You got me on Thailand but the rest of the countries you mention are not first world. https://en.wikipedia.org/wiki/Three-world_model

Perhaps I meant to say “non first world” rather than third world, as well

I'm Australian. To visit the USA as a tourist, it's US$160 for a Tourism B-2 visa or US$21 for the ESTA under VWP. I might be missing another option as a tourist, but the ESTA is certainly the encouraged option and one I've used a couple of times before.

Foreigners will soon be required to apply for an ETIAS to visit Europe where previously I didn't need a visa to visit from Australia.

Is the EU third world too?
