ASk thai immigration they know everything about immigration

METV check on

2 months you get on arrival and extension 30 days at immigration,visa run get another 60 days 👍🏻

but you come for? If want to stay longer and unlimited entry try DTV

Embassy and consulates in Australia have varying authority to issue various visas. I suggest starting with the consulate in your state, like for NSW it is the Consulate General in Sydney. When I did it Christmas 2024 it allows single entry 60-day visa only, which can be changed and extended here.

Thai Embassy in Canberra was different as was Consulates in other States. I read recently one or 2 states now refer to Canberra for applying

What is the reason of your stay

Don't think they have one for There are several for regular people though

Best to look at the options available at the consulate you will apply through but it sounds like the Multiple Entry Tourist Visa (METV) would suit you. It's a 6 month visa that gets you stamped in for 60 days every time you enter which can be extended by 30 days, so you would need a border bounce to get the 2nd entry stamp
