No doubt wine is vastly cheaper in Australia and BYO , I could go any places for 2 for $60 plus my Dan's wine .
That being said I have lived in HH 7 years , and my rent for a small house is around 10.5 k baht a month , always think in baht , exchange rates are exchange rates .
Invest in Australia , maintain tax status and reside in Thailand if you are healthy, which I am .
