Cambodia Multiple-Entry Visa for Australians: 2026 Guide (When You Need It, How to Get It)

The maths: 3 worked Aussie scenarios

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 fresh-Tourist-eVisa alternative (and when it's legitimately better)

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.

How to actually arrange a multi-entry extension

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.

Edge case: lost or stolen visa during a multi-entry trip

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.

Pulling it together for your 2026 Cambodia multi-entry decision

Short version for Aussies: the eVisa portal issues single-entry only, multi-entry lives on the in-country Business extension, the premium is $30–50 USD on top of the base extension fee, and for one or two short hops out the repeat-Tourist-eVisa approach is often cleaner. Pick the path that matches the shape of your trip. The Vietnam-Cambodia visa combo guide is worth a look if you're combining the two — it's the most common multi-entry scenario for Australians in 2026.

If you still need the underlying paperwork sorted, the Australian application walkthrough covers every field in the upfront eVisa flow, the Do Australians Need a Visa for Cambodia pillar covers eligibility, and the Thailand-Cambodia border closure update is the context for why the multi-entry question is louder this year than last. Three business days, $80 USD (~$122 AUD) all-in Tourist or $90 USD (~$137 AUD) Business, and you can sort the multi-entry upgrade in-country once you're settled.
