Cambodia Conference Attendance Visa for Australians: 2026 Guide for Speakers, Delegates & Exhibitors
Aussie conference travellers default to the Tourist eVisa for a two-day event — and that's a quiet $10 mistake. The Business eVisa (E-Class) at $90 USD (~$137 AUD) is the right class for any sponsored conference, panel slot, exhibition booth, or speaker invitation, even if you're in and out in 72 hours.
Which Cambodia visa do Australians need to attend a conference?
The Cambodia Business eVisa (E-Class) — $90 USD (~$137 AUD) all-in, 3 business days, even for a 2-day conference. Tourist eVisa technically restricts to leisure only; using it for a sponsored event can cause border-officer questions. The $10 difference from Tourist is cheap insurance and lets you legally claim conference attendance, speak on panels, run exhibition booths, and meet with sponsors. No invitation letter required at the application stage. Apply 10-14 days before the conference, file your e-Arrival 7 days before flight, print 2 copies of the eVisa PDF.
Key Takeaways
- Use the Business eVisa (E-Class), not the Tourist, for any Cambodian conference — whether you are a keynote speaker, panel speaker, delegate, exhibitor, or sponsor.
- $90 USD all-in (~$137 AUD), approved in 3 business days, valid 3 months from issue, 30-day stay on arrival — identical mechanics to the Tourist, just the right class for sponsored event attendance.
- The Tourist eVisa technically restricts the trip to leisure only; using it for a sponsored conference can cause border-officer questions. The $10 USD difference is cheap insurance.
- No invitation letter is required at the application stage — Cambodia's Business eVisa has an unusually light document pack. Apply 10–14 days before the conference, file your e-Arrival 7 days before flight, print 2 copies of the eVisa PDF.
- Class conversion in-country is not supported. If your conference dates shift, you can extend a Business eVisa through a Cambodian immigration agent; a Tourist eVisa cannot be extended (since November 2025).
Why Aussie conference travellers need Business, not Tourist
Phnom Penh's conference calendar has grown sharply since the new Techo International Airport opened in late 2025. ASEAN regional summits, mining and resources expos, fintech and digital-economy forums, NGO and capacity-build conferences, university and policy events at the Royal Palace Hotel and Sokha — Australia now sends more conference-bound travellers to Cambodia than at any point since 2019. Most of them book the Tourist eVisa by default. Most of them should not.
The Cambodia Business eVisa (E-Class) is the technically correct class for any conference attendance with a corporate, sponsored, or commercial element — and that covers almost every Aussie conference traveller. Keynote speakers, panel speakers, delegates flying in on a corporate ticket, exhibitors running a booth, sponsors hosting hospitality — all five sit cleanly inside the Business class. The $80 USD Tourist is built for leisure, family visits, and the Angkor / beach loop. The $10 USD price step to the Business eVisa is the cheapest piece of insurance a conference traveller will buy all year.
This is the conference-attendance guide for Aussie speakers, delegates, and exhibitors heading to Cambodia in 2026. The Cambodia Business visa for Australians anchor covers the full E-Class breakdown including extensions, the Business meeting-trip guide covers the same Tourist-vs-Business call for short executive trips, and the Tourist vs Business detailed comparison runs the side-by-side. For the wider entry question, the Do Australians need a Cambodia visa pillar is the place to start, and the Australia country pillar covers the broader eligibility picture.
The five conference roles — and the visa each one needs
Cambodian Immigration does not distinguish between conference roles at the visa-class level — keynote speaker, panel speaker, delegate, exhibitor, and sponsor all sit inside the same Business E-Class category. But the documents you should carry on the ground, and the questions an officer may ask at the e-Arrival desk, differ subtly by role. Below is the working attribute table we hand Aussie conference travellers.
Frequently asked questions
Which Cambodia visa for a conference?
The Business eVisa (E-Class), at $90 USD (~$137 AUD) all-in, approved in 3 business days. Even for a 2-day conference, the Business eVisa is the technically correct class for any sponsored event attendance — keynote speaker, panel speaker, delegate on a corporate ticket, exhibitor, or sponsor. The Tourist eVisa at $80 USD covers leisure only; using it for a sponsored conference is a misclassification that can cause border-officer questions and creates corporate-travel-policy and travel-insurance issues.
Can I attend a conference on the Tourist eVisa?
Technically no. Cambodia treats sponsored or paid conference attendance — speaking, exhibiting, delegating on a corporate ticket, or sponsoring — as business-purpose travel. The Tourist eVisa is built for leisure, family visits, and sightseeing. The only conference scenario that arguably fits Tourist is a fully self-funded, personal-interest attendance at an open public event with no corporate angle whatsoever, and even there we lean Business for the $10 USD price step and the cleaner border presentation. If your employer paid the ticket, your sponsor paid the booth, or your honorarium is coming from the Cambodian organiser, it is Business class travel.
Do I need an invitation letter from the conference?
No, not at the application stage. The Cambodia Business eVisa is unusually light on documentation — no sponsor letter, no Cambodian company invitation, no employment contract, no return flight, no hotel booking, no bank statement. The application asks for your passport, a fresh passport-style photo, an email address, and a payment method. That said, carrying a printed copy of your conference invitation, speaker confirmation, or registration receipt on the ground is a sensible precaution if Cambodian Immigration casually asks 'purpose of visit' at the desk.
Can I claim conference fees as an Aussie business expense?
Almost always yes — the conference registration fee, the $90 USD Business eVisa fee, the flights, the hotel, and reasonable hospitality are all standard business-travel line items under nearly every Australian corporate travel policy and ATO guideline for genuine work-related conference attendance. The Business eVisa receipt is actually easier to expense than the Tourist for a conference trip, because it removes any internal-audit query about why a leisure visa was used for a sponsored event. We are not tax advisors — check with your accountant on the specifics for your role and entity — but the general pattern is clean and well-established.
