I don't know. If someone stays five years they're going to be spending money somehow. I know people who have got the five years just on dental treatment. The visa doesn't have the reason mentioned. Just the finish date, which is five years. All you have to do is keep bouncing and stay away from immigration! The sources I have are people who are doing it, not talking about it!
I'm talking about the interest I'm missing out by not having my money invested in Australian Super. The 800k must stay in the Thai bank account paying 1% interest until the day you die. The 65k transfer you can spend as soon as you get it
