Thailand is visa-free 60 days for Aussies in 2026 — no application, no fee, no paperwork. Cambodia is $80 USD (~$122 AUD), approved in 3 business days. Here is the honest friction comparison for your 2026 holiday — and why the closed land borders mean you cannot combine them overland anymore.

Thailand is easier on the paperwork — Australian passport holders get visa-free entry for 60 days at any Thai port, no application, no fee, no advance work. Cambodia requires a visa: our Tourist eVisa is $80 USD (~$122 AUD) all-in, approved in 3 business days, delivered as a printable PDF by email. Two extra wrinkles for 2026: Cambodia also needs the 14-field e-Arrival Card before you fly ($5 USD / ~$7.50 AUD verified through us), and the seven Thailand–Cambodia land borders have all been closed since June 2025, so you cannot combine the two countries overland this year. Friction-wise Thailand wins; experience-wise they answer different questions.
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.
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 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 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.

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.

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.
