He may have left a "Fancy Job" and by the looks of it, it was with Westpac then before that was NAB, he doesn't seem to stand still for too long but having said that i wouldn't want to be finance director of Westpac or Nab at the moment.
He would have to have gained some knowledge over the years so we'll see how he goes i guess.
