KTI Arrivals Hall for Aussies: SIM Cards, Money Changers & ATMs on the Way Out

Money at KTI: USD cash from Australia, riel exchange, and ATM choices

Cambodia runs on a USD-dominant cash economy with the Cambodian Riel (KHR) used for change and small denominations. This is the single most important thing for an Aussie to understand before landing: the country bills almost everything in USD, including hotel rates, dive trips, restaurant menus, and tuk-tuk fares. Bring USD cash from Australia, exchange a small amount to KHR at the airport for sub-dollar change, and you're set.

How much USD to bring from Australia depends on how long you're staying and how cash-heavy your itinerary is. For a 7–10 day Aussie trip with hotels paid on a credit card and meals/transport in cash, $200–500 USD (~$305–765 AUD) in mixed denominations is the practical range. Pull the USD from your Australian bank in $20s, $10s, $5s, and $1s — large $100 notes are harder to break with tuk-tuk drivers and small market vendors. Skip $50s and $100s if you can; they're more often refused than accepted in everyday Cambodia transactions.

Exchanging USD to KHR at the airport

The KTI airport currency-exchange counter sits in the arrivals hall and typically posts a rate of 4,000–4,100 KHR per USD in 2026. The street rate in Phnom Penh is fractionally better (around 4,050–4,150 KHR per USD), but the airport spread is small enough that it isn't worth chasing if you only need a small amount. Aim to exchange $10–20 USD at the airport into riel — that gives you roughly 40,000–82,000 KHR which is plenty for a day of small change, water bottles, tuk-tuk top-ups, and tip money.

Do not exchange your full USD stash at KTI. Most Cambodian merchants accept USD directly without a conversion fee, and you'll lose money rolling everything into riel only to roll it back later. The riel you do hold is for transactions under $1 USD where USD coins do not circulate (Cambodia uses no USD coins — change under $1 is given in riel).

ATMs at KTI: Wing, ABA Bank, Acleda Bank

Three ATM brands matter in the KTI arrivals hall: Wing, ABA Bank, and Acleda Bank. All three are reliable, all three dispense both USD and KHR (you choose at the screen), and all three charge a flat withdrawal fee of around $4–5 USD (~$6–8 AUD) per transaction on top of whatever your Australian bank charges. Pull USD in $20 and $10 notes for the cleanest first day.

• ABA Bank — the most widely used ATM brand in Cambodia. Reliable, dispenses up to $500 USD per transaction, screen instructions available in English. The Aussie default.
• Acleda Bank — slightly older machines but very reliable. Also dispenses USD and KHR with English instructions. Useful backup if the ABA queue is long.
• Wing — a digital-banking ATM brand that runs cheaper transaction fees on its own Wing wallet, but for a foreign Aussie card the fee is similar to ABA/Acleda. Functional alternative.

Tell your Australian bank you're travelling before you fly — Westpac, Commonwealth, NAB, and ANZ all freeze cards on suspicious foreign withdrawals by default. A 30-second call to your bank's travel-notification line saves the headache of a frozen card on the second night. ING Direct and Macquarie offer rebated international ATM fees on certain accounts; if you have one of those, you save the $4–5 per withdrawal that ABA charges.

What not to do at KTI: AUD, $100 bills, and other Aussie mistakes

Five mistakes account for most of the messy KTI arrivals-hall sorts we see. None are catastrophic, but each costs an Aussie either time, money, or both.

• Bringing AUD expecting to spend it. Australian dollars are not accepted by Cambodian merchants, drivers, or even most currency exchanges outside the airport. If you arrive with AUD only, you'll exchange it at the KTI counter at a poor rate, lose 4–6% on the spread, and end up worse off. Convert AUD to USD at your Australian bank or a Sydney/Melbourne airport exchange before you fly.
• Bringing only $100 USD notes. Big bills are harder to break in Cambodia than in Australia. Tuk-tuk drivers, market stalls, and small restaurants often genuinely cannot make change for a $100 note. Mix your USD into $20s, $10s, $5s, and $1s before you fly — your Australian bank can do this for you on request.
• Exchanging your full USD stash at the airport. The airport rate of 4,000–4,100 KHR per USD is fine for small amounts but loses to the in-town rate at scale. Exchange $10–20 USD at KTI for immediate small change; keep the bulk of your USD in USD and spend it directly with most merchants.
• Skipping the SIM and roaming instead. Telstra and Optus international roaming day-packs run $5–15 AUD per day in Cambodia. For a 10-day trip that's $50–150 AUD versus $7 USD (~$11 AUD) for a local SIM. The local SIM wins on every metric except convenience.
• Forgetting passport for SIM registration. Cambodian telcos require passport ID to register a SIM (anti-fraud law). If your passport is checked into your hotel before you arrange the SIM, you cannot buy at a non-airport counter. Buy at KTI before you check in — the SIM takes one minute and your passport is in your hand anyway.

The 15-minute KTI arrivals-hall routine for Aussies

Done right, the whole on-arrival sort at KTI takes about fifteen minutes from the moment you walk out of customs. Here's the exact sequence we recommend Aussies follow.

• Minute 0–4: Walk past the customs green-channel exit and look right for the telco row. Pick Smart Axiata if the queue is short or Cellcard if Smart is busy. Hand over passport and $5–10 USD (~$8–15 AUD), wait for the SIM to activate, swap it into your handset, test mobile data on the terminal wifi.
• Minute 4–9: Move to the currency-exchange counter (next to the telco row). Hand over $10–20 USD, receive 40,000–82,000 KHR. Tuck the riel into a separate compartment from the USD bulk; you do not want to mix them.
• Minute 9–12: Walk to the ABA Bank ATM (the busiest and most reliable). Only withdraw if you arrived short on USD — the bank fee is $4–5 USD (~$6–8 AUD) per transaction, so a single $200 USD withdrawal is the efficient move rather than two $100 ones.
• Minute 12–15: Walk out to the taxi/tuk-tuk rank. Fixed-rate taxi desk is on your left; tuk-tuk is on your right. Pay the driver in USD (small bills), tip in riel for the friendly bonus, and head into Phnom Penh.

The whole sort can be done while your suitcase is still rolling next to you. If you have a hotel pickup arranged, run the SIM and the riel exchange first and meet your driver at the carded pickup point — they'll wait a few minutes, and most are used to Aussies needing one quick top-up before the drive into the city.
