A Mekong cruise from Phnom Penh to Saigon is the slowest, prettiest, and least-stressful way to do the Cambodia-to-Vietnam crossing. Operators handle the paperwork onboard — but Australians still need to sort both visas before they board.

You arrange both visas yourself before you board, even though the cruise crew handles the actual border paperwork onboard. Apply for the Cambodia eVisa ($80 USD / ~$122 AUD all-in, approved in 3 business days, delivered as a printable PDF by email) at least two weeks before your flight to Phnom Penh. Apply for the Vietnam eVisa ($25 USD / ~$38 AUD single-entry) about three weeks before sailing. Both arrive as PDFs. The cruise purser collects every passport onboard the day before the Kaam Samnar–Vinh Xuong river crossing, processes Cambodian exit and Vietnamese entry while you sleep, and returns the lot at breakfast. You also still need the Cambodia e-Arrival Card for the flight into KTI Phnom Penh.

Apply in this order
Apply for both visas in the same fortnight, but submit the Cambodia eVisa first — it carries the tighter 3-month validity window from issue, and you want the validity clock to start as close to your embarkation date as possible. Vietnam eVisa is valid for 30 days from your stated entry date, which usually lines up with the river crossing.

What the operators will not do
No cruise operator on the Mekong applies for visas on your behalf. They check, collect, present, and return. The application itself sits with you. If you turn up at embarkation without a Cambodia eVisa or Vietnam eVisa already approved, you will be denied boarding and your fare is non-refundable in most operator T&Cs.
