Cambodia e-Arrival for Aussies on Multi-Country Loops: One Card per Entry

How the portal remembers your details between Cards

On the same login email, the Cambodia e-Arrival portal remembers your last submission's passport block and contact details. When you return to file the second Card, the passport number, full legal name, date of birth, and nationality pre-fill from the previous Card. The contact email and phone number also carry across. This is helpful — the personal block typically takes 4–5 minutes to fill from scratch, and on the second submission those fields populate in a couple of clicks.

What does not carry across

The flight-specific fields are blank on each new Card. The new flight number, the new arrival date, the new arrival airport (KTI, SAI or KOS — could be different from your first entry), and the new accommodation are all manual entries. The customs and health declaration boxes are not pre-ticked either; you re-tick them on each submission. So even with the portal's memory, each subsequent Card still takes around 6–8 minutes to complete properly.

Using the same email is the trick

The memory only works if you log in to the portal with the same email you used for the first Card. If you accidentally use a different email — or the portal forces a fresh session and you sign up again — none of the prior data pre-fills, and you are back to the full 12-minute form. Aussies who use a family-organiser email for the first trip should make a note to use the same one for the second Card; it saves real time across a multi-Card loop.

The visa side: each entry needs a valid visa too

The e-Arrival Card and the eVisa are two separate things. The eVisa is what authorises you to enter Cambodia. The e-Arrival Card is the immigration declaration filed against that visa for a specific arrival. You need both, on both entries, for a multi-entry loop.

A standard Cambodia tourist eVisa is single-entry, valid for 30 days. Once you cross out of Cambodia (whether by air or overland), the visa is consumed. For a second entry, you need either a fresh tourist eVisa filed before that leg or a multiple-entry business eVisa that covers multiple crossings. The choice depends on the trip purpose and frequency — most Aussies on a single Indochina loop file two single-entry tourist eVisas, one per entry. Frequent travellers consider the business multiple-entry route instead.

Tourist eVisa: $80 USD (~$122 AUD) per entry

The tourist eVisa is $80 USD (~$122 AUD) all-in, approved in 3 business days, delivered as a printable PDF by email. For a two-entry loop, that is two separate applications — one before the first entry, one before the second. Each issues its own approval letter and visa number. The validity is 3 months from issue, so both can be filed before the trip starts if the second entry is within that window.

Business multiple-entry: $90 USD (~$137 AUD) base

The business eVisa is $90 USD (~$137 AUD) for the base single-entry; the multiple-entry extension is purchased separately at the embassy or via an extension agent in Phnom Penh. Suited to meetings, paid work, conferences, sales calls, supplier visits, and long stays — not strictly a tourism instrument. For Aussies whose loop has them in and out for business reasons (meeting in Phnom Penh, supplier in Ho Chi Minh, follow-up in Siem Reap), the business route opens up multiple-entry, but it is over-engineering for a pure tourism loop.

The Cambodia eVisa types explained guide covers the choice between tourist and business in detail, and the Cambodia eVisa multiple-entry guide covers the specific multiple-entry routes for Aussies on repeat trips.

The order to file e-Arrival Cards across an Indochina loop

The single most important rule is that each Card is filed inside the 7-day window before the arrival it covers — not all at once before the trip starts. The portal rejects submissions more than 7 days ahead of the listed arrival date. So a two-entry loop spread across three weeks means filing the Cards on two separate dates, each in the week before that specific Cambodia arrival.

Step 1 — File the first Card 5–7 days before initial entry

Roughly a week before flying into Cambodia for the first time, file the first e-Arrival Card. Use the airport you are actually flying into (KTI for Phnom Penh, SAI for Siem Reap, KOS for Sihanoukville), your inbound flight number, and the accommodation booked for that first stay. Save the QR code to Apple Wallet or Google Wallet, labelled with the trip name and date.

Step 2 — Travel through Vietnam (or wherever the loop goes)

While in Vietnam, Laos, or wherever the middle leg of the loop takes you, leave the second e-Arrival alone. The 7-day window for it has not yet opened. Trying to file early returns an error on the portal — the system checks the date you enter against the system clock and rejects submissions too far in advance. Mid-trip is also when most Aussies forget about the second Card, so a calendar reminder seven days before the next Cambodia entry is a sensible move.

Step 3 — File the second Card from your hotel WiFi mid-trip

Five to seven days before you fly back into Cambodia, log in to the e-Arrival portal from your hotel WiFi in Vietnam or Laos. The portal recognises the email and pre-fills your passport block from the first submission. You enter the new flight number, arrival date, arrival airport, and accommodation for the second Cambodia stay. Submit. The new QR code lands in the same inbox alongside the first. Save it labelled clearly — same trip, second entry — so you do not confuse the two at the kiosk.

Step 4 — Onward to Laos or wherever the loop ends

If your loop ends with an overland exit (Tropaeng Kreal into Laos, Bavet into Vietnam), no further e-Arrival is needed for Cambodia. If you fly out and back in again — say, a side-trip to Bangkok for a stopover before final exit — that third air arrival into Cambodia needs a third Card. We have processed loops with three Cambodia air entries; the workflow is the same, just repeated.

The summary for Aussies doing the Indochina loop

Each Cambodia air entry needs its own e-Arrival Card, filed inside the 7-day window before that specific arrival, with its own QR code carried separately. The portal remembers your passport on the same login email — the personal block pre-fills, the flight block is fresh on each submission. Each Card is $5 USD (~$7.50 AUD) verified through us, no multi-trip discount, but free resubmission if Immigration flags a correction and Aussie-timezone support across the trip. The eVisa side is separate — single-entry tourist eVisas at $80 USD (~$122 AUD) per entry, or the business multiple-entry route at $90 USD (~$137 AUD) base for travellers in for meetings, conferences, sales calls or supplier visits. File the first Card a week before initial entry, the second from your hotel WiFi mid-trip a week before re-entry. Save every QR labelled by entry date in Apple Wallet or Google Wallet.
