Siem Reap-Angkor International (SAI) is the airport about 90% of leisure Aussies fly into for Cambodia — it's the gateway to Angkor Wat. The new terminal opened 16 October 2023, sits ~50 km east of town, and changed the arrival math for every Angkor-bound Australian.

SAI opened 16 October 2023 and is the airport ~90% of leisure Australians fly into for Cambodia — it's the gateway to Angkor Wat. About 50 km east of Siem Reap town centre (the new airport is much further out than the old REP was), 45–60 minutes by tuk-tuk or taxi for $15–25 USD (~$23–38 AUD). Bring your printed Cambodia eVisa (2 paper copies), your e-Arrival QR, and small USD bills for the airport transfer. Immigration queue typically 10–20 minutes; baggage claim is fast.
If you are an Australian flying to Cambodia for a holiday in 2026, the odds you land at Siem Reap-Angkor International (SAI) are roughly nine in ten. Angkor Wat is the headline reason Australians visit Cambodia — the temples sit just outside Siem Reap, and SAI is the closest international airport to the Angkor Archaeological Park. Phnom Penh (KTI) is the business and government hub; Sihanoukville (KOS) is the southern coast and Koh Rong islands. Almost everything else — the temples, the floating villages on the Tonle Sap, the Cambodian Circus, the night markets, the cooking classes — starts in Siem Reap.
SAI itself is new. It opened on 16 October 2023, replacing the old Siem Reap International (REP) that sat much closer to town and to the temples themselves. The new terminal sits about 50 km east of Siem Reap, on a fresh stretch of road built specifically for the airport opening. The trade-off is real: the terminal is bigger, quieter, and modern, but the transfer into town now takes 45–60 minutes rather than the 15 minutes the old REP used to. Every 2026 Aussie travel guide that still references REP is out of date.
The single biggest change in moving from REP to SAI is distance from town. The old airport was close enough that you could realistically tuk-tuk from a temple back to a departing flight in 30 minutes. The new one is not. Everything else — terminal size, queue length, baggage speed, food and shopping — improved when the airport opened. The table below is the honest side-by-side an Australian planner needs.
The 50 km transfer is the part most Aussies underestimate. The new road is Highway 6's alternative — long but smooth and sealed — and on a normal day the run takes 45 minutes. Add 10–15 minutes if you land in late-afternoon Siem Reap traffic on a Sunday. Three options out of the terminal: tuk-tuk from the rank just outside arrivals at $15–20 USD (~$23–30 AUD), airport taxi at the fixed-rate desk at $20–25 USD (~$30–38 AUD), or hotel pickup arranged ahead of time, which is often free if you are staying three nights or more. Grab (the regional ride-hail app) also works at SAI; expect $13–18 USD via Grab depending on time of day.
There is no train link between SAI and Siem Reap, and the local public bus is slow and infrequent. For an Australian arriving tired off a long-haul, road is the only practical answer. Pay the tuk-tuk in USD if you can — drivers prefer it, and the rate is fairer than KHR Riel converted at the airport rate.

Erste Reise nach Kambodscha? Hier ist die ehrliche Checkliste für Erstbesucher aus Amerika — das Visum, die US-Dollar-Geldbesonderheit, die Sicherheitsrealität, die Impfungen, der Tempel-Kleidungsstil und wie die Ankunft am neuen Flughafen im Jahr 2026 tatsächlich aussieht.
Alle sieben Landgrenzen zwischen Thailand und Kambodscha sind seit Juni 2025 geschlossen, daher ist in 2026 der einzige Weg für Amerikaner, von Thailand nach Kambodscha zu gelangen, das Flugzeug. Hier erfahren Sie, wie die Routen Bangkok-nach-Siem Reap und Bangkok-nach-Phnom Penh funktionieren, welches Kambodscha eVisa Sie vor dem Boarding benötigen, und warum der alte Poipet-Überlandplan nicht mehr existiert.
Drei Möglichkeiten, die 310 Kilometer zwischen der Hauptstadt Kambodschas und Angkor Wat zurückzulegen: ein $15 Expressbus, ein 45-minütiger Flug oder eine langsame Flussfähre. Hier erfahren Sie, was jede Option für einen amerikanischen Reisenden tatsächlich kostet, wie lange sie dauert und welche zu Ihrer Reise passt.
SAI has a smaller lounge selection than KTI. Plaza Premium is present and is the lounge most Aussies with a Priority Pass, Amex Platinum, or business-class boarding pass will use on departure. Food and shopping airside is modest — a couple of cafes, a duty-free, a small souvenir shop. Do not plan to do serious shopping at SAI; the night markets in Siem Reap town beat anything in the terminal by a wide margin.

The arrival flow at SAI is short and predictable. Off the aircraft, follow the Arrivals signs (the airport runs trilingual Khmer/English/Chinese signage, but the directional symbols are universal). The walk to Immigration is roughly 5–8 minutes from the gate. Split into the foreigners queue — there is a separate Cambodian nationals lane, do not stand in that one. The whole process at SAI is three steps and rarely takes more than 20 minutes for an eVisa holder.
After the stamp, you walk through to baggage claim. SAI baggage is genuinely faster than it was at the old REP — fewer wide-body arrivals overlap in the schedule, so most flights see bags on the belt within 10–15 minutes of touchdown. Customs is a green-channel walk-through unless you are declaring something. Out the door, the tuk-tuk and taxi rank is on your immediate right.

Once you have your passport stamped and your bag in hand, the first hour in Siem Reap sets the tone for the trip. Four things to sort before you fall into your hotel bed.

Four mistakes account for nearly every messy SAI arrival we see at the VisaToCambodia desk. None are catastrophic, but each can cost you an hour or several hundred dollars.

On the way out, the SAI departure flow is straightforward but the airport is far enough from town that you need to leave earlier than the old REP days. For an international departure to Bangkok, Singapore, or onward to Australia, plan to leave your Siem Reap hotel three hours before scheduled departure. The drive itself is 45–60 minutes, check-in opens 2.5–3 hours before departure, and Immigration on the exit side runs 15–20 minutes at peak.
There is no airport departure tax to pay at the counter — it is bundled into your ticket. Hand over the second printed copy of your eVisa (the one the Immigration officer returned to you on arrival) along with your passport at the exit Immigration window. You will not need the e-Arrival on the way out, only the eVisa.
Airside at SAI is modest. The duty-free is small, the food court has a handful of options (Cambodian, Thai, generic Western), and the Plaza Premium lounge is the main paid lounge. Power outlets are present at most gate seating areas. Wifi is free but slow — if you are working remotely on the way out, expect to tether to a local SIM. Most gate stores close around 9 pm, so late-evening departures are quieter and you may want to eat in town before you leave.
