Tourist Visa or MTV

Hi there needing some advice as a tourist.

I found some previous threads about it the matter, but the rules keep changing constantly.

First came to Thailand in November 2025( stayed for 10 days) left to Indonesia and then back home to Australia.

Came a second time to Thailand end of January 2026 ( stayed for 7 days returned back to Australia.

Came a third time to Thailand in March 2026 ( stayed for 14 days)

Coming a fourth time to Thailand in June 2026

( staying a longer period 42-45days)

Hoping to make fifth trip in September 2026 ( for 24 days)

Final trip in November for (14 days approx)

So technically that would be 5-6 trips in a year.

My question is, is this going raise any red flags?

I know it’s been multiple visits.

They do vary each time, duration that is.

I am currently an Australian passport holder.

Stable health job.

I have excessive leave hence the multiple trips.

Is it safer to apply for MTV?

I know sometimes it does vary on immigration officer.

And could someone post the proper link to apply form if i do indeed need to apply for MTV in Australia.

Thank you
