Will my wife face issues entering Thailand with a different name on her Thai passport compared to her Australian passport?

I am agreeing with you. Why would anyone have a passport in a name that is not their own? Furthermore to this expect there not to be problems down the line.

The first thing to do is get both passports in her name whichever passport is wrong then correct it. If it is the Thai Passport the process to Chang the name is very simple. Go to your nearest Thai Embassy with the passport and documents supporting the name change and they will make the nessessary changes. In our case it was an observation on the first blank page of the passport. All airline tickets were purchased in her married name. When the passport was renewed the new passport was in my wife's married name.

Alternatively as Rob says your wife continues to use her maiden name.

we are talking about going to Thailand under Thailand Pass

I was wondering the same thing

. Vaccination never came up in the question, so I was also wondering why she just doesn't use the Thai passport when entering.

In any case, think when hitting the immigration, she should just present both passports, if the vaccinations and Pass were done under the non Thai name.

her Covid vaccinations will most likely be in her Aussie name, so the question is valid.
