tourist or business traveller does not have.
The practical consequence is clean: if your trip is a normal Aussie tourist or business trip, you apply online for T or E and you are done. If your trip somehow involves a diplomatic posting, a UN secondment, an official government delegation, or a long-term return on Khmer heritage grounds, you stop applying online and contact the Embassy directly. The Cambodia Embassy Canberra guide for Australians walks through the embassy process for the edge cases — though if you are reading this looking for your own tourist trip, that guide is not what you need.
The eVisa portal's two-class limit is also why the persistent confusion around 'Ordinary visa' is worth clearing up. The Business eVisa and the Ordinary visa are the same product — same E-Class code, same $90 USD price for Aussies, same 30-day initial stay, same in-country extension menu. 'Ordinary' is the formal class name in Cambodian Immigration documentation; 'Business' is the everyday label on the eVisa portal. When an Aussie reads 'Ordinary visa' on an immigration policy document, that is the E-Class they would also see as the Business option at checkout.

Because the real decision is always T or E for almost every Aussie, here is the practical decision flow we run on the application desk every working day. Five quick questions, mapped to the right class. If you can answer them honestly, you almost never pick wrong.
Question one: is your stay 30 days or fewer? If yes, continue. If no — you are planning longer than 30 days — you need the Business eVisa from the start, because the Tourist eVisa cannot be extended in-country since November 2025. Skip the rest of the questions and apply for E.
Question two: does any part of your trip involve paid work? Remote work for an Australian employer counts. Freelance assignments count. Paid speaking gigs count. Sales calls count. If yes, you need the Business eVisa. If no, continue.
Question three: are you attending business meetings, supplier visits, conferences, or sponsored events? Even a single half-day of meetings, a one-off conference, or a single supplier site visit pushes the trip into Business class. If yes, you need the Business eVisa. If no, continue.
Question four: are you doing any kind of structured commercial activity — due diligence, investor scouting, factory inspections, training delivery, board meetings? If yes, Business eVisa. If no, continue. Question five: is the rest of your trip leisure — Angkor Wat, Koh Rong, family visits, food, beaches, sightseeing? If yes, Tourist eVisa is the right answer. If you answered yes to any of questions one through four, you are an E-Class trip; otherwise you are a T-Class trip. The T vs E detailed comparison for Australians has worked Aussie scenarios for each combination if your trip sits on the edge.

When you land at Phnom Penh (KTI), Siem Reap (SAI), or Sihanoukville (KOS), the immigration officer at the desk scans the QR or barcode on your eVisa PDF. The scanner returns your visa class code — T or E — and that letter goes straight into the Cambodian Immigration trip log against your passport number. The officer sees the class on their screen before they ask you anything. If you printed a Tourist eVisa and the officer asks 'purpose of visit?' your answer needs to match the class on screen. 'Tourism, Angkor Wat, a week with family' matches T. 'Three days of meetings then four days at Angkor' does not — the meetings part should sit on an E-Class.
The class code also matters for audit trail. Cambodian Immigration retains the class scan for every entry on your record, and the trip log is what gets pulled if you apply for a subsequent visa, an extension, or a future entry. A clean record of T-class entries reads as a normal Aussie leisure traveller. A T-class entry followed by an extension attempt or a long overstay reads as a mismatch and gets flagged. An E-class entry followed by extensions reads as a normal long-stay business pattern. The class is not just for the day of arrival — it is the long-term tag on your immigration history with Cambodia. The eVisa vs Visa on Arrival comparison covers how the arrival method affects which class shows on the entry stamp, and the Australian application walkthrough has the upfront online form for both T and E.

First trip to Cambodia? Here is the honest first-timer checklist for Americans — the visa, the US-dollar money quirk, the safety reality, the vaccines, the temple dress code, and what arrival at the new airport actually looks like in 2026.
All seven Thailand–Cambodia land borders have been closed since June 2025, so in 2026 the only way for Americans to get from Thailand into Cambodia is to fly.
