I don't have enough insight into what goes on in the boardroom to have a definitive opinion on the presidents role, but regardless of that the time comes for all in these sort of roles. Whats important is having the right person to take over, and for these things to occur in a clean manner.
I was wondering whether someone like Jay Weatherill would be up for it at some point - hes definitely an active and passionate suporter, has all the right connections, is pretty good at choosing his words wisely etc. Clearly the downside is hes currently working in WA for Twiggy Forrest.
At least in politics they seem well versed in moving people on.
