How an Aussie Applies for a Multi-Entry Business eVisa to Cambodia (Step-by-Step, 2026)

What lands in your inbox 3–5 days later

3–5 days after the application is paid and submitted, the approved visa lands in your inbox as a printable PDF attached to a confirmation email. The PDF is a single A4 page with the Cambodian visa stamp imagery, your photo, your passport number, your name, and the visa conditions clearly printed across the centre of the page.

Three sentences on the PDF deserve a careful read. First, the entry type line states 'Multi-entry, valid 12 months from first entry, 30 days per stay' — that's the headline condition. Second, the validity start line shows the date of first entry as 'on first use' rather than the date the PDF was issued — which means the twelve months only begin counting from the day you first land at KTI, SAI, KOS, Bavet, or Tropaeng Kreal. Third, the stay length line confirms each individual stay is capped at 30 days, with no in-country extension available on the multi-entry product.

Using the multi-entry visa once you are on the road

The first entry is the moment that starts the twelve-month clock. You hand the printed PDF to the Immigration officer at KTI in Phnom Penh, SAI in Siem Reap, or KOS in Sihanoukville, your passport gets stamped with an entry date, and the multi-entry permission becomes live for twelve months from that date. The officer notes your stay is single-entry-capped at 30 days, regardless of the multi-entry status — leaving and re-entering is what gives you more time in country, not staying past 30 days on one go.

Re-entries during the twelve months are simple. You leave Cambodia on the same PDF, fly somewhere — Bangkok, Singapore, Ho Chi Minh, anywhere — and when you re-enter Cambodia, you hand the same PDF back to the Immigration officer. They confirm the multi-entry validity date on the PDF, stamp you in for a fresh 30-day stay, and you carry on. No new visa, no fresh fee, no fresh application.

Two operational details Aussies miss. First, every air arrival into Cambodia still needs an e-Arrival Card submitted in the 7-day window before flight — that's mandatory on the first entry and on every re-entry afterwards. The e-Arrival is a separate 14-field form, $20 USD (~$31 AUD) for our verified version, Checked end-to-end before it reaches Immigration. Second, your final exit must happen on or before the twelve-month anniversary of the first entry — if you overstay the multi-entry window, the standard Cambodian overstay fines apply and you need a fresh visa to come back.

Edge cases Aussies run into on the multi-entry product

Three Aussie-specific patterns come up regularly on the multi-entry desk. The first is passport renewal mid-window. If your Australian passport expires during the twelve-month multi-entry validity, you need a new passport from DFAT before you fly back in. The multi-entry visa is tied to the passport it was issued against — once you have the new passport, the cleanest path is a fresh application, since the old PDF will no longer match the bio page Immigration scans on arrival.

The second pattern is purpose-of-travel changes. The multi-entry Business eVisa is approved against a stated purpose at application time. If your work shifts substantially across the twelve months — a Perth engineer who started on supplier visits and then takes on a paid sponsored speaking engagement in month seven, for example — the existing visa generally covers the broader Business category, but document any new engagement letter at re-entry just in case the officer asks. The Business class is deliberately broad: meetings, paid work, conferences, sales calls, supplier visits, due-diligence, long stays, and sponsored events all sit inside it.

The third pattern is the dual-citizen question. If you hold an Australian passport and one other passport, apply on the Australian one — Australian travellers get the smoothest processing on our Aussie desk and the broadest support if anything needs a fix. Once you start a multi-entry window on one passport, every re-entry needs to be on that same passport. Switching mid-window between passports is what causes problems at Immigration, not the existence of a second passport.
