Cambodia's eVisa portal issues single-entry only — both Tourist ($80 USD / ~$122 AUD) and Business ($90 USD / ~$137 AUD). Multi-entry is a separate upgrade on an in-country Business extension. Here's the maths and the decision tree for Aussies.

Not directly through the eVisa portal — both the Tourist eVisa ($80 USD / ~$122 AUD) and the Business eVisa ($90 USD / ~$137 AUD) are single-entry only when issued. Multi-entry is available ONLY as an upgrade on an in-country Business eVisa extension (1, 3, 6, or 12 months) processed through a Cambodian immigration agent, with a ~$30–50 USD premium on top of the base extension fee. If you're doing a Cambodia trip with planned side-jaunts to Thailand or Vietnam and back, your two clean options are: (1) enter on the Business eVisa and upgrade to multi-entry when you extend in-country, or (2) just buy a fresh Tourist eVisa each time you re-enter — both totally legitimate, the right answer depends on your trip shape.
Multi-entry into Cambodia used to be a niche question — a handful of NGO staff and consultants asked it, almost no leisure travellers did. That has changed sharply over the last eighteen months. Aussie travel patterns shifted post-pandemic: more multi-country SE Asia loops instead of single-country trips, more remote workers doing month-on/month-off Cambodia + Bangkok rotations, more retirees treating Cambodia as a regional base with weekend hops to Vietnam or Singapore.
The Thailand–Cambodia land border closure in June 2025 piled extra weight on top. With all seven Thai crossings shut, anyone mixing a Cambodia trip with Thailand now has to fly between them — and a flight means a fresh entry stamp, which means thinking about whether your visa supports that. The result is more Aussies arriving at the multi-entry question than at any point in the last decade.
This is the honest guide for Australian travellers in 2026 — when multi-entry is the right answer, when it isn't, and exactly how to arrange it if it is. If you haven't yet sorted the underlying visa, the Cambodia eVisa application is the place to start, and the Australia country pillar covers the wider eligibility picture for permanent residents and dual citizens.
The first thing to understand is the two-stage model. Cambodia does not issue multi-entry visas at the application stage — not on the Tourist eVisa, not on the Business eVisa, not anywhere on the eVisa portal. Every visa issued through the portal is single-entry. That's true whether you pay $80 USD (~$122 AUD) for the Tourist class or $90 USD (~$137 AUD) for the Business class. The original visa is consumed the moment your first entry into Cambodia is stamped.
Multi-entry, when it exists, lives on the in-country extension. You enter Cambodia on a Business eVisa (E-Class), settle in for your initial 30 days, and at the point you extend the visa through a Cambodian immigration agent, you have the option to pay an extra premium — roughly $30–50 USD — to make that extension multi-entry. The multi-entry permission attaches to the extension, not to the original visa. It's a separate paid upgrade lodged at a separate point in the journey.
Three knock-on consequences. First, the Tourist eVisa can never be multi-entry because the Tourist class has had no in-country extension path since November 2025 — no extension to attach the upgrade to. Second, the original Business eVisa entry stamp is also single-entry by definition, so a re-entry within the initial 30 days still needs a fresh eVisa. Third, the multi-entry permission lasts for the duration of the extension only — when the extension expires, so does the multi-entry permission.

If your trip involves one or maybe two re-entries into Cambodia and you're not staying long enough to need an extension anyway, the answer is almost always just buy a fresh Tourist eVisa per re-entry. Each eVisa is $80 USD (~$122 AUD), approved in 3 business days, delivered as a printable PDF by email. Two of them is $160 USD. That undercuts the Business eVisa plus multi-entry extension route for any trip shape that wouldn't have needed an extension in the first place.
The cleanest case is a short leisure trip with a weekend out — a 21-day Phnom Penh and Siem Reap loop with a Bangkok long weekend in the middle, for example. The single-entry approach also keeps you on the Tourist class throughout, which is the simpler product and the one most Aussie leisure travellers should default to.
On the other side, multi-entry Business extension is the obvious answer the moment your trip ticks two boxes: you're staying more than 30 days (so you need a Business extension anyway), and you'll be in and out of Cambodia more than once during that extension. Digital nomads doing a 6-month season with monthly weekends in Bangkok or Vietnam, consultants on a quarterly engagement with regular flights home, retirees doing a 12-month trial with trips back to Australia — these are the textbook cases. The Cambodia Business visa extensions guide for Australians has the full mechanics on the underlying extension flow.

Worked examples are the fastest way to see which option wins. The three below are the most common Aussie patterns we see on the multi-entry desk. Numbers are 2026 indicative — Tourist eVisa $80 USD (~$122 AUD) all-in, Business eVisa $90 USD (~$137 AUD), and extension fees at mid-range Phnom Penh agent quotes.
Scenario one — Sydney consultant, 60-day Phnom Penh project with one Bangkok weekend in the middle. Option A: enter on a Tourist eVisa, fly to Bangkok in week six, re-enter on a fresh Tourist eVisa for the back end of the project. Total: 2 × $80 USD = $160 USD (~$244 AUD). Option B: enter on a Business eVisa, take a 1-month multi-entry extension when the initial 30 days run out. Total: $90 USD initial + $80–130 USD extension with multi-entry premium = $170–220 USD (~$259–335 AUD). Option A wins for this shape, by a meaningful margin. The Tourist class is also the simpler product and matches the trip purpose if the work is short consulting rather than a long-stay engagement.
Scenario two — Melbourne digital nomad, 6-month season in Siem Reap with four weekend trips to Bangkok or Vietnam. Option A: 5 × Tourist eVisas (the initial one plus four re-entries) = $400 USD (~$609 AUD). Option B: Business eVisa + 6-month multi-entry extension = $90 USD initial + $210–290 USD extension-with-multi = $300–380 USD (~$457–579 AUD). Multi-entry extension wins clearly, both on cost and on convenience — you're not refiling four separate eVisa applications and waiting 3 business days each time. The Business class also handles the digital nomad use case more honestly than the Tourist class does.
Scenario three — Brisbane retiree on a 12-month Cambodia trial with quarterly trips home to see grandchildren. Option A: 5 × Tourist eVisas = $400 USD (~$609 AUD). Option B: Business eVisa + 12-month multi-entry extension = $90 USD initial + $330–450 USD extension-with-multi = $420–540 USD (~$640–823 AUD). Roughly break-even on cost — pick based on convenience. The single visa-plus-extension stack means one trip to the agent and then twelve months of frictionless re-entry, which most retirees prefer over filing a fresh eVisa four times across the year.
Two patterns jump out from the three scenarios. First, for short trips with one re-entry the Tourist eVisa repeat is almost always cheaper and simpler. Second, for stays of more than 90 days with regular outs, the multi-entry Business extension wins on convenience even when the cost is line-ball. Our 2026 Cambodia visa cost guide for Australians has the line-by-line on all of these options.

The repeat single-entry approach gets dismissed too easily by travellers who assume multi-entry is automatically better. It isn't, and the reasons are worth spelling out. Buying a fresh Tourist eVisa for each re-entry is totally legal, totally common, and the processing time is the same 3 business days no matter how many times you do it. The fee is the same $80 USD (~$122 AUD) each time. The application form is the same. The approval PDF lands in your email the same way.
Three quiet upsides. First, it keeps you on the simpler Tourist class throughout. Second, you never deal with the in-country extension flow — no agent visits, no passport held for 7–14 business days, no $30–50 USD multi-entry premium. Third, your visa permission resets cleanly with each re-entry — no question of whether a multi-entry extension still has time left when an unexpected trip comes up.
The honest downside is the one constraint most Aussies miss until they're already in trouble: you cannot apply for a new Cambodia eVisa while you are still inside Cambodia. The eVisa portal expects you to be applying from outside the country at the time of submission, and the system is checked at entry. So if you're planning the repeat-eVisa route, your between-trip flights need to land you somewhere outside Cambodia for long enough to apply and wait 3 business days — usually that's the destination of your hop out anyway. Plan the in-between leg with that in mind. The Cambodia Tourist visa for Australians guide has the application detail.

If your trip maths points at the multi-entry Business extension, the practical sequence is short. Enter Cambodia on the Business eVisa ($90 USD / ~$137 AUD), settle in for the first 30 days, and start the extension paperwork at least two weeks before that initial stay expires. Walk into an immigration agent in Phnom Penh or Siem Reap with your passport, a recent passport-style photo, your current accommodation address, and USD cash for the extension fee plus the multi-entry premium.
When you sit down with the agent, ask explicitly for multi-entry on the extension length you want — one, three, six, or twelve months. The agent will quote a base extension fee plus the ~$30–50 USD multi-entry premium on top. Pay in full, take a written receipt with the date and the extension length, and the agent will hold your passport while the application is lodged with the General Department of Immigration. Standard turnaround is 7–14 business days, after which the agent returns your passport with the multi-entry extension stamp inside.
One detail Aussies miss: the multi-entry permission starts from the date the extension is issued, not from the date your initial 30 days expire. If you lodge the paperwork two weeks early (which is the right thing to do for safety), the extension stamp's start date will be the day Immigration approves it, not the day your old visa would have run out — but the agent will line up the durations so you don't lose stay-days. Confirm this in writing with the agent before handing over cash. The Cambodia Business visa for Australians anchor has the upfront-application detail if you haven't yet booked the underlying visa.

The multi-entry extension lives inside your passport as a physical stamp. That makes the lost-or-stolen-passport scenario more painful than it is for a fresh eVisa, where the approval is just a PDF sitting in your email and can be reprinted at any internet café. If your passport with the multi-entry stamp is lost while you are outside Cambodia — say, on a weekend in Bangkok or a Vietnam beach trip — you go through the Cambodian embassy in your transit country for a replacement entry document, or you fly home to Australia and re-apply for a fresh Business eVisa once a new passport is issued.
If the loss happens while you are still inside Cambodia, the path is the General Department of Immigration in Phnom Penh. You'll need a police report from the local station where the passport went missing, a passport-style photo, and your Australian embassy correspondence confirming a replacement passport is on the way. Immigration's job at that point is to reissue the multi-entry stamp into your new passport, not to make you reapply for the extension from scratch — though the paperwork and the fees vary case to case.
Either way, we can support remotely. The multi-entry desk holds copies of your original visa approval and your extension receipt, both of which are useful pieces of evidence at the embassy or at Immigration. The Smartraveller advisory is the right first call from an Australian government standpoint — they coordinate emergency passports through the Australian embassy network across the region. Our Cambodia eVisa vs Visa on Arrival comparison covers the broader picture of how Cambodia's entry stamping works if your trip ends up needing a fresh entry stamp.
