I wasn't likely to vote Greens this election anyways, but even after she has quit, the damage done to the Greens by Shaw in defending her and carrying on the way he did a couple of days ago, has completely ensured I will not. He also needs to step down in my opinion. Nothing less would do. 

I find it most surprising she came out yesterday saying she wouldn't resign for any reason and today quits. I don't think they have a clue what is going on, and it deeply concerns me.

The dazzling lack of foresight by their advisors in the way this whole thing has been handled is unbelievable. A person with even a modicum of decency would have advised a much better course of action. A simple speech acknowledging the mistake, showing remorse, acknowleding how bad it looked and that she felt it was the right thing to do at the time for her family, but upon reflection she understands how wrong it was and what kind of example that has set, offering to resign but making a statement to the effect that they intended to do something to ensure that others didn't feel they needed to do the same would have been quite effective.
