My Thai friends are uncertain so I'd ask here. Anyone know if Thai National can travel to Indonesia? What's required for them to leave?
Getting into Indonesia is the easy part that I can help with.
If they can leave, is quarantine on return the same as for foreigners or treated differently now?
TLDR : Answer Summary
Thai nationals can indeed travel to Indonesia, though they may need a visa depending on the purpose of their visit. Upon returning to Thailand, these travelers have the option of taking a state-repatriation flight with quarantine in a government facility, or purchasing a ticket for a commercial flight and undergoing a self-funded quarantine in a hotel of their choice. Travel and immigration requirements can change frequently, so checking the latest guidelines from official sources is advisable.
