Gavin,
Really, all we want from our RAAus representatives is honesty and integrity. Yes, you are volunteers, but, as has been pointed out, legally the buck stops with you. You make mistakes, so be it, acknowledge them, correct them and get on with the job.
Unfortunately, your posts here have so far followed the prime directives of the Politician's Book of Spin 101.
Blame the previous incumbents.
Attack is the best form of defence.
I didn't know you were a freemason. I don't really care. Please credit your members with more intelligence than to be influenced by unsubstantiated rumours.
Just tell it like it is. A cursory glance through these many threads on the subject shows the amazing breadth of intelligence and experience that RAAus members have in areas such as aviation (both civil and military), law, accountancy, IT and vast experience on Boards both for-profit and not-for-profit. I bet most of this experience is yours for the asking. Eat some humble pie and ask. I, for one, would admire you and the other Board members for it.
