Cambodia Overstay Fines & Airport Recovery for Australians: 2026 Guide
The 2026 Cambodia overstay fine is $10 USD (~$15.20 AUD) per day for up to 30 days overstay, paid in USD cash at the KTI, SAI, or KOS departure desk before boarding. Calm, cash-ready, and brief — that's the whole airport conversation. Honest guide to handling the desk, the beyond-30 risk, and how an overstay flags your next eVisa application.
What happens if an Aussie overstays their Cambodia visa in 2026?
If you overstay your 30-day Cambodia stay by up to 30 days, you pay an overstay fine of $10 USD (~$15.20 AUD) per day in USD cash at the departure desk at KTI Phnom Penh, SAI Siem Reap, or KOS Sihanoukville before boarding. Calm, cash ready, brief conversation — the desk staff are used to it. Beyond 30 days overstay is a different situation: formal detention becomes possible, embassy involvement becomes likely, and a fine alone cannot resolve it. The overstay is logged in the Cambodian Immigration database and may trigger a manual review on your next eVisa application. The clean way to avoid the whole situation is an in-country Business eVisa extension before day 30, or a Tourist eVisa visit kept honestly to 30 days.
Wichtigste Erkenntnisse
- The 2026 Cambodia overstay fine is $10 USD (~$15.20 AUD) per day for up to 30 days overstay, paid in USD cash at the departure desk before boarding.
- Beyond 30 days overstay shifts the conversation — formal detention is possible, embassy involvement becomes likely, and a fine cannot resolve it at the desk alone.
- The airport handle is calm and short: have the right USD cash in hand, hand it over with your passport, accept the receipt, board the flight. No negotiation required.
- An overstay is noted in the Cambodian Immigration database (MFAIC) and triggers a manual review on your next eVisa application — usually a one-day delay, not a refusal.
- The cleanest way to avoid the situation entirely is an in-country Business eVisa extension before day 30 — $50 USD (~$76 AUD) for a 1-month extension via a Phnom Penh agent.
Why this matters for Aussie travellers in 2026
Overstay happens for ordinary reasons. A flight gets cancelled and the next available seat is three days later. A bout of food poisoning in Kampot pushes a planned departure back a week. A wedding invitation in Battambang lands while you are already in-country and there is no clean way to leave and return inside the existing visa. A simple counting mistake — the 30-day stay runs from your entry date, not the visa issue date, and travellers occasionally lose track. None of these are dramatic, and Cambodian Immigration treats short overstays as a paperwork question rather than an enforcement issue.
The information online about how the overstay process actually works at the airport is patchy — old forum posts quoting outdated fine rates, defensive blog content, or panicked traveller-forum threads that have already aged out of relevance. The 2026 operating reality is calmer than most of that suggests. The fine schedule is published, the airport handle is consistent across the three international airports, and the Aussie traveller's job is essentially to have the right USD cash in hand, stay calm, and not over-complicate the conversation. This guide walks through that handle honestly, including what shifts past the 30-day mark.
The 2026 overstay fine schedule at a glance
The Cambodian Ministry of Foreign Affairs and the General Department of Immigration publish a single flat-rate overstay fine for short overstays — $10 USD (~$15.20 AUD) per day, paid in USD cash at the departure desk on exit. The rate is the same regardless of whether you arrived on a Tourist eVisa (T-Class) or a Business eVisa (E-Class), and whether your overstay was three days or twenty-five. There is no escalator inside the first 30 days. Past 30 days the framework changes substantially, and the fine on its own no longer settles the situation at the desk.
Why the airport handles short overstays cleanly
Short overstay is an everyday occurrence at KTI, SAI, and KOS — the desk staff process it as routine. There is no separate counter, no formal interview room, no enforcement officer escort for travellers paying a 7-day or 14-day overstay fine. You join the departure immigration queue with everyone else, the officer notices the date gap when they scan your passport, and they hand you off to the overstay desk a few metres away. You hand over USD cash, the staff member counts it twice, prints a small receipt, stamps your passport with the exit stamp, and you walk through to airside. The conversation is short by design — most short-overstay processings take under 10 minutes from when you join the queue.
Häufig gestellte Fragen
What is the 2026 Cambodia overstay fine for Australians?
$10 USD (~$15.20 AUD) per day, flat, for overstays of 1 to 30 days. Paid in USD cash at the departure desk at KTI Phnom Penh, SAI Siem Reap, or KOS Sihanoukville before boarding. The rate is the same regardless of whether you arrived on a Tourist eVisa or a Business eVisa. A 7-day overstay is $70 USD (~$107 AUD), a 14-day overstay is $140 USD (~$213 AUD), a 21-day overstay is $210 USD (~$320 AUD). The day-30 cap on the airport-only handle is $300 USD (~$457 AUD).
Can I pay the overstay fine in AUD or with a card?
No. The overstay fine is paid in USD cash, period. There is no card terminal at the overstay desk, no QR code payment, no fallback to KHR (Cambodian riel) for the fine itself. Bring crisp clean USD notes — older or torn bills are sometimes refused. The cleanest setup is the expected total in a small envelope plus a $50–100 USD (~$76–152 AUD) buffer in case the day count includes the day of departure. ATMs inside KTI, SAI, and KOS dispense USD on most cards, but the cash should be in hand before you reach the immigration desk.
How long does the airport overstay conversation actually take?
Under 10 minutes for most short overstays. You join the departure immigration queue with everyone else, the officer notices the date gap, hands you to the overstay desk a few metres away, you hand over USD cash, the staff member counts it twice, prints a receipt, stamps your passport, and you walk through to airside. The desk staff process dozens of short overstays a day — it is routine, not punitive. Calm, cash ready, brief is the whole handle.
What happens if I overstay by more than 30 days?
The framework changes substantially. The flat $10 USD (~$15.20 AUD) per day fine no longer resolves the situation at the departure desk on its own. Formal detention becomes possible, embassy involvement becomes likely, and the resolution typically takes multiple business days rather than a same-day flight. The Australian Embassy in Phnom Penh recommends consular contact at the first sign of a long-overstay situation. For long overstays, contact a registered Cambodian immigration lawyer through the Embassy referral list rather than trying to handle it at the airport on your own.
Will an overstay stop me getting a Cambodia visa next time?
Usually no — a single short overstay paid cleanly at the desk is treated as a routine record in the Cambodian Immigration database and triggers a manual review on your next eVisa application, typically a one-business-day delay on top of the standard 3-business-day processing. Refusal is uncommon for a single short overstay. Repeat overstays across multiple trips, or any beyond-30-day event, draw heavier review and longer processing times. Through us, flagged applications still come back with full transparency on timeline and Aussie-timezone support across the application window.
