Cambodia Multi-Entry Business eVisa Rules for Australians: 2026 Guide

Why Australians ask about multi-entry Business in 2026

The Aussies who land on the multi-entry Business question are a specific shape. They're not leisure travellers. They're consultants flying Sydney to Phnom Penh every six weeks for a regional client. They're supply-chain managers from Melbourne doing quarterly factory walk-throughs across Kampong Speu and Bavet. They're regional sales leaders running Cambodia plus Vietnam plus Thailand from a Brisbane home base, with Cambodia as one stop on a five-country loop they fly twice a quarter.

For all of them, single-entry visas — even at the comfortable $90 USD (~$137 AUD) Business price — start feeling like the wrong shape after the third or fourth trip in twelve months. Three business days of processing per trip, a fresh application form per trip, a fresh PDF to print and carry per trip. Multi-entry collapses that whole cycle into one application, one approval, and one document that works for either 6 or 12 months of as-many-trips-as-you-need.

This guide walks through the rules in detail — who it's for, how to apply (we add it as an option at checkout), what it costs, and importantly when single-entry Business is more economical. If you haven't sorted the base visa yet, the Cambodia Business visa for Australians guide is the right anchor, and the Cambodia eVisa application page is where the multi-entry option lives at checkout. Our Cambodia eVisa for Australian travellers pulls all the pieces — cost, documents, processing — into one place.

The five rules of the multi-entry Business eVisa

There are five core rules that define how the multi-entry Business eVisa works for Australians. Get all five straight before you decide, because each one rules a different group of travellers in or out.

Rule 1 — Business class only

Multi-entry is offered only on the Business eVisa (E-Class). The Tourist eVisa (T-Class) at $80 USD (~$122 AUD) is single-entry by design and cannot be upgraded to multi-entry through any path. If your trip purpose is leisure-only and your year holds one or two short trips, the Tourist class is correct and multi-entry is the wrong question. The Business class supports meetings, supplier visits, due-diligence, conferences, sales calls, long stays, and sponsored events — and crucially, it's the only class that hosts the multi-entry option.

Rule 2 — Two validity windows

Multi-entry runs in either a 6-month or a 12-month validity window from the date of issue. Inside that window you can enter and exit Cambodia as many times as you like — there is no per-year or per-quarter cap on entry count. Outside the window, the visa is dead, regardless of how many entries you used. The 6-month option suits a single quarterly project or one supplier-visit cycle; the 12-month option suits a year-round regional role with monthly flights.

Rule 3 — Each stay capped at 30 days

Every individual stay inside Cambodia is capped at 30 days. You arrive on day one, the clock starts, and you must exit before day 30. Once you've left the country, you can fly back in immediately or at any later point within the validity window — and a fresh 30-day stay clock starts on each re-entry. The multi-entry visa is not a long-stay product; it's a many-short-stays product. If a single visit will run beyond 30 days, multi-entry is the wrong product and you should be looking at a Business eVisa plus an in-country extension instead.

Rule 4 — Roughly $200-220 USD (~$305-336 AUD) all-in

The total cost lands at roughly $200-220 USD (~$305-336 AUD) per traveller for the multi-entry Business eVisa. That includes the $150 USD multi-entry component itself plus our service component on top of the standard Business eVisa baseline. The fee is paid once at application; there are no per-entry fees on top, no annual renewals inside the validity window, and no surcharge for picking 12 months instead of 6 months (both options sit in the same price band).

Rule 5 — Approved in 3 business days, same as standard Business

Processing is the same as any other Cambodia eVisa: approved in 3 business days, delivered as a printable PDF by email. The multi-entry flag is added at checkout on the standard Business eVisa application — there is no separate form, no separate document submission, and no separate approval queue. Your single PDF reaches Immigration with the multi-entry endorsement on it, and that's what gets scanned at every entry across the validity window.

Who the multi-entry Business eVisa is actually for (the Aussie shortlist)

Multi-entry is not a default product. It is the right product for a narrow set of Aussie travellers whose year has a specific shape — monthly or near-monthly flights into Cambodia, each trip short, across either a half-year or a full-year window. Three profiles dominate the multi-entry desk.

Profile 1 — The fly-in-monthly consultant

Sydney or Melbourne management consultant on a regional engagement that lands them in Phnom Penh once every four to six weeks. Each trip runs four to eight working days. Across a 9-month engagement they'll do 8-10 Cambodia entries. The 12-month multi-entry Business eVisa at $200-220 USD (~$305-336 AUD) all-in is unambiguously the right product — versus 10 single-entry Business eVisas at $90 USD each, which is $900 USD (~$1,371 AUD), the multi-entry saves roughly $680-700 USD (~$1,036-1,066 AUD) over the engagement and removes nine separate eVisa applications from the workflow.

Profile 2 — The supplier-visit traveller

Brisbane or Perth supply-chain manager running quarterly factory walk-throughs in Cambodia plus the broader regional cycle. Cambodia gets visited four to six times a year, each visit two to five days. The 6-month multi-entry option suits if the supplier-visit cycle is concentrated into one half of the year; the 12-month option suits if visits are spread evenly across the calendar. Either way, the multi-entry product collapses what would otherwise be six separate Business eVisa applications into one.

Profile 3 — The regional sales leader

Regional sales role covering Cambodia plus Vietnam plus Thailand plus Singapore, with Cambodia as one stop on a multi-country loop the traveller runs once or twice a quarter. Eight to twelve Cambodia entries a year. The 12-month multi-entry Business eVisa is the clean answer. For travellers in this profile the Cambodia frequent-traveller visa strategy guide for Australians is worth reading alongside this one — it covers the broader pattern-matching across visa class and extension options.

How to apply (we add multi-entry as a checkout option)

The application flow is the standard Cambodia Business eVisa flow with one extra option at checkout. There is no separate multi-entry application form, no separate document upload, and no separate approval queue. The four steps below cover the whole sequence end-to-end.

Step one — start the Cambodia eVisa application as you would for any standard Business eVisa. You'll need your Australian passport bio-scan (clean, edge-to-edge, no shadow), a recent passport-style colour photo on a plain background, and the standard Business eVisa fields (purpose of visit, intended entry port, expected dates). Same requirements as a single-entry Business eVisa application.

Step two — at the checkout stage, select the multi-entry option. You'll see the two validity windows (6 months or 12 months from issue date) and the total cost (~$200-220 USD / ~$305-336 AUD) shown alongside the single-entry Business eVisa total ($90 USD / ~$137 AUD). Pick the window length that matches your projected engagement or supplier-visit cycle.

Step three — pay using the standard checkout (card, Apple Pay, Google Pay, or PayPal). The application enters the same 3 business day processing queue as a standard Business eVisa. There is no rush option, no priority lane, and no shortcut — three business days is the standard window for every eVisa class.

Step four — receive your approval as a printable PDF by email, with the multi-entry endorsement printed on it. Print two copies (one for the carry-on, one as backup), and you're set for the full validity window. If Immigration flags a correction on the way through, the free resubmission policy applies the same way it does on any eVisa, with Aussie-timezone support across the resubmission. The Cambodia eVisa documents required for Australians guide covers the document specs in full.

When single-entry Business eVisa is the more economical call

Multi-entry is not the right answer for everyone in the Business class. There are clear shapes of year where the simpler single-entry Business eVisa at $90 USD (~$137 AUD) per trip is the cheaper option, and it's worth being honest about where the break-even sits.

One Cambodia business trip in the year — single-entry Business at $90 USD (~$137 AUD) is unambiguously cheaper than multi-entry at $200-220 USD. You'd be paying $110-130 USD (~$168-198 AUD) for re-entry permission you'll never use.

Two Cambodia business trips in the year — single-entry at $90 USD each is $180 USD (~$274 AUD), still cheaper than multi-entry. Even at two trips, the multi-entry premium is $20-40 USD (~$31-62 AUD) of overpay for convenience that two short trips don't really need.

Three Cambodia business trips in the year — break-even territory. Three single-entry Business eVisas is $270 USD (~$411 AUD), versus multi-entry at $200-220 USD. Multi-entry pulls clear by $50-70 USD (~$76-107 AUD) on cost, plus saves the time of two extra applications.

Four or more Cambodia business trips in the year — multi-entry wins comfortably. Four single-entry Business eVisas is $360 USD (~$548 AUD), six is $540 USD (~$823 AUD), eight is $720 USD (~$1,096 AUD). The multi-entry total stays at $200-220 USD regardless. The savings scale linearly with trip count.

One important caveat — multi-entry is only the right call if every individual trip will stay under 30 days. If even one trip in the year is going to run past 30 days, you need a Business eVisa plus an in-country extension instead, and multi-entry doesn't help with that. The Cambodia 12-month visa extension guide for Australians covers the long-stay path.

Pulling the multi-entry decision together for 2026

Short version for Aussies on the Business eVisa side of the house: multi-entry is a Business-only product at roughly $200-220 USD (~$305-336 AUD) all-in, valid 6 or 12 months, with each stay capped at 30 days and unlimited entries inside the validity window. It's the right product for four-plus Cambodia entries a year, break-even at three, and overkill at one or two. The Cambodia eVisa multiple entry guide for Australians covers the broader multi-entry landscape if you want the full picture.

If you're ready to apply, multi-entry is selected at checkout on the standard Business eVisa application — 3 business days, printable PDF by email, free resubmission if Immigration flags a correction. The Cambodia visa cost guide for Australians has line-by-line pricing across every class, and the Cambodia first-trip planning checklist for Australians is worth a look if this is your first Cambodia trip on the Business class rather than a returning engagement.
