Thailand–Cambodia Border Update 2026: All 7 Land Crossings Closed (What Australians Need to Know)

How to rebook if your itinerary assumed Bangkok–Siem Reap overland

• Cancel or refund the Thailand-side onward leg first. Most Thai bus operators on the Bangkok–Aranyaprathet route processed automatic refunds in 2025; if yours did not, email the operator with the booking reference and the closure date and they should refund. 12Go Asia handled refunds at scale.
• Book Bangkok → SAI (Siem Reap) as the direct replacement if Angkor Wat was the destination. It's a one-hour flight, several departures daily, and low-cost carriers route through Don Mueang (DMK) at the cheapest fares.
• Or book Bangkok → KTI (Phnom Penh) if Phnom Penh was the destination. Also a one-hour flight, slightly more frequent than SAI, and KTI is the smoother airport for arrivals.
• If you're stretching the budget, a Bangkok–Kuala Lumpur–Phnom Penh routing through AirAsia is sometimes cheaper than the direct flight, at the cost of three to four extra hours.
• Re-time the Cambodia eVisa application around the new flight date — the eVisa is valid for 3 months from issue, so a small flight-date shift is rarely a problem. The 30-day stay window starts at the immigration desk, not at issue.

Don't book the flight before the eVisa is approved if your trip is tight on time. The Cambodia visa processing time from Australia is three business days, weekends and Cambodian public holidays don't count, and a Friday-afternoon submission can land approval the following Wednesday. Once the approval PDF is in your inbox, book the flight that matches the date you're realistically arriving.
