Interesting. Tassie Greens leader Nick McKim has ruled himself out as the replacement Senator, which is surprising, because he has long been regarded as the anointed successor. People are now talking about Peg Putt (former state leader) and Greg Couter (the Greens candidate in Denison in 2010).
So, new party room will be as follows:
Milne (Tas) - Leader
Bandt (Vic) - Deputy
Di Natale (Vic)
Siewert (WA)
Ludlam (WA)
Hansen-Young (SA)
Wright (SA)
Rhiannon (NSW)
Waters (Qld)
Unknown (Tas)
Probably a good call by McKim, wouldn't exactly be the best thing or the best look for the leader of a party in coalition government who's also Deputy Premier to run off when a better job is up for grabs. Highly likely he'll be in Canberra at some point though. I got the impression from a few articles that Peter Whish-Wilson is favourate.
Siewert, Waters and Milne are genuine environmental activists. The others are more focused on social issues. In that sense, I don't really expect Milne to stay at the head of the party for too long. Her expertise isn't in the areas that most of the party room are most concerned with, and she doesn't have the personal cachet of Bob Brown.
I dare say the only reason she was elected unopposed is because Bob made it clear she was his anointed successor. Once he's out of the way, we'll see the real rearranging of chairs.
I don't think that being focused on the environment in what is still an environmental party, and having a position on the environment that most if not all people in the party share is grounds to remove a leader. Outside of Rhiannon and maybe SHY I don't think they're stupid enough to start leadership infighting a la Democrats unless Milne was failing anyway.
