Are you thinking of starting a business in Pattaya when you retire? Maybe an Aussie style near pie and sausage roll shop.
Or put on a sausage sizzle once a week, I'd come down from Bangkok for that. Might be a bit expensive but, cos you'd have to import the proper Aussie snags, Tip Top bread, Meadowlea margarine and Big Red tomato sauce. Or whatever brands you grew up with.
