Thailand is visa-free for Australians in 2026 — 60 days on a passport stamp, no application, no fee, granted at any Thai entry port.
Cambodia is NOT visa-free for Australians — $80 USD (~$122 AUD) all-in Tourist eVisa, approved in 3 business days, delivered as a printable PDF by email.
All 7 Thailand–Cambodia land borders have been closed since June 2025 — you cannot combine the two countries overland anymore.
Flying is the only way to enter Cambodia from a Thailand trip in 2026 — Bangkok or Chiang Mai to Phnom Penh (KTI), Siem Reap (SAI), or Sihanoukville (KOS).
Thailand wins on paperwork friction; Cambodia wins on Angkor Wat. They are not the same trip — pick the country you actually want to see.
เหตุใดชาวออสเตรเลียจึงยังคงถามคำถามนี้ในปี 2026
This guide is the friction comparison, not a destination shootout. If you want the destination-decision angle, the Cambodia visa cost guide for Australians and our Do Australians need a Cambodia visa pillar cover the eligibility detail, and the Cambodia visa processing time piece is useful if you are weighing a last-minute booking. Our Cambodia eVisa for Australian travellers pulls all the pieces — cost, documents, processing — into one place.
กฎระเบียบเกี่ยวกับวีซ่าแบบเคียงข้างกัน
Australian passport-holders need a Cambodia visa — no exceptions, no visa-free window, every traveller including infants. Our Tourist eVisa is $80 USD (~$122 AUD) all-in for a 30-day single-entry stamp valid for three months from issue. The Business eVisa is $90 USD (~$137 AUD) for the broader category covering meetings, paid work, conferences, sales calls, supplier visits, and longer stays. Both are processed in 3 business days. The all-in price includes passport and photo pre-checks, Aussie-timezone support, the approved PDF emailed to your inbox, and free resubmission if Immigration flags a correction. The eVisa-vs-VoA comparison covers why this beats the cash queue at Phnom Penh airport.
The pre-arrival timeline for an Aussie holiday
Passport with 6 months validity remaining from your Thai entry date — same rule as Cambodia.
Return or onward ticket (most airlines spot-check this at check-in in Australia; Thai Immigration rarely asks).
Proof of accommodation for the first night (occasionally asked — a confirmed booking is enough).
TDAC submitted within the 3-day window before arrival — free, online, takes about 5 minutes per traveller, save the QR.
No visa fee, no application, no advance lodgement.
Passport with 6 months validity from your Cambodia entry date and at least one full blank visa page.
A digital passport-style photo (white background, 600x600 pixels minimum — phone photo is fine if framed correctly).
Tourist eVisa lodged at least a week before flying — $80 USD (~$122 AUD) all-in, approved in 3 business days, delivered as a printable PDF by email.
e-Arrival Card submitted in the 7-day window before arrival — 14 fields, $5 USD (~$7.50 AUD) verified through us, separate from the visa.
Print the eVisa PDF or save it offline on your phone (KTI Wi-Fi at Immigration is unreliable).
The desktop walkthrough has the field-by-field for the eVisa form, and the e-Arrival 14-fields walkthrough covers the arrival card. For a tight booking window, the Friday application timing piece is worth reading before you lodge — Khmer public holidays can push the three-business-day clock further than Aussies expect.
The closed land border: why you cannot combine them overland in 2026
The good news: flights between Bangkok and Cambodia are short, cheap, and frequent. Bangkok to Siem Reap (SAI) is about 1 hour on Bangkok Airways, AirAsia, or Cambodia Airways — fares from BKK to SAI are typically $80 to $180 AUD one-way depending on the season. Bangkok to Phnom Penh (KTI) is similar. From Chiang Mai you usually connect through Bangkok. The full Thailand border closure update has the diplomatic background and the operational detail, and the Cambodia airports guide breaks down KTI, SAI, and KOS for first-time Aussies.
The honest friction comparison
Thailand's 60-day stamp gives Aussies more room than they need for a single trip. Cambodia's 30-day Tourist stamp is single-entry — once you exit, the visa is finished. For Aussies on a 10 to 14-day Cambodia trip the 30 days is plenty; for slower long-stay travellers, Business eVisa or extensions are the route. The 12-month Cambodia extension piece covers that, and the Cambodia eVisa edge cases piece covers the unusual situations.
How a Thailand-plus-Cambodia trip actually looks in 2026
Days 1–6: Bangkok in (BKK), Chiang Mai by overnight train or 1-hour flight, return Bangkok. Thailand visa-exempt 60-day stamp covers the whole leg.
Day 7: Fly Bangkok (BKK) to Siem Reap (SAI) — about 1 hour, $80 to $180 AUD one-way on Bangkok Airways, AirAsia, or Cambodia Airways.
Days 7–10: Siem Reap — Angkor Wat at sunrise (allow at least 2 full days for the temples), the Old Market, Phare Circus, a day trip to Beng Mealea or Kbal Spean.
Days 11–13: Fly or bus Siem Reap to Phnom Penh — riverside, Royal Palace, Tuol Sleng, Russian Market, a Mekong sunset cruise.
Day 14: Fly Phnom Penh (KTI) home via Singapore or Kuala Lumpur — Cambodia 30-day single-entry stamp is fine for this.
Total visa cost: $80 USD (~$122 AUD) Cambodia eVisa plus $5 USD (~$7.50 AUD) verified e-Arrival = $85 USD (~$129 AUD) per traveller for both countries.
If you want a deeper Cambodia leg, the 7-day itinerary for Aussies and the 14-day itinerary cover the on-the-ground shape, and the Cambodia first-trip planning checklist is the full pre-departure list for first-time Cambodia visitors.

No. Australian passport-holders get a visa-exempt entry stamp valid for 60 days at any Thai international port, granted automatically by Immigration on arrival. There is no application, no fee, and no advance lodgement for tourism. You will need to fill the free Thailand Digital Arrival Card (TDAC) within the 3-day window before arrival — it takes about 5 minutes and produces a QR code you show at the Immigration counter. Your passport must have at least 6 months validity remaining from your Thai entry date.
Do Australians need a visa for Cambodia in 2026?
Yes — every Australian passport-holder needs a visa for Cambodia, including infants and dual citizens travelling on their Australian passport. There is no visa-free option. Our Tourist eVisa is $80 USD (~$122 AUD) all-in for a 30-day single-entry stamp valid for three months from issue. The Business eVisa is $90 USD (~$137 AUD) for meetings, paid work, conferences, sales calls, supplier visits, and longer stays. Both are processed in 3 business days and delivered as a printable PDF by email.
Can I cross from Thailand to Cambodia overland in 2026?
No. All seven Thailand–Cambodia land borders (Poipet, Cham Yeam, O'Smach, Choam, Prum, Daun Lem, and Phsa Prom) have been closed to tourist crossings since June 2025. The Thai Navy denied a reopening in April 2026 and the Cambodian Foreign Ministry has been quiet since. For any trip booked in 2026, the only practical way to enter Cambodia from Thailand is by air — Bangkok or Chiang Mai to Phnom Penh (KTI), Siem Reap (SAI), or Sihanoukville (KOS). Bangkok Airways, AirAsia, and Cambodia Airways all fly the route.
How long does it take to get a Cambodia eVisa from Australia?
Three business days from successful submission. The Tourist eVisa is $80 USD (~$122 AUD) all-in, the Business eVisa is $90 USD (~$137 AUD). The application itself takes about 15 minutes (passport scan, digital photo, card payment). Most Australian applicants lodge in the evening AEST and receive the approved PDF in their inbox two to three business days later. Khmer public holidays can extend the clock — the Friday application timing guide covers when to lodge for a Monday flight versus a Thursday flight.
Is the Cambodia eVisa harder to get than the Thai visa-exempt stamp?
It is more work, not harder. The Thai stamp is granted automatically on arrival — no application, no fee, no decision pending. The Cambodia eVisa is a 15-minute online form, a $80 USD (~$122 AUD) payment, and a 3-business-day wait. There is no interview, no bank statement requirement, and no flight or hotel booking required to start. Australian passport-holders are approved at near-100 percent rates as long as the photo meets the spec and the passport bio-page is clean. We do passport and photo pre-checks before submission and offer free resubmission if Immigration flags a correction.
Can I use the same trip booking to visit both Thailand and Cambodia?
Yes — most Aussies on a multi-stop Indochina holiday do exactly this in 2026. The shape is air-only: Bangkok in on a visa-exempt 60-day stamp, internal Thai travel (Chiang Mai, Phuket, the islands), then fly Bangkok or Chiang Mai to Siem Reap (SAI) or Phnom Penh (KTI), spend 7 to 10 days in Cambodia on a 30-day single-entry Tourist eVisa, then fly home via Singapore or Kuala Lumpur. Total visa cost for both countries: $80 USD (~$122 AUD) for Cambodia, $0 for Thailand. The Cambodia visa lasts three months from issue, so you can lodge it before you fly to Thailand and not worry about it again.
Do I need the TDAC and the Cambodia e-Arrival Card?
If you visit both countries, yes — one per country, per traveller. The Thailand Digital Arrival Card (TDAC) is free and lodged within 3 days of your Thai arrival. The Cambodia e-Arrival Card is 14 fields and lodged within the 7-day window before your Cambodia arrival — separate from the visa. We verify and submit the Cambodia e-Arrival for $5 USD (~$7.50 AUD) per traveller, checked end-to-end before it reaches Cambodian Immigration. Both are mandatory for air arrivals in 2026.
Which one should I do first if I have never been to either?
Honestly, it does not matter much for the visa side — Cambodia's eVisa is valid for three months from issue, so you can lodge it before any leg of the trip. On the experience side, most Aussies recommend Thailand first because it is the gentler landing for Southeast Asia: more English in tourist zones, more familiar food, easier transport. Cambodia is more rewarding for travellers who want depth — Angkor Wat, the Tuol Sleng history, the genuine off-the-beaten-track pace. Thailand first, Cambodia second is the standard order for first-time Southeast Asia travellers.
Can I extend my Cambodia eVisa if I want to stay longer than 30 days?
Not on the Tourist eVisa — it is a 30-day single-entry stamp and the in-country tourist auto-extension ended in November 2025. For longer stays, the Business eVisa is the route: $90 USD (~$137 AUD) all-in, still 3 business days, and it can be extended multiple times in-country via a local agent. The Business eVisa covers meetings, paid work, conferences, sales calls, supplier visits, due-diligence trips, sponsored events, and any genuine business activity — but it is also the standard route Aussies use for long-stay tourism in 2026.
