I've have been on a few boards. I'm on one now. And I do have some first-hand insights into the way in which the boards of Commonwealth statutory authorities work.
Can you nominate any CEO of any Commonwealth statutory authority who's ever "resigned to pursue other opportunities". Mark Skidmore bailed out early, not because of any pressure put on him to jump by the CASA Board or Minister, but rather because he quickly worked out what a sh*t show he'd inherited and that sacrificing his sanity and reputation weren't worth the pieces of silver.
