really? Marry a Thai person and end up divorcing, then the Thai Government says 'get out'! Failure to have the required amount of money in the Bank Account ft the specified times and for the specified periods, or fail to comply with some of those other requirements & they'll kick you out, won't they? When you get a Visa to live in Australia, you can apply for Permanent Residency and within a few years, Citizenship. Only serious criminal offences would see one deported & other than that, residence is permanent. I'm sure that the other countries you mention are the same. Thailand it seems, can kick you out for very 'flimsy' reasons.
