This really is getting to the root cause in my opinion. There will always be personalities, egos, politics and disgruntled members no matter who is on the Board or the Executive. That's not the issue. The real issue is that RAAus has grown so big so quickly and being managed by a Board made up of volunteers is no longer the right model for an organisation of this size. There's only so much it's reasonable to expect of volunteers. Further, the fact they are popularly elected (or elected unopposed in some cases) is no guarantee they have the capability to manage the organisation.
If this was an organisation where what the members wanted was the primary issue then maybe we could continue with the volunteer Board management model, but the reality is that the primary task for RAAus is to meet the legal requirements necessary to protect the members' flying privileges. It's not an aero club or a flying school, it's a body charged with administering recreational aviation on behalf of the regulator. And doing that for a fleet of over 3,500 aircraft and well over 10,000 pilots requires skilled and professional people at all levels. An elected Board is necessary to protect the members' interests, but the Board should be an oversight function, not running the organisation. We need to separate management and governance. And as Kaz has suggested, they need professional guidance and support, not on aviation but on things like business and governance.
