Wannikea Wanblee. Thanks for that. I am actually already a member of that group, but there is a lot of very useful information still being posted to the old group.
Ensure you are fully vaxxed before you come. Moving around Thailand in the future is going to be difficult and expensive if you need continual tests. There are also rumours (probably not totally unfounded) that future visa extensions will require vaccines. You may already be vaccinated, but if not the process in Australia is much easier than Thailand
