Hi, can i holiday in Thailand for 2 weeks, i have an Australian drug conviction, regretful mistake 8 years ago

No questions are asked on the arrival card on any convictions. Unless your on some wanted listed your have no problems

You won't have any problems, you don't get asked about any previous convictions or cautions when you enter Thailand so don't worry. Have a lovely time

Just be a good boy while in Thailand and you'll be fine.
