Cambodia VoA Is Cash-Only USD: The Aussie Guide to AUD-to-USD Exchange Before You Fly
Cambodia visa on arrival is cash-only USD — no card terminal at the booth, no friendly ATM beside it. Here's the honest Aussie guide to sourcing $40–$50 USD in clean small notes before you board, and what the AUD-to-USD spread actually costs in 2026.
Why is Cambodia VoA cash-only USD, and how should Australians sort the AUD-to-USD exchange before flying?
Cambodia visa on arrival is cash-only USD at all three airports (KTI, SAI, KOS) because the booth has no card terminal and no ATM directly beside it. Australian dollars are never accepted, and the airport ATM after Immigration dispenses Khmer riel rather than USD. The safest plan for Aussies is to bring $40–$50 USD in clean small notes ($5, $10 and $20 denominations, post-2006, no tears or ink marks) sourced before flying. A pre-ordered bank cash collection from ANZ, CBA, Westpac or NAB sits at roughly 2.5–3.5% over the spot AUD/USD rate in 2026. Travelex and airport currency counters run 5–7% over. With AUD/USD trading around 1.52–1.55 through 2026, a $40 USD VoA budget costs around $61–$65 AUD. The eVisa at $80 USD (~$122 AUD) all-in sidesteps the USD-cash problem entirely.
Poin-Poin Penting

- Spot AUD/USD has traded in a 1.52–1.55 band through the first half of 2026. A $40 USD VoA budget costs around $61–$65 AUD depending on where you buy it.
- The eVisa at $80 USD (~$122 AUD) all-in skips the USD-cash exercise entirely — billed in AUD on your card, approved in 3 business days, delivered as a printable PDF by email.
Why the cash-only rule trips up Aussies in 2026
Every airport in Cambodia bills in US dollars at the visa-on-arrival booth, and every Aussie who turns up without cash discovers the rule the hard way. The booth itself is unforgiving — no card terminal, no contactless, no AUD, no Khmer riel. The ATMs on the Cambodian side of Immigration are designed to dispense Khmer riel for taxis and dinner, not USD for visa fees. The cash-USD trap is the single most common reason Australian travellers end up annoyed at the VoA queue.
The fix is genuinely simple if you sort it in Australia before you board: walk into your bank or a Travelex branch a week out, ask for $40 USD in $5, $10 and $20 notes, and put them in a clean envelope inside your carry-on. The catch is that nobody tells you this until you are already at the airport in Phnom Penh wondering why the friendly ATM beside you is spitting riel. This guide walks through where to source clean small USD in Australia, what the AUD-to-USD margin actually costs in 2026, and why the on-arrival ATM is not the fix some Aussies assume it is.
If you are still weighing visa on arrival against the eVisa, the airport-by-airport reliability guide and the head-to-head comparison cover that decision in more depth. If you have already chosen VoA, this guide is the cash-prep walkthrough that should sit beside your passport.

What the VoA booth accepts (and what it refuses)
The Cambodian VoA booth has run on US dollars for over twenty years. The country itself uses USD alongside the Khmer riel for almost every higher-value transaction, and Immigration has standardised on USD because it keeps the booth process consistent across all three airports and both land borders. What changes in 2026 is the stricter enforcement of note quality. The officer at the booth is now expected to refuse any note with visible damage, ink, fold creases through the serial number, or tears at the edge — and Aussies in 2026 are being sent back to the ATM more often than they used to.
Why clean small notes matter so much
Pertanyaan yang sering diajukan
Can I pay the Cambodia VoA fee in Australian dollars?
No. The Cambodia VoA booth at KTI, SAI and KOS — and at the Bavet and Tropaeng Kreal land borders — accepts US dollars only in 2026. Australian dollars are never accepted, even at booths where the officer recognises the currency. Khmer riel is also refused for the visa fee. The fix is to bring USD cash from Australia or to use the eVisa, which is billed in AUD at checkout.
How much USD should an Aussie bring for Cambodia VoA?
Bring $40-$50 USD even though the fee is $30 (~$46 AUD). The buffer covers a missing-photo backup ($2 USD, ~$3 AUD), a possible unofficial express-line tip ($5 USD at KTI peak), and an arrival-side taxi if you end up paying in USD. Anything left over is useful for hotel deposits and tuk-tuk drivers in Phnom Penh and Siem Reap, where USD circulates alongside Khmer riel.
Where is the best place to buy USD in Australia for Cambodia?
Pre-order through your home bank — ANZ, CBA, Westpac or NAB — at least 48 hours before flying. Bank pre-orders typically sit at 2.5-3.5% over the spot AUD/USD rate in 2026, compared to 5-7% at airport Travelex counters. Specify $5, $10 and $20 denominations on the order. A $40 USD pre-order costs around $63-64 AUD; the same purchase at an airport kiosk costs $66-68 AUD.
What is the AUD-to-USD exchange rate in 2026?
AUD/USD has traded in a 1.52-1.55 band through the first half of 2026, with a mid-point around 1.535. Each $1 USD costs roughly $1.53-$1.55 AUD before retail margin. A $30 USD VoA fee is therefore around $46 AUD at spot and $48-50 AUD after a reasonable bank margin. A $40 USD cash budget is around $63-65 AUD pre-ordered, $66-68 AUD at airport kiosks.
Can I withdraw USD from an ATM inside the Cambodian airport?
Some ATMs at KTI dispense USD in $20 or $100 increments, but they are not located beside the VoA booth and they charge around $5 USD (~$7.50 AUD) per withdrawal on top of your home-bank fee. The ATMs immediately past Immigration are stocked for taxi fares and dinner — they dispense Khmer riel, not USD. Bringing cash from Australia is faster and cheaper than the on-arrival ATM round trip.
Why does the VoA booth refuse my $20 note?
Cambodian Immigration enforces a strict note-quality rubric. Notes are refused if they have visible ink marks, tears, fold creases through the serial number, or a series date earlier than 2006. A $20 note that looks fine for a Sydney cafe can be refused at the booth. The fix is to pre-order fresh notes from your Australian bank a week before flying and to store them in a clean envelope rather than a worn wallet.
