Help please, we are Australian passport holders and travelling since beginning of this year. I don't know how but it completely slipped my mind to go to the Thai Embassy in Hanoi where we have been staying the last few weeks and apply for a Thai visa. 🙄😬 So I know as Australians we are visa exempt for the first 30 days but how do we get our visa time covered after that? We will be staying 28 days in Bangkok, then a month in Chiang Mai before staying another 28 days in Bangkok? Preferably not having to do a visa run. Any help appreciated. We will be leaving Hanoi for Bangkok this Sunday. Thank you!
TLDR : Answer Summary
Australian passport holders can enter Thailand visa-exempt for 30 days. To extend their stay, they can apply for a 30-day extension at a local immigration office for a fee of 1900 baht. After that, they can leave Thailand and re-enter for another 30 days, ideally by air. It is important to ensure that they have onward flight arrangements to avoid issues with airlines regarding boarding.
