fwiw (i'm no longer a shareholder but lost heaps on vcr over many years) but can act as a proxy for personal family/ friends

there needs to be an organized representation to the VAs with some big guns on board ie. a specialist lawyer (must have)and possibly a rep from the shareholders assoc.
Call an interested SHs meeting before meeting with the VAs and invite the above people to attend (+ maybe a rep from ASIC?). Nut out a strategy which may include an application to the courts to stop the sale until an 'independent' shareholder approved audit is done. Then meet with the VAs with a proposal.
It may cost a bit of money for the lawyer but if you feel strongly that its not worth 'walking away' then its peanuts to the bigger picture
