Cambodia Business Visa for Australians: 2026 E-Class Guide (Meetings, Work, Long Stays)

Tourist eVisa vs Business eVisa: the honest side-by-side

Here is the honest comparison for Australians choosing between the two routes in 2026. The fields that matter to a business trip are the bottom three — extendable in-country, best for, and not suitable for.

When Tourist isn't enough — three Aussie scenarios

Scenario one: a Sydney consultant flies into Phnom Penh for what she calls a holiday, but spends three afternoons in client meetings on her firm's behalf. Cambodian Immigration treats that as business travel. The Tourist eVisa technically does not cover it, and a candid answer to the officer at the desk — "I'm here for two meetings and then a few days at Angkor" — gets her flagged. The Business eVisa is the clean route. Same price difference as a cup of airport coffee.

Scenario two: a Brisbane software engineer is working remotely for an Australian employer while based in Siem Reap for six weeks. The trip is leisure in shape, but the work is paid and the stay is over 30 days. The Tourist eVisa caps at 30 days with no extension since November 2025 — there is no legal path to stay longer on that visa. The Business eVisa, with a 1-month extension lodged in-country, is the correct and only route.

Scenario three: a Perth retiree couple are spending three months in Kampot trialling life there before deciding whether to relocate. No paid work, no meetings, no business contacts — but the stay is 90 days. Same answer. The Tourist eVisa cannot stretch beyond 30 days. The Business eVisa, with a 3-month extension, fits the trip cleanly.

In-country extensions: how the Business eVisa keeps working

The single biggest reason the Business eVisa exists for Australians in 2026 is the extension. The Tourist eVisa is a hard 30 days. The Business eVisa lets you stay another 1, 3, 6, or 12 months on top of the initial 30 — and the extension is lodged inside Cambodia, with a Cambodian immigration agent, while you are already in the country. It is the only visa that supports this. Our Australian application walkthrough covers the upfront online form; the extension flow comes later, on the ground.

Documents required (and what is NOT required)

The Cambodia Business eVisa application asks for the same short pack as the Tourist. Five items, all of which most Aussies already have on hand. Roughly ten minutes online if your passport and a fresh photo are ready on the same device.

• Australian passport — at least 6 months validity from your planned date of arrival in Cambodia, with at least one full blank page for the entry stamp.
• Digital passport-style photo — 4×6 cm, plain white background, taken in the last 6 months, no glasses, no hats, no smile, neutral expression. JPEG, under 2 MB.
• Clear scan or phone photo of your passport bio page — both edges visible, no glare on the laminate, all text legible.
• Working email address — the approval PDF lands here.
• Payment method — Visa, Mastercard, AmEx, PayPal, Apple Pay or Google Pay. AUD equivalent shown on your card statement.

Now the unusual part. The Cambodia Business eVisa is one of the few regional business visas that requires zero corporate documentation at the application stage. No sponsor letter from a Cambodian company. No employment contract. No formal invitation. No return flight ticket. No hotel booking. No bank statement. Compared with the Vietnam DN visa, the Thailand B visa, or the Indonesia C312, this is a remarkably light pack. Our Cambodia eVisa documents required guide for Australians lays out the full document set in detail.

That doesn't mean Immigration won't ask casual questions at the airport about the purpose of your visit — they sometimes do. But the application itself sticks to the basics. If you can complete a Tourist eVisa, you can complete a Business one. The price step from $80 USD (~$122 AUD) to $90 USD (~$137 AUD) is a $10 USD difference for a visa class that opens up a fundamentally different trip.

How extensions work in-country

Once you are in Cambodia on the Business eVisa, extensions are arranged through a Cambodian immigration agent — not directly with the General Department of Immigration. Most Aussies use an agent based in Phnom Penh or Siem Reap; the agent takes your passport, lodges the extension paperwork, and returns it stamped a week or two later.

Four extension lengths are available: 1 month, 3 months, 6 months, and 12 months. All four are renewable — you can stack a 6-month extension on top of an earlier 6-month one, for example, and run a full year in-country on the same original Business eVisa. The 12-month extension is multi-entry, which matters if you plan to slip out to Bangkok or Singapore midway.

Indicative agent fees are a moving target — Cambodian agent pricing fluctuates with demand and with the riel-dollar rate — so we don't quote exact AUD figures here. As a working ballpark in 2026, expect the 1-month extension to be the cheapest per-month rate to start but a poor value for stays longer than a few weeks. The 3-month and 6-month extensions tend to be the sweet spots: the per-month rate drops sharply, and most Aussies on extended business trips or digital-nomad stays land in one of those two buckets. The 12-month extension is the best value per month for genuine long-stayers and retirees.

Process time is typically 7 to 14 days for the agent to return your stamped passport. Recommendation: start the extension paperwork at least 2 weeks before your initial 30-day stay expires. Cutting it closer than that puts you at risk of overstay — the Cambodian overstay penalty is $10 USD per day from day one, payable in cash at the airport on exit, and an overstay over a few weeks long can affect future visa applications.

Common Aussie use cases mapped to extension length

Choosing the right extension length up front saves money and a second trip to the agent. Here is the working map we use with Australian travellers, based on the trips we see most often.

• 1 month — short consulting gigs, extended due diligence, or an executive who needs a few extra weeks past the initial 30 days to wrap up a contract or close a deal.
• 3 months — a quarterly assignment, a single-project contract for an Aussie freelancer, or a structured business development trip with multiple supplier visits. One of the two sweet-spot rates.
• 6 months — digital-nomad seasonal stays (the classic dry-season Aussie in Siem Reap), longer contract work for an Australian employer with a Phnom Penh client, or a sabbatical. The other sweet-spot rate, and the most common pick among Aussie remote workers we process.
• 12 months — long-term contract work, retirement reconnaissance (an Aussie couple trialling a full year in Kampot or Kep before deciding to stay), or any Aussie with a genuine multi-year plan in Cambodia who wants the multi-entry flexibility for trips home and to Singapore or Bangkok.

The honest framing on cost: the 3-month and 6-month extensions deliver the best Australian-dollar value per month of stay. The 1-month is convenient but expensive per day; the 12-month is the cheapest per day but only makes sense if you genuinely plan to use most of it.

Border presentation and arrival in Cambodia

Arrival on the Business eVisa is identical to arrival on the Tourist. Print two A4 copies of the Business eVisa approval PDF — one for entry, one for exit. Carry your Australian passport with at least 6 months validity. Have your e-Arrival QR code saved to your phone, screenshot for offline access.

Open airports for Aussie arrivals are KTI (Phnom Penh — the new Techo International Airport), SAI (Siem Reap), and KOS (Sihanoukville). Land entry is realistic only from Vietnam at Bavet, or from Laos at Tropaeng Kreal — all seven Thailand–Cambodia land borders have been closed since June 2025.

The immigration officer may ask the purpose of your visit. Answer honestly — "business meetings," "client visit," "sponsored conference," or "remote work for an Australian employer" are all standard answers. There is no trick question here, and the Business eVisa is the visa that explicitly authorises those activities. Queue time is typically 10–20 minutes through the manual desk, faster through the e-gate. The Cambodia visa processing time from Australia guide covers the timing side end-to-end, and the Smartraveller advisory is the official Australian government view.
