Yes, I assumed that was fine. But what about a test, you had no test before or on arrival?

Any recent experience entering thailand with no testing or vaccine stuff, just the same as 2019? I notice they mention unvaxed with no test will basically be at the discretion of the health control officer on arrival. What does this actually mean in real life on the ground? "Unvaccinated/partially vaccinated travelers who have proof of a negative COVID-19 test result within 72 hours of travel will be allowed to go anywhere in Thailand, while those who will arrive without a negative test result will be subject to health protocols deemed appropriate by the Health Control officer at the point of arrival."

You could but you would have to do your 30 day extension first. Its unlikely you will be able to utilize a covid extension though. The end date is today (24 Aug) and nobody is expecting it to continue this time considering they only moved the date 1 month. If nothing happens in the next day or two I would say its over.
