It might have been asked before but, I'm planning to return to Thailand next week after my initial 5-day trip in mid-August this year. Are there any restrictions on the number of visa-free entries when traveling with an Australian passport?
TLDR : Answer Summary
There are no restrictions on the number of visa-free entries for Australian passport holders visiting Thailand, as long as the entry is not abused. Several users have confirmed that multiple entries within short time frames have not caused any issues.
