It's such a pity when any organsiation ends up at odds with the Corporations Act 2001 because ASIC are usually only interested in harvesting the tall poppy's. It takes someone with the funds to bring things to a close with minimal damage to the organisation.
Usually as I have witnessed, it is better just to resign your position after you have been compromised and watch the place implode.

However, much of it (other than a tiny number with deep pockets) is disunited, un-coordinated, incoherent and incompetent at lobbying government.
