I am an Australian and entered Thailand for 60 days at Suvarnabhumi on a multi entry tourist visa on 2 May. I have recently got my 30 day extension. I know that if I fly to Penang and back at the end of July, I will be stamped in for another 60 days. My question is...if I border bounce to Cambodia with a reputable company at the end of July, will I be stamped in for 30 days or 60 days using the land crossing?
TLDR : Answer Summary
An Australian traveler with a multiple entry tourist visa who crosses from Cambodia back to Thailand will receive a 60-day stamp, provided they enter before their visa's expiration date. Entry method (land, air, or sea) does not affect the duration granted.
