I don't think the current board would be categorised as outstanding, but I don't think they have been disastrous either. Australian Rugby is in a shambles and borderline broke, and consequently some tough decisions have/had to be made. Obviously the toughest of these so far was the Rebels, but I don't think you could definitively say other adminstrators would have done anything different, given the $20m black hole that came with it.
It seems that the criteria of a successful administration to some here is to fix Australian Rugby within 3 months, otherwise they have failed and need to be moved on. The current lot are at least making some broad decisions in the right direction e.g. centralisation, but the main game is going to take time and money. The money will come from the BIL tour and then the home World Cups, it's what they then do with it that will then define them, but barring some outrageous carry-ons in between now and then we just need a bit of stability and leadership.
