I read that people coming from countries affected by yellow fever have to present proof that they've had this vaccine in the last 10 years upon arrival in Thailand.
I'm a Brazilian citizen and Brazil is partially affected by yellow fever. However, I have not lived in Brazil for many years and I will be coming to Thailand from Australia.
I'm from São Paulo, an area which is not affected, so I've never had this vaccine, even when I lived there. I have never been to any affected areas.

Do I still need proof that I've had this vaccine? Is that really reinforced?

Thanks

The need for the vaccine is determined on the base of the country, not part of the country.

But the criteria is travelling from one of those countries, or having been in one of them in the last .... months. I thought 6 months, but not sure.

As oyu have not lived there for years, you do not need a yellow fever vaccine. But be prepared to show that you have not been to brazil in the last X months.

I traveled with a friend who used a Peruvian passport alhtough he had resided many years in Japan without going back to Peru. He was able to enter Thailand after showing his residency in Japan. I suggest you also email the closest Thai consulate to you in Australia just to have some reference when you arrive.
