In Australia, any transaction over 5,000 AU$ gets reported. Well, makes an entry into the file. Unless the participants are under investigation, nobody cares.
Some people in Australian bush, when buying privately a second hand cars make the payments in 4,999 AU$ installments to avoid that reporting.
The records are kept for 7 years if something legal or criminal comes up and has to be back tracked.
I was in payment processing, I remember one transaction, Macquarie Bank, where one company sold a building to another for 200 million AU$. That certainly attracted some looks from the watchdogs but large trasactions like that happen every day, all day.
Do not worry about such paltry sums...unless...well, you know what I mean.
I did that for the non immigrant visa "O" from Japan, Osaka Royal Thai consulate asked only for the bio page of my Australian passport, not all the pages. 5 days and it was approved.
You may be right. The guy who told me that (he was the owner the first Thai related bulletin board in late 1990s) had been in Thai 10 years by then, legal work.
That kind of insurance must exist, Thais are en masse in it, may well be good for those who want some affordable insurance for real possibilities without open heart surgeries and supersonic evacuations cover and live in Thai long term.
My "extrension of stay 1 year" does not require health insurance, I may have a look into that.
Sorry, I can not. The guy who told me that in 2003, passed away last year but it is something Thai nationals would know (his wife was Thai, she made it). That is not a secret, someone here might know about that.
