Australians need three things to enter Cambodia in 2026: a passport with enough validity, a Cambodia visa and an e-Arrival Card for every traveller. Here is what each one involves, the order to sort them in and what happens when you land.

Australians need a passport valid for at least 6 months from arrival with a blank page, a Cambodia visa (most use the eVisa: $80 USD Tourist, 3–5 days) and a Cambodia e-Arrival Card filed in the 7 days before landing. At the airport, show your passport, visa and e-Arrival QR code to Immigration.
Entering Cambodia from Australia is straightforward once you know there are three separate pieces to sort out, and that they happen at different times. The passport is checked first, the visa comes next, and the e-Arrival Card is the last job, done in the final week before you fly.
The visa and the e-Arrival Card are the two that people confuse, because both are completed online and both end in something you show at the airport. They are different documents doing different jobs, and Australians need both on every trip.
Your passport should be valid for at least 6 months beyond your arrival date in Cambodia, with at least one blank page. Check the expiry date before you pay for anything, because a passport that runs out too soon means renewing it first and then applying for the visa on the new passport.
Australian passport holders need a visa to enter Cambodia. The eVisa is the route most Australians take because it is approved before you leave home, so you land with the question already settled.
The Tourist eVisa allows a stay of up to 30 days from entry and is valid for 90 days from the date it is issued. What you need to apply is short: your passport, a clear scan of its bio page and a payment card. You do not need a flight ticket, hotel booking or bank statement, and we do not need a photo. The approved eVisa arrives by email as a PDF. Print copies to carry with your passport.
A visa on arrival is also available at Cambodia’s airports, but it means queuing to apply and pay after a long flight from Australia. With an eVisa, that part is done before you leave.
The full detail for Australian passport holders, including the difference between the Tourist and Business visa, is on our Cambodia visa for Australian citizens page.

The e-Arrival Card is the requirement many Australians do not know about until close to departure. In 2024 it replaced the paper immigration arrival card, health form and customs declaration with one online form. Every traveller flying into Cambodia files it, including those who already have a visa. It is not a visa itself, and it does not replace one.
It can only be submitted within the 7 days before you arrive. To complete it you need your passport, the flight that lands in Cambodia, your arrival airport, where you are staying, a short health and customs declaration, and two newer details: your departure date from Cambodia and your next destination. If you file with us and have not booked onward travel yet, you can say “not booked yet” and we will email you to add the details later.
Once submitted, the card produces a QR code. Save it somewhere you can reach without Wi-Fi: a screenshot on your phone and a printed copy in your passport wallet covers every situation.
We file the Cambodia e-Arrival Card for Australians and check every field against your passport before it is submitted. If you book early, we hold your details and file the moment the 7-day window opens, then email you the QR code.
Still unsure whether it applies to you? Our short answer on whether Australians need the Cambodia e-Arrival Card covers repeat visitors, dual citizens and visa-on-arrival travellers.
Confirm it has at least 6 months of validity from your arrival date and a blank page. Renew it first if it does not.
Apply for the eVisa with time to spare. Approval takes 3–5 days, and an application sent at the weekend starts processing on the next Cambodian business day.
The form opens 7 days before your arrival date. File once your flights have stopped changing, for every traveller in your party.

One timing quirk for Australians: Cambodia runs three hours behind Sydney and Melbourne on standard time and one hour behind Perth, and your arrival date is a date in Cambodia. Filing on the very first evening the window seems open from Australia may be treated as a day too early, so leave a margin.
When your flights are fixed and the window is open, file your e-Arrival Card now and the QR code will be in your inbox before you head to the airport.
Cambodia’s e-Arrival system lists three international airports: Techo International (KTI), which replaced Phnom Penh International (PNH) in September 2025, Siem Reap Angkor International (SAI) and Sihanoukville International (KOS). Many Australians connect through Singapore, Bangkok or Kuala Lumpur. On the e-Arrival Card, enter the flight that lands in Cambodia, not your first flight out of Australia.
If you were planning the overland Bangkok-to-Siem Reap route, note that the Thailand–Cambodia land border has been closed since 2025, so you will need to fly in instead. Travellers crossing from Vietnam or Laos have reported completing paper arrival forms at the border rather than the e-Arrival Card. Land and sea rules are less clearly published, so confirm the process for your crossing before you travel.
Arrival is simpler than it used to be, because the forms are done before you board. Have three things in your hand as you walk to Immigration: your passport, your visa and your e-Arrival QR code.
If you notice a mistake on your card before you reach the desk, you can still edit and resubmit it, as long as Immigration has not yet processed you. Once you have been processed, it is too late to change.

Every person in your party travels on their own passport, so the paperwork is per person. We apply for a visa for each traveller, children included, and we file a card for every traveller in a party, babies included, because each one travels on their own passport. Collect everyone’s passports before you start and do them in one sitting.

Whether you need a Cambodia e-Arrival Card (and a Cambodia eVisa) during a layover at Techo International Airport (KTI) or Siem Reap (SAI) depends on one question: will you cross the immigration line? Here is the exact 2026 rulebook for airside transfers, separate tickets, and domestic hops.
