Cambodia 180-Day Business Visa Extension for Australians: The 6-Month Tier for Consultants on Rolling Work
The 180-day extension is the per-month value tier for Aussie consultants running 6-month engagements out of Phnom Penh. Direct at the MFAIC counter it costs $100–150 USD (~$152–229 AUD); through a Phnom Penh agent it lands at $170–200 USD (~$259–305 AUD). The multi-entry add-on is roughly $50 USD (~$76 AUD) on top, and the tier can be renewed once at 180 days for another 180.
How does the 180-day Cambodia Business visa extension work for Australian consultants on rolling project work?
The 180-day extension is the 6-month tier of the Cambodia Business eVisa extension ladder, and for Aussie consultants on rolling engagements out of Phnom Penh it is the sweet spot on cost-per-month. Direct at the MFAIC counter the lodgement fee is $100–150 USD (~$152–229 AUD); through a registered Phnom Penh agent it lands at $170–200 USD (~$259–305 AUD) all-in once the service margin is added. Documents are your passport, your current Business eVisa, a recent passport-style photo, an employer letter if your project is sponsored, and payment in clean US cash. Adding the multi-entry option is roughly $50 USD (~$76 AUD) extra and is worth it the moment any out-and-back trip is on the cards. The tier is renewable once for a further 180 days in-country, so a 6-month extension stacked on a 6-month renewal plus the original 30 days gives you close to 13 months of legal stay on a single original visa.
نکات کلیدی
- The 180-day (6-month) extension is the lowest per-month cost on the Cambodia Business eVisa for stays under a year — cheaper per month than stacking shorter extensions.
- Lodged direct at the MFAIC counter in Phnom Penh, the 180-day extension fee is $100–150 USD (~$152–229 AUD), cash on lodgement.
- Routed through a registered Phnom Penh agent the same extension lands at $170–200 USD (~$259–305 AUD) all-in — a service margin of $50–70 USD (~$76–107 AUD) buys you the trip handling and the agent paperwork.
- The multi-entry add-on is roughly $50 USD (~$76 AUD) extra and pays for itself on the first re-entry — the alternative is buying a fresh Business eVisa at $90 USD (~$137 AUD).
- The 180-day tier is renewable once for another 180 days in-country, giving Aussie consultants close to 13 months of legal stay on a single original Business eVisa.

Why the per-month maths makes 180 days the value tier
Documents Aussie consultants need to lodge the 180-day
- Your Australian passport — physical, signed, with at least 6 months of validity beyond the 180-day extension end date. If your passport expires inside that window, renew with DFAT first.
- Your current Cambodia Business eVisa — the printed PDF you arrived on, with the entry stamp from Phnom Penh airport (KTI) clearly visible.
- One recent passport-style photo — 4cm × 6cm, plain white background, taken in the last six months, head and shoulders only.
- An employer or sponsor letter if your project is sponsored — short single-page letter on letterhead from the Cambodian or international entity engaging you, confirming the engagement, dates, and your role. Not always asked for, but routinely accepted when offered, and it smooths edge-case questions.
- Payment — clean US cash for the MFAIC route ($100–150 USD or ~$152–229 AUD), or per the agent's preferred method (cash is universal, bank transfer is sometimes available).
- A completed extension form — the same bilingual one-pager used for the shorter tiers, available at the MFAIC counter or downloadable from MFAIC.
Sponsor letter template
Half a page, on letterhead, in English. Three sentences: who is engaging you (entity name and address), what the engagement is (a brief description, e.g. 'IT systems implementation advisory'), and the dates and duration (e.g. 'from 1 July 2026 to 31 December 2026'). Signed by an authorised representative with a phone or email contact. That is the whole brief — no need for a multi-page reference letter.
سوالات متداول
How much is the Cambodia 180-day Business visa extension for Australians?
Two prices to know. Direct at the MFAIC counter in Phnom Penh, the lodgement fee for the 180-day extension is $100–150 USD (~$152–229 AUD), paid in clean US cash. Routed through a registered Phnom Penh agent, the same extension lands at $170–200 USD (~$259–305 AUD) all-in — the $50–70 USD (~$76–107 AUD) service margin covers the counter trips and paperwork handling on your behalf. Multi-entry adds roughly $50 USD (~$76 AUD) on top of either route.
Why is the 6-month tier the per-month value sweet spot?
Run the maths. Six stacked 30-day extensions at $50 USD each is $300 USD (~$457 AUD) for 180 days. Two stacked 3-month extensions at $120 USD each is $240 USD (~$366 AUD). The single 180-day extension at the $125 USD midpoint is $125 USD (~$190 AUD) at the counter — less than half the stacked-30s cost for the same legal cover. For Aussie consultants on 6-month engagements, the 180-day tier is the cheapest legal route in-country.
What documents do I need for the 180-day extension?
Your Australian passport with at least 6 months of validity beyond the extension end date, your current Business eVisa printout, a recent 4cm × 6cm passport-style photo on a plain white background, an employer or sponsor letter if your project is sponsored (single page, on letterhead, in English), payment in clean US cash, and a completed bilingual extension form. The sponsor letter is not strictly mandatory but smooths edge-case questions and is worth including if you have one.
How long does the 180-day extension take to process?
At the MFAIC counter: 2 to 3 working days from lodgement to pick-up. Through a Phnom Penh agent: 7 to 10 working days end-to-end, because the agent batches counter trips and adds a paperwork-check step on either side. Lodge at least 2 to 3 weeks before your current Business eVisa expires to keep margin in hand for the upper end of either window. The new extension back-dates to the day after your current visa expires, so there is no gap.
Is multi-entry worth the extra $50 USD (~$76 AUD)?
On a 180-day extension, almost always yes. Without multi-entry, the extension is single-entry, which means exiting Cambodia at any point during the 180 days burns the extension. To re-enter you would need a fresh Business eVisa at $90 USD (~$137 AUD) and a new 30-day clock. The multi-entry premium of roughly $50 USD (~$76 AUD) pays for itself on the first out-and-back trip and saves the new visa hassle. Take multi-entry unless you genuinely will sit in Phnom Penh for the full six months.
