Perjalanan Ketiga Anda ke Kamboja Tahun Ini: Kapan eVisa Wisata Tidak Lagi Masuk Akal untuk Orang Australia

The time arithmetic Aussies underestimate

Money is the obvious axis; time is the one Aussies on trip three quietly underestimate. Each Tourist eVisa application is a fresh form, a fresh payment, a fresh 3-business-day waiting cycle, and a fresh moment of remembering to print the PDF before you fly. Three of those is three separate weeks of low-grade admin spread across the year. By contrast, one Business eVisa plus a single in-country extension visit is one upfront cycle and then nothing for six or twelve months.

Run the numbers honestly. A Tourist eVisa form takes around 15-20 minutes from start to submit if you have your passport scan and photo ready. Add another 10-15 minutes the day before each flight to print the PDF, check the details, and stash it in the booking folder. Across three trips that's roughly 75-105 minutes of pure admin, spread as small interruptions across the year. Across four trips it's closer to two hours. The Business + extension stack is a single 20-minute form upfront, plus one half-hour visit to an immigration agent in Phnom Penh or Siem Reap once you arrive on trip one. After that, nothing — you walk up to Immigration on each re-entry, the multi-entry stamp does the talking.

The Cambodia eVisa desktop application walkthrough for Australians has timing benchmarks across the form if you want to sanity-check how long each fresh application would actually take you. Most Aussies on their third application know the form by heart by then — but the cycle time is the same regardless of familiarity.

The forcing factors that make trip three an obvious Business call

Cost and time aside, there are three trip-shape factors that turn the trip-three decision from 'lean Business' into 'obviously Business' for Aussies. If any one of these is true of your year, stop reading and switch tracks now.

Forcing factor 1: any single trip might exceed 30 days

Since November 2025, the Tourist eVisa cannot be extended in-country, full stop. The auto-extension that used to apply at airports has ended. If trip three, trip four, or trip five could plausibly land at 35, 45, or 60 days because work or family pulls you into a longer stay, the Tourist eVisa is structurally wrong for that trip and you're forced onto Business anyway. Do it now and the question is settled for the year.

Forcing factor 2: you have a 6-week window where two trips back-to-back are likely

Tourist eVisas are single-entry. If you fly out of Cambodia to Bangkok or Singapore for a meeting and want to fly back in a week later, you need a fresh Tourist eVisa for the re-entry — another $80 USD (~$122 AUD) and another 3-business-day cycle. Aussies who do regional hopping during a longer stretch in Cambodia routinely get caught by this. Business with multi-entry collapses it to a single walk-up at Immigration.

Forcing factor 3: any of the trips are work-related

Even if your trips are largely leisure, if any of them involve meetings, paid work, conferences, supplier visits, sales calls, due-diligence, or sponsored events, the right product was Business eVisa from the start. The Business eVisa positioning guide walks through the activity scope. The Tourist class is for tourism — not a hard ban on incidental work, but the wrong product if the trip's centre of gravity is professional.

How the switch from Tourist to Business actually works on trip three

The mechanics of switching are simpler than most Aussies expect. There's no special transfer flow, no record you need to update with MFAIC, no concession to lose by abandoning the Tourist class mid-year. You just lodge the next application as a Business eVisa and the system processes it like any other Business application. The two prior Tourist eVisas you used are closed entries on Cambodia's side — they don't compound, don't carry over, and don't generate friction at Immigration when you arrive on the Business eVisa.

The application itself is the standard Cambodia Business eVisa form, $90 USD (~$137 AUD) all-in, approved in 3 business days, delivered as a printable PDF by email. The only meaningful difference from your prior Tourist applications is the visa-type selector at the top of the form. Once you arrive in Cambodia on this Business eVisa, you have two paths. Path one: this is a normal-length trip under 30 days, you skip the in-country extension entirely, and you upgrade to multi-entry only when you have a clear sense of how many more trips are coming. Path two: you know you'll be coming back, so you visit a vetted immigration agent in Phnom Penh or Siem Reap during the first trip and lodge the 6-month or 12-month multi-entry extension upfront.

The Cambodia visa extension agents in Phnom Penh guide for Australians has a vetted shortlist and the questions to ask before handing over your passport. The Cambodia multi-entry guide for Australians covers the difference between 6-month and 12-month options and which one Aussies on a four-trip cadence usually pick.

When trip three is genuinely the right place to stop on Tourist

There is a clean case for finishing the year on the third Tourist eVisa rather than switching, and a small number of Aussies on the desk land in it honestly. The shape is specific: you have done two short trips already this year, trip three is a known endpoint (a family event, a final loop, a planned-final visit), no trip on the horizon exceeds 30 days, no trip is work-related, and you have realistic confidence that you will not return to Cambodia inside the next six months.

If all five of those are true, three Tourist eVisas at $240 USD (~$366 AUD) total is the cheaper and simpler outcome, full stop. You don't need the multi-entry premium, you don't need the in-country extension visit, you don't need a Business class you won't use. Buy the third Tourist eVisa, print the PDF, fly out, file the year. Where this gets you in trouble is if any of those five conditions are aspirational rather than real. Most three-trip Aussie travellers come back for a fourth — work pivots, family lands, a cheap flight pops up — and the trip-four moment is when the Tourist-only strategy starts costing money rather than saving it.

If your honest answer is 'probably no fourth trip but maybe', the lowest-regret path is still to switch to Business on trip three and skip the multi-entry extension. Business eVisa $90 USD (~$137 AUD) versus Tourist eVisa $80 USD (~$122 AUD) is a $10 USD (~$15 AUD) premium that buys you optionality for the rest of the year. The Cambodia frequent-traveller strategy guide for Australians has the longer-horizon decision tree if your cadence is starting to look more like a pattern than a coincidence.

Pulling the trip-three decision together

The short version for Aussies on trip three: if a fourth trip is realistic before December, switch to Business now. If any single trip might exceed 30 days, switch to Business now — the Tourist class is closed to extensions since November 2025. If any of the trips are work-related, you should have been on Business from trip one and now's the moment to fix it. Otherwise, finishing the year on a third Tourist eVisa at $80 USD (~$122 AUD) is a defensible call. The Cambodia visa cost guide for Australians has every fee laid out if you want to pressure-test the numbers against your own plan.

Whichever path you pick, the underlying paperwork is the same shape — 3-business-day approval, delivered as a printable PDF by email, free resubmission if Immigration flags a correction, Aussie-timezone support if anything stalls. The Cambodia eVisa application page is the start of trip three either way.
