If your income is taxed in Australia, this will not happen. Australia also has a double taxation agreement with Thailand. Just read the terms and conditions there. 35% tax would only be due on income of 5 million baht. 30% on 2-5 million, 25% on 1-2 million, etc. So don't let it drive you crazy. At the moment there is just a lot of hot air.
Things are not as hot as they seem. It mainly concerns the big fish or companies that have deregistered in their country of origin and therefore do not pay any taxes at all. It will not affect all other countries with double taxation agreements significantly. Taxes here are cheaper than in Europe, so nothing can come of it. From the looks of it so far, a lot of hot air for nothing (if you have paid taxes up to now).
I got my driving license a few months ago. All in all it cost about 30 euros. The most expensive were the two letters from immigration (you need one for the car and one for the Motorcycle). Had the national and international driving license with me. The Thai driving licenses (at least mine) are initially valid for 2 years valid and will then be extended for a further 6 years.
The announcement alone does not constitute legal implementation. All laws only become effective when they are passed into law by the Royal Thai Gazette. And this always appears on Thursday. But because of the few euros or dollars it doesn't really matter. Within a few days I have the online visa And basing my holiday planning on a possible imminent visa arrangement is quite a strong thing
