What visa should I get for multiple entries every three weeks to Thailand from Australia?

I'm on a 4 week rotation. 4wks in Thailand tgen 4wks out. I've been doing this now for 3 years, so 5-6 visa exemptions (I'm from the UK) per year.

The last 2 times I've entered Thailand have been horrendous! My last entry was on tge 31st of December and I genuinely thought I was going to get turned away. I took my nearly 30 mins of answer questions, and having to deal with 2 supervisors, before they finally let me in.

Exemption is ok for a while, but doing it regularly won't last forever.

I'm now trying to come up with a suitable plan for myself.

No changes to visas. Though visa EXEMPT is 60 days for many countries. Just a bit more scrutiny on people entering who try to live in Thailand without visas.

DTV easy peasy!

What age are you, are you married to a Thai?

I have work mates doing it on a roster we fly in every month they are not being questioned. Infact they get through immigration quicker than me as many IO dont know what OX visa is and have to call a senior.

i have friend from Melbourne who did this last year with visa exempt. 9 entries. Should not be a problem as your flying back to your home country and your not maxing out on 60 days and doing border bounces

Depends on your situation

Over 50 a Non-O or Non-OA based on age

Married to a Thai a Non-O based on marriage

Neither of the above there's not much choice, you could look at the Thai Privilege visa
