I'm not familiar with ING Direct but its parent company, ING Group, is one of the big three in the Netherlands; it serves millions of customers. I have a current account and a savings account with its Dutch subsidiary, ING Bank N.V., and I'm generally happy. It's no less of a reputable business than any other bank. ;) My only beef with ING Bank N.V. is that their strong market position allows them to give only a pittance in interest compared to smaller Dutch banks, but that doesn't seem to be the case with ING Direct in Australia.
