Cambodia Multi-Entry: the Laos Tropaeng Kreal Loop for Australian Travellers

Pairing Cambodia single-entry with Laos visa-on-arrival

The visa stack for the Laos loop has two pieces and one important difference from the Vietnam version. On the Laos side, Australian passport holders are eligible for visa-on-arrival at Veun Kham — $35 USD (~$53 AUD) cash, issued at the booth in roughly fifteen minutes, valid for 30 days, single entry. Laos also offers a $50 USD (~$76 AUD) eVisa in advance but for a single Mekong-loop segment the VoA is faster and cheaper. On the Cambodian side, the same rolling single-entry Business eVisa pattern as the Bavet loop — file from outside Cambodia, $90 USD (~$137 AUD), three business days. The Cambodia eVisa multiple-entry rules cover the wider 2026 policy framing.

The cost maths for a typical two-week Mekong wildlife loop is straightforward. Two Cambodia Business eVisas at $90 USD (~$137 AUD) each is $180 USD (~$274 AUD). One Laos VoA at $35 USD (~$53 AUD) on the way in, no second Laos visa needed because you depart Laos overland for Cambodia rather than re-entering. Total visa stack for the loop: $215 USD (~$327 AUD). Add a Cambodia e-Arrival Card at $5 USD (~$7.50 AUD) for your initial Phnom Penh KTI air arrival and the round number is $220 USD (~$334 AUD).

Why the difference matters: Tourist auto-extension ended in November 2025. If your trip plan is longer than 30 days on a single Cambodia segment, you cannot extend a Tourist eVisa in-country anymore. The clean workarounds are either a fresh Tourist eVisa after exiting and re-entering (which is exactly the Laos loop), or a Business eVisa which can still be extended at Phnom Penh's GDI for $290-$340 USD (~$441-$517 AUD). For a typical Aussie wildlife loop with 10-14 days on the Cambodian side and 5-7 days on the Lao side, Tourist works fine. The Cambodia Business vs Tourist cost difference page has the deeper comparison.

The Tropaeng Kreal-Veun Kham crossing day by day

Plan the crossing as a full half-day even though the booth time itself is short. Most Aussies on this corridor are coming up from Stung Treng township in a hired van or shared minibus, leaving around 7am, reaching the Cambodian exit booth at Tropaeng Kreal between 8:30am and 9am. The booth runs the standard exit process — passport, eVisa PDF, exit stamp — in 10 to 15 minutes. There is no e-gate, no fast lane, no formal queue management; you walk up and the officer takes your passport across the counter. The booth is open 7am to 6pm and the last reliable processing time is around 5pm.

Once stamped out on the Cambodian side, you cross roughly 800 metres of sealed road through the no-man's-land. There is no shuttle and no covered walkway — you carry your bag through the sunlight, which on a wet-season afternoon can be a soaking experience. On the Laos side at Veun Kham, the visa-on-arrival booth processes your application in roughly fifteen minutes. The fee is $35 USD (~$53 AUD) for Australian passports, paid in cash. The officer will sometimes try to add a 'weekend fee' or 'after-hours fee' of $1 to $2 USD (~$1.50 to $3 AUD) if you are crossing outside peak hours — this is informal and travellers who politely push back usually have it dropped. Carry exact change.

From Veun Kham, the onward transport options are minibus to Si Phan Don (90 minutes, around $5 USD (~$7.50 AUD)), minibus to Pakse (2.5 hours, around $12 USD (~$18 AUD)), or pre-booked private car to either. Most Aussies on the wildlife loop spend three or four nights in Si Phan Don for the Mekong river-islands, the Khone Phapheng waterfall, and the Irrawaddy dolphins from the Lao side near Don Khon. The Laos overland crossing details cover the broader Pakse-to-Vientiane onward routing if your trip extends north.

Applying for the return Cambodia eVisa from Pakse

Once you are on the Lao side and settled into Si Phan Don or Pakse, the return Cambodia application follows the same rules as the Vietnam version. The Cambodia eVisa must be applied for from outside Cambodia, your passport must not show an active Cambodian entry stamp, and the three-business-day clock starts from submission. The clean workflow is exit Cambodia at Tropaeng Kreal on day three or four of your trip, spend two or three days at Si Phan Don, then file the return application from a Pakse guesthouse on day six or seven for a re-entry on day nine or ten. The Australian application walkthrough takes you through the form field by field.

Wifi reality check: Si Phan Don wifi is rough. The river-island guesthouses run on solar or generator power, the connection is shared across the property, and the photo-upload step of the Cambodian portal occasionally fails on slow connections. The clean approach is to overnight in Pakse for one night specifically to file the application — the larger hotels along Pakse Riverside have fibre wifi suitable for the application. Mobile data on a Lao SIM is the backup; the Lao Telecom or Unitel local SIM at around 30,000 kip (about $2 USD (~$3 AUD)) gives you 5GB of 4G that handles the upload cleanly. Avoid trying to file from a Don Det bungalow on shared satellite wifi unless you have unlimited patience.

The seven-day rule of thumb applies here even more than at Bavet because the corridor itself is slower. File the return application at least seven days before your intended re-entry. Three business days is the headline turnaround, the approval lands as a printable PDF by email, and free resubmission if Immigration flags a correction is built into the all-in price. Aussie-timezone support means you can check status during your daytime hours back home or in Laos. Most returning Aussies on this loop apply on a Monday from Pakse and cross back on the following Tuesday or Wednesday, which absorbs any Cambodian public-holiday slowdowns. The Cambodia eVisa for Australians page has the full all-in fee breakdown.

The return crossing itself is structurally identical to the outbound. Veun Kham exit stamp on the Lao side, walk the 800m no-man's-land, Tropaeng Kreal entry stamp on the Cambodian side. The officer scans the new approval PDF, checks the prior exit stamp to confirm you are returning rather than trying to extend, stamps the fresh entry, and you board the onward minibus to Stung Treng. The fresh 30-day clock starts at the new entry stamp. From Stung Treng you can either retrace south to Phnom Penh or push west to Mondulkiri for additional wildlife segments before the air leg home from KTI.

Three mistakes Aussies make on the Laos loop

After running the northern corridor desk for several hundred Aussies in the last year, three mistakes account for most of the bad days at Tropaeng Kreal-Veun Kham. All three are avoidable with a few minutes of forward planning before you leave Stung Treng or Si Phan Don.

• Underestimating USD cash needs. The Lao VoA is $35 USD (~$53 AUD) cash, no card option, no Lao kip accepted. The booth has no ATM. Bring $40 USD (~$61 AUD) per person in clean small notes — fives, tens, an occasional twenty. Aussies arriving with worn or marked notes have been refused at the booth and sent to the money-changer who charges roughly 12% below market. Aussies arriving with no USD at all have been turned around. Get the cash in Phnom Penh or Siem Reap before the drive north.
• Trying to apply for the return Cambodia eVisa from a Don Det bungalow. Si Phan Don wifi is genuinely unreliable for a portal application — the photo-upload step is the failure point. Overnight in Pakse specifically for the application day, or buy a Lao Telecom local SIM and use mobile data. The application must succeed on a stable connection or you risk losing the form data partway through and having to restart with a fresh payment authorisation.
• Arriving at the booth late in the afternoon. Tropaeng Kreal-Veun Kham officially runs 7am to 6pm but the last reliable processing on the Cambodian side is around 5pm. Aussies who chase a late-departure minibus from Pakse routinely arrive after 5pm and find the booth still nominally open but the officers visibly winding down — informal small fees become more common and processing slows. Aim to clear both booths before 3pm. If your minibus has slipped past the morning departure window, overnight in Pakse or in Stung Treng and cross fresh first thing the next morning.
