Do I need to apply for both visas before flying?
For most Australian, UK, US, EU, Canadian and NZ passports, only Cambodia needs to be sorted in advance. Thailand is granted at the border under the visa-exemption scheme. Always confirm your passport is currently visa-exempt for Thailand before you fly.
Which country is easier to enter as a tourist?
Thailand is slightly easier for visa-exempt nationalities because there is no fee or online step. Cambodia is straightforward if you sort the eVisa online — both countries process tourists in volume every day without drama.
Can I cross from Thailand to Cambodia overland?
Yes — Poipet and Koh Kong are the busiest crossings. Your Cambodia eVisa is accepted at both. If you only have Visa on Arrival you will need USD cash and a passport photo at the Cambodian side.
How long can I stay in Cambodia vs Thailand?
Cambodia tourist stays are 30 days single entry. Thailand visa exemption is typically 60 days for eligible nationalities and can be extended by 30 days at a Thai immigration office. Confirm your passport length for both stays.
Are there COVID-era entry rules still in force?
No. Both Cambodia and Thailand removed pandemic-era health requirements. Standard tourist documentation is the only entry condition.
Which visa should I sort first for a combined SE Asia trip?
Apply for the Cambodia eVisa first — it has a lead time and pre-approval requirement. Thailand handles itself at the border for most travellers, so leave it for last.
