Can an Australian tourist do a border run after extending their 30-day visa in Thailand?

Sorry, I'm not going to keep this post open. Just telling you about the written rules.

If anyone has any important information to be added, please contact one of the moderators to re-open this post.

The written rule is that the limit on land border entry on visa-exempt is twice per calendar year. As long as he is within this limit, he can enter Thailand again through the land border.

Other restrictions vary by the location of the border and also depending on his previous history of travelling to Thailand.

This group doesn't recommend or go into detail about border-bounce. Please try to post on the local expats groups related to where your friend lives or the border is located.

One thing this group can advise is, the Poipet Cambodian border would be not easy to bounce, even using the service.
