Looping Indochina in 2026? Every land re-entry into Cambodia needs a fresh eVisa — your existing one is consumed the moment you cross. Here's the Bavet and Tropaeng Kreal playbook for Aussies on the second, third, or fourth pass through.

Bring a fresh Cambodia eVisa each time — your existing single-entry eVisa is consumed by your first entry. The eVisa is $80 USD (~$122 AUD) all-in Tourist, $90 USD (~$137 AUD) Business, approved in 3 business days. You can apply from inside Vietnam or Laos. Land borders also offer VoA ($30 USD cash) but sticker stockouts at Tropaeng Kreal and informal "facilitation fees" at both crossings make pre-applied eVisa the safer call. The e-Arrival Card is NOT required for land entry (air-arrival only) — but you do need a fresh blank page and 6 months passport validity at each crossing.
The Indochina loop has become the default 2026 Aussie itinerary for anyone with three to six weeks of leave. Saigon in, Phnom Penh, Siem Reap, hop into Laos for Si Phan Don and Luang Prabang, then back south through Vietnam to fly home from Hanoi. With every Thai–Cambodian land border still closed, that loop now relies entirely on the two open overland gateways: Bavet from Vietnam and Tropaeng Kreal from Laos. The Thailand–Cambodia border closure update has the broader context for travellers who came here expecting Poipet to still be a thing.
What trips up most Aussies on the second pass is the visa rule that nobody mentioned the first time around: the Cambodia eVisa is a single-entry document. The moment you cross at Bavet or Tropaeng Kreal on the way in, your eVisa is consumed. Exit Cambodia on day five, try to walk back in on day twelve, and the officer at the booth needs to see a brand-new approval. The Cambodia eVisa multiple-entry rules cover the broader policy in detail, but the headline is simple: there is no multi-entry eVisa in 2026, and every re-entry by land needs its own fresh $80 USD application.
Bavet is the busy crossing. Most Indochina loops come back through here because Saigon is the natural launchpad for the return flight, and Mekong Express and Giant Ibis run the HCMC–Phnom Penh route hourly with the passport-runner system that takes most of the friction out of the border. For a returning Aussie, the booth itself is the same as the first time — printed eVisa PDF, passport, blank page, entry stamp, fifteen to thirty minutes per bus. The only difference is that the officer will sometimes glance at your prior Cambodian exit stamp and want to confirm you have a new eVisa rather than trying to re-use the old one. Our Bavet–Moc Bai field guide covers the bus operators and the broader logistics.
Tropaeng Kreal is the quiet crossing. Two open-fronted timber shelters on Highway 13, a handful of food stalls, and a queue that rarely exceeds twenty people. The trade-off for the calm is that the booth itself is the least reliable VoA point in Cambodia and the informal 'facilitation fees' show up here more often than at Bavet. For a returning Aussie with a fresh pre-applied eVisa, this is largely irrelevant — the officer simply checks the PDF, stamps the passport, and waves you through. For anyone arriving without a visa hoping to use VoA on the way back in, this crossing is where the wheels most often come off. Our Tropaeng Kreal field guide

The single rule that catches Aussies on the second application is the physical-location requirement. The Cambodia eVisa must be applied for from outside Cambodia — you cannot file the fresh one from a Phnom Penh hotel the day before you exit. The portal itself does not geolocate you, but the approval will not issue if the system detects an active Cambodian entry stamp on your passport. The clean workflow is: exit Cambodia on day five, sit down in a Saigon or Vientiane cafe on day six, file the new application, and let the three-business-day clock start from there. Our Australian application walkthrough takes you through the form field by field.
Practical tip from the desk: file the application on a laptop, not a phone, and use a stable wifi connection at your guesthouse rather than mobile data. The portal occasionally times out on slow connections and forces you to re-enter the form. The Australian application walkthrough has the field-by-field detail. The Cambodia eVisa for Australians page has the all-in fee breakdown, and the broader pillar on do Australians need a Cambodia visa covers the eligibility picture for first-timers and returners alike.

Fourth, USD cash matters more at the land borders. The airport has functioning ATMs and accepts card for most purchases inside the terminal. The land crossings do not — the booth wants USD, the nearest reliable ATM is hours away, and the money changers at the border have rates roughly 12% below market. Carry a $50 to $100 USD buffer in clean small unmarked notes, post-2013, for both crossings. The eVisa vs VoA comparison has the broader cost picture.
