When to Fill Out the Cambodia e-Arrival Card: Day-by-Day Timing for Australians
The Cambodia e-Arrival Card opens 7 days before your flight and not a day earlier. Here is the day-by-day timing for Australians flying Sydney, Melbourne, Brisbane or Perth — why Day 5 or 6 is the sweet spot, what happens if you try too early, and the paper-form fallback at the airport if you forget.
When should Australians fill out the Cambodia e-Arrival Card?
The portal opens 7 days before your arrival date in Cambodia, and Day 5 or Day 6 before arrival is the sweet spot for Australians — by then you have packed, you know your final flight and hotel, and you have not yet lost the QR code in your inbox. Too early (more than 7 days out) and the portal silently rejects you. Too late (at the gate) and the form does not load on flaky airport WiFi, so you end up on a paper-form fallback at the arrival airport, adding 20–30 minutes at KTI, SAI, or KOS. Each person needs their own submission. Our verified e-Arrival is $5 USD (~$7.50 AUD) per person, delivered as a printable PDF by email and checked end-to-end before it reaches Immigration.
نکات کلیدی
- The Cambodia e-Arrival opens exactly 7 days before your arrival date in Cambodia, not 7 days before you leave Australia — important for late-night Sydney and Melbourne departures.
- Day 5 or Day 6 before arrival is the Aussie sweet spot — you have your final flight, your final hotel, and you have not yet lost the QR code in your inbox.
- Filling too early — even by an hour outside the 7-day window — silently fails or returns a wait message. Filing at the gate is too late and means a paper-form fallback.
- If you forget entirely, you fill the equivalent paper form at the arrival airport — adds 20–30 minutes at KTI, SAI, or KOS Immigration after a 7-hour flight.

Why the day you fill it matters more than you think
The 7-day window: what it actually means for Aussies
Trying too early — the silent fail
Trying too late — the airport-WiFi trap
Day 5 or Day 6 before arrival — the Aussie sweet spot
You have packed and your plans are final
You have not lost the QR code yet
You have enough margin for a re-submit
The 'fill it from home, not from the gate' rule
If you remember nothing else from this article, remember this. Fill the e-Arrival from your home WiFi, with your passport on the desk and your eVisa PDF open. Do not leave it for the airport. Airport WiFi is patchy, your hands are full of bags, the email may not arrive before you board, and a kiosk arrival without a QR code is a 20–30 minute paper-form detour at the worst possible moment.

سوالات متداول
How many days before flying should I fill the Cambodia e-Arrival?
The portal opens exactly 7 days before your arrival date in Cambodia. Day 5 or Day 6 before arrival is the sweet spot for Australians — by then your hotel, flight, and packing are settled, but the confirmation email is still fresh in your inbox. Avoid Day 7 (no margin if plans change) and avoid the day of flight (airport WiFi is patchy, and the email may not arrive before you board). For most Aussies that means mid-week of the week before flying.
Is the 7-day window measured from departure or arrival?
Arrival, in Cambodian local time. For Aussies on overnight flights from Sydney or Melbourne (board Wednesday evening, land in Cambodia Thursday morning), the window opens 7 days before Thursday — not 7 days before Wednesday. Count from the day you actually land at KTI, SAI or KOS, not the day you take off. Perth travellers on same-day afternoon arrivals have a cleaner mental model since departure and arrival are the same calendar day.
What happens if I try to submit more than 7 days early?
The portal either returns a polite wait-message ('please submit within 7 days of arrival') or accepts the data but never issues the QR code email. Some Aussies misread the silent acceptance as a successful submission. There is no benefit to submitting early — the kiosk only reads the most recent submission for your passport — so wait until you are inside the window and file then. The kiosk does not care when you filed, only that you did.
Can I fill the e-Arrival at the airport before boarding?
Technically yes, but the airport-WiFi trap means it often does not work cleanly. Airport WiFi is patchy, the confirmation email may not arrive before you board, and once you are airborne you cannot retrieve it. The boarding announcement and the kiosk submit step do not mix well. The rule is fill from home, not from the gate. If you have genuinely forgotten until you reach the gate, board the flight and use the paper-form fallback on arrival — it is slower but cleaner than a half-submitted online form.
What if my flight changes after I have already submitted?
Re-submit. The kiosk reads the most recent submission for your passport number, and there is no penalty for re-filing inside the 7-day window. Update the flight number and arrival date, hit submit, and the new QR code arrives in 5–15 minutes. If you used our verified e-Arrival service, reply to the confirmation email with the new flight details and we re-file at no extra cost with Aussie-timezone support.
