カンボジア逆戻り旅行：Aussieの多国一周ループについてのe-Arrival
あなたはインdochinaループ（カンボジア→ベトナム→カンボジア→ラオス）を運行中です。カンボジアへの再入国たびに、その区間の7日前に独自のe-Arrival Cardを提出する必要があります。このポータルがどのように詳細を記憶し、何が変わるか、旅程全体でどのように提出するかについてご説明します。
カンボジア→ベトナム→カンボジア→ラオスのAussieは複数のe-Arrival Cardが必要ですか？
Yes — one Card per entry into Cambodia. A two-entry loop means two e-Arrival Cards, each filed inside the 7-day window before that specific arrival. The portal remembers your passport on the same login email, so the second submission pre-fills the personal block, but you re-enter the new flight number, arrival date, arrival airport, and accommodation by hand. The visa side is separate: a single-entry eVisa is used up on the first entry, so the second Cambodia entry needs a fresh eVisa or a multiple-entry option. Each e-Arrival Card is $20 USD (~$31 AUD) verified through us, with no multi-trip discount on the form itself. The Cards are filed sequentially through the loop, not all at once — the portal rejects submissions more than 7 days before the arrival date. Our verified e-Arrival is delivered as a printable PDF by email, with free resubmission if Immigration flags a correction and Aussie-timezone support across the trip.
主なポイント
- カンボジアへの空路での入国ごとに、その入国日の7日以内に提出された独自のe-Arrival Cardが必要です。2回のカンボジア入国が含まれる多国一周では、2枚のカードが必要です。
- ポータルは同じログインメールで前回のパスポートとフライトを記憶しています。2枚目のカードを申請に戻ると、パスポート欄は自動入力されますが、フライトと日付欄は新しい区間のために空白になります。
- Each Card is $20 USD (~$31 AUD) verified through us. The second entry is the same fee as the first; there is no multi-trip discount on the e-Arrival itself.
- ビザ側はe-Arrival側とは別物です。.single-entry eVisaは最初の入国で使用済みになります。カンボジアへの帰路には、新しいeVisaまたは複数回国許可オプションが必要です。
- 各e-Arrival Cardはその区間の7日以内に出入国Specific 入国日の7日以内に提出してください。一度に全て提出しないでください。ポータルは入国日の7日前に提出されたカードを受け付けません。
- Our verified e-Arrival is $20 USD (~$31 AUD) per Card, delivered as a printable PDF by email, with free resubmission if Immigration flags a correction and Aussie-timezone support for loop bookings.
2026年のAussie多国一周ループにとってこれが重要な理由
2025年6月にタイ·カンボジア間の陸路国境が全て閉鎖されて以来、インdochina一周はAussie旅行者の間で人気が高まりました。陆路タイ入国ができなくなったことで、一般的なAussieの3カ国一周はベトナムとラオス経由でルート変更されています—KTI経由のプノンペン入国、ベバット経由でベトナムへ陸路移動、バスまたは飛行機でカンボジアに再入国、そしてトロペアンクリアル国境経由でラオスへ南下。2週間で2回または3回のカンボジア入国は、もはや珍しくないになっています。
What catches Aussies off-guard is that the e-Arrival Card is per entry, not per trip. The mental model many travellers carry — fill the form once, it covers the whole trip — does not apply. Each time you cross into Cambodia by air, the kiosk expects a fresh Card filed against that specific arrival. Overland re-entry (Bavet, Tropaeng Kreal) is the exception — the e-Arrival is currently an air-arrival requirement, so the second land-side entry usually does not need a Card. But any air re-entry does.
This guide covers the multi-entry workflow: how the portal remembers your details between submissions, what changes on each Card, what stays the same, the visa side of the loop, and the order to file across a typical Indochina circuit. If you are new to the form itself, the Cambodia e-Arrival 14-fields walkthrough is the field-by-field reference, and the Cambodia frequent traveller visa strategy is the broader planning piece for Aussies on the second or third visit. For the full eligibility picture, the official Cambodia eVisa for Australians hub is the canonical source.
The one-Card-per-entry rule for air arrivals
Cambodian Immigration treats every air arrival as a fresh entry event. The e-Arrival Card is tied to that specific arrival date, airport, and flight. If you fly in, fly out to Vietnam, then fly back in three days later, the second air arrival is its own event and needs its own Card. The Card you filed for the first entry has been consumed; the kiosk for the second arrival will not find a matching Card on file unless you have filed a fresh one for the new date.
Land re-entry is the practical exception. The e-Arrival Card is currently only required at the three air entry points — KTI, SAI, KOS. If your loop has you flying into Cambodia, exiting overland via Bavet to Vietnam, and re-entering overland via the same Bavet crossing on the way back, the return is not an air arrival and does not need a Card. The Cambodian land-border process for Aussies is its own paperwork (a paper arrival card filled at the crossing), but the digital e-Arrival is not triggered.
Why land and air are treated differently
The e-Arrival system was rolled out specifically for the three international airports — KTI replacing PNH in September 2025, plus SAI and KOS. Land crossings still operate on paper-based arrival cards filled at the border post. The kiosks at KTI, SAI and KOS read the QR code on arrival; the booths at Bavet and Tropaeng Kreal read a paper form. So a fly-in-overland-out trip needs one Card. A fly-in-fly-out-fly-back trip needs two. An overland-overland-back loop needs one (just for the first air arrival).
よくある質問
I am doing Cambodia → Vietnam → Cambodia → Laos. How many e-Arrival Cards do I need?
Two. One Card per Cambodia air entry. The first Card covers your initial arrival into Phnom Penh, Siem Reap or Sihanoukville. The second Card covers your re-entry into Cambodia from Vietnam (assuming the second entry is by air — if you cross back overland via Bavet, the e-Arrival is not triggered). The Laos leg afterwards is not a Cambodia entry, so no third Card is needed unless you fly back into Cambodia from Laos later.
Can I file both e-Arrival Cards before the trip starts?
No. The portal rejects submissions more than 7 days before the listed arrival date. So if your second Cambodia entry is 14 days after your first arrival, the second Card cannot be filed yet at the time of the first arrival — the system will return a date-out-of-window error. The cleanest workflow is to file the first Card a week before initial entry, then file the second from your hotel WiFi mid-trip, roughly a week before the re-entry.
Does the Cambodia e-Arrival portal remember my details across multiple submissions?
Yes, on the same login email. The passport block (number, full legal name, date of birth, nationality) and contact details pre-fill from your previous Card. The flight-specific fields — flight number, arrival date, arrival airport, accommodation — are blank on each new submission and you re-enter them by hand. The customs and health declaration boxes are not pre-ticked. The memory saves about 4–5 minutes per Card across the trip.
Do I need a fresh eVisa for the second entry into Cambodia?
Yes, if your first eVisa was single-entry — which is the default for the tourist eVisa. Single-entry visas are consumed on the first crossing, so the second entry needs a fresh tourist eVisa at $80 USD (~$122 AUD), approved in 3–5 days, delivered as a printable PDF by email. The alternative is a business eVisa with the multiple-entry option, suited to travellers in for meetings, conferences, sales calls or supplier visits — but for pure tourism loops, two single-entry tourist eVisas is the cleaner route.
My second Cambodia entry is overland from Vietnam via Bavet. Do I need an e-Arrival Card for that?
No. The e-Arrival Card is currently only required at the three air entry points — KTI, SAI, KOS. Overland entries via Bavet (from Vietnam) or Tropaeng Kreal (from Laos) use a paper arrival card filled at the border post, not the digital e-Arrival. So a loop that exits Cambodia by air and re-enters overland needs only one e-Arrival Card (for the initial air arrival). You still need a valid visa for the overland re-entry — that side is unchanged.
