Saigon to Phnom Penh by Bus in 7 Hours: The Aussie Border Playbook for 2026
The Saigon-to-Phnom Penh bus is the cheapest, fastest, and most-used overland route into Cambodia for Aussies in 2026. Seven hours, twenty US dollars, one printed eVisa — here's the field-tested version.
How do Australians cross from Saigon to Phnom Penh by bus in 7 hours?
You board a tour bus in Ho Chi Minh City's District 1 around 6:30am to 8:30am, you ride two and a half hours south-west to the Moc Bai border, you get your Vietnamese exit stamp (the bus attendant on Mekong Express or Giant Ibis runs the passports for you), you walk a short distance across no-man's-land, you hand your printed Cambodia eVisa to the Bavet immigration officer for your entry stamp, you reboard, and you arrive in central Phnom Penh roughly seven hours after departure. Total cost $15 to $25 USD (~$23 to $38 AUD) one-way. The Cambodia eVisa is $80 USD (~$122 AUD) all-in and approved in 3 business days. You do not need a Cambodia e-Arrival Card for the land crossing.

- If you do use VoA at Bavet, bring $35 USD (~$53 AUD) in clean post-2006 small notes plus one 4cm x 6cm passport photo. No card payments. No phone snaps.
- You do not need the Cambodia e-Arrival Card for the Bavet land crossing — only for air arrivals into KTI, SAI, and KOS.
- Best Aussie operators are Mekong Express and Giant Ibis, both running passport-runner systems where the attendant handles Vietnamese exit stamps for you on the bus.
Why the Saigon-to-Phnom Penh bus is the default Aussie route in 2026
Of every Australian who crosses into Cambodia overland in 2026, the single biggest share is doing it on a tour bus out of Ho Chi Minh City. The numbers tell the story. Thailand–Cambodia land crossings have been closed since June 2025, with no reopening on the calendar. Laos is a quieter northern route used mainly by backpackers coming south from Luang Prabang. Vietnam–Cambodia, specifically the Bavet–Moc Bai crossing on Highway 1 between Saigon and Phnom Penh, is the workhorse.
I have personally done this crossing more than thirty times since 2019. The rhythm has barely changed in five years. The visa policy around it has changed more — particularly the rise of eVisa preference over VoA — and the broad message in 2026 is the same one we have been giving Aussie clients for years: apply for the eVisa before you board, do not rely on the Bavet VoA queue. The eVisa is faster end-to-end and removes the single biggest risk on the day.
The 7-hour journey, broken down
The bus journey splits cleanly into four phases: the early-morning Saigon leg, the Vietnamese exit at Moc Bai, the Cambodian entry at Bavet, and the run into Phnom Penh. Each one is roughly the length you would guess. Here is what an Aussie can expect from each.
The Saigon morning leg
Mekong Express and Giant Ibis both run early-morning departures from offices on or near Pham Ngu Lao Street in District 1, Saigon. Most services pull out between 6:30am and 8:30am. The deliberate early start is to land at the border before Cambodian Immigration's slower afternoon shift kicks in around 3pm. Aim for the morning, not an overnight — the few overnight services that exist do not save you time and cost you a sleep cycle.
The Bavet entry
This is the only part of the day where your visa choice really matters. If you have an eVisa printout, you join the eVisa lane: 20 to 40 minutes for a full bus. If you arrive without one and try the VoA route at Bavet, you join the on-arrival queue with 30 to 60 minutes of waiting, $35 USD (~$53 AUD) in clean small notes, and a 4cm x 6cm passport photo. The maths is straightforward: the eVisa is faster on the day and adds only $45 USD (~$69 AUD) to your trip cost end-to-end.
Häufig gestellte Fragen
How long is the bus from Ho Chi Minh City to Phnom Penh?
Around 7 hours door to door on the premium operators (Mekong Express, Giant Ibis): 2.5 hours from Saigon to Moc Bai, roughly 1 hour at the Moc Bai–Bavet border crossing including the walk across no-man's-land, then 2.5 to 3 hours from Bavet into central Phnom Penh. The cheaper operators (Kumho Samco, Sapaco) can stretch to 8 or 9 hours, mostly because of slower border handling.
How much does the Saigon-to-Phnom Penh bus cost in Australian dollars?
Expect $15 to $25 USD (~$23 to $38 AUD) one-way for the ticket itself. Mekong Express and Giant Ibis sit at the top of that range at $18 to $25 USD (~$27 to $38 AUD) for reclining seats, AC, wifi, snacks, and an English-speaking attendant. Kumho Samco and Sapaco are cheaper at $12 to $18 USD (~$18 to $27 AUD) but less consistent. The Cambodia eVisa is a separate $80 USD (~$122 AUD) all-in, paid online to us a week or more before you board.
Do I need a Cambodia eVisa to cross at Bavet, or can I get visa on arrival?
You can do either, but the eVisa is materially faster on the day. Bavet visa-on-arrival carries a documented 30 to 60 minute queue and a smaller but real risk of temporary sticker stockouts. The eVisa is $80 USD (~$122 AUD) all-in, approved in 3 business days, delivered as a printable PDF by email, and lets you clear the Cambodian-side desk in 20 to 40 minutes for the full bus. Apply before you board in Saigon.
What do I need to bring if I use VoA at Bavet instead of an eVisa?
Bring $35 USD (~$53 AUD) in clean post-2006 USD notes — undamaged, no marker pen, no torn corners. Bring one 4cm x 6cm passport-style photo with a plain white background. No card payments are accepted at the booth. No phone-screen photos. If your notes are damaged or your photo is the wrong size, you are turned away. Plus the 30 to 60 minute queue. The eVisa is faster and removes all of this on-the-day risk.
Do I need the Cambodia e-Arrival Card for the Bavet land crossing?
No. The Cambodia e-Arrival Card is mandatory only for air arrivals into Phnom Penh (KTI), Siem Reap (SAI), and Sihanoukville (KOS). For the Bavet land crossing, the Cambodian Immigration desk handles entry directly using your printed eVisa and passport. If your wider trip includes a later return flight through any of those three airports, you do need the e-Arrival for that flight — submitted within the 7-day window before the flight.
