I must say that I don't rate the possibility of success here as being very high at all.....only ever heard of David beating Goliath in the Bible.
As a poster earlier mentioned, I would think that ANZ will walk away from this with little other than their reputation tarnished....but the year on year multi-billion dollar profits they book will ensure that that will all soon be forgtton anyway.
Nevertheless, I wish you, and others, well with your crusade.
