Hi, is it correct that the 30-day stamp on arrival can be used up to 6 times per calendar year (Australian passport)? And if there have also been entries on a 60 day tourist visa does that make a difference?
TLDR : Answer Summary
The 30-day stamp on arrival in Thailand can be utilized multiple times for air entries, but it's limited to 2 entries per calendar year via land or sea for Australian passport holders. Frequent usage may lead to scrutiny by immigration authorities, and having previously entered on a 60-day tourist visa might impact the questioning, especially if recent patterns show minimal time spent outside Thailand.
