cut the crap mate. I was a hippie, an acid head, a psychedelic thunderstorm back in the late 70s. These green couldn't even find their way to the dunnie let alone to policy.
Back then 'grass' was free and acid totally legal and that was what the "free" movement was all about.
There were no Bob Browns and Penny Wongs and life was s good.

Wrong Josephus, every party cannot represent "diversity" or it couldn't develop any specific policies!

And all parties would end up sounding the same.
Democracy is about choice.

The democratic *system* should reflect any political diversity, which is why we should have proportional representation at all levels and/or direct democracy, not single member seats.

This link is a act of bravery and we should know that.
It should be matched by Labor,regardless of the possiblity of a lost seat or two.
I note the anti Labor crew are out linking the greens, our ex voters to us.
And blaming every illness on that link.
Cute, and uninformed!
Liberals are a party that links its self to their pet dog the National Party.
They without a seconds thought took Katters vote and will use him Palmer and even one nation if they need to.
There! got me to take the focus away from a truth, nothing other than greens policy,s,gee they have heaps of them!, not as said one!
And of even more importance ACTIONS.
They promise anything knowing they will never have to deliver.
Banjo yes you will see the nose dive but remember the senate is not a full senate election.
We, all of us,must understand the senate once elected, takes two full terms of the lower house to be removed/face the voters.
IF Labor puts greens last we are watching their end come closer and we will again see majority gets to rule.
Watch for a double dissolution election in 2014.

Banjo having re read your question it deserves an answer.
I think the following.
Greens vote will be 7 point some thing.
Yes the five percent [currently counted in two party preferred polls] will vote Labor.
Some will just put a informal vote in, yes some greens are not middle class high income voters.
Some have always gave second preference to Liberals.
Banjo it is not until we get to the senate that greens get power and that the self wounding they are involved in will impact .
OF those three senate seats watch the South Australian one more closely.
But be Happy!~ at long last the party of idiot promises and wild threats is on the slide that leads to oblivion.
What ever my party says they will be last on both tickets for me.

Within both major parties are a diversity of religious, secular and environmental views that gain voters from every section of society. We choose on whom we believe who best represents us on the issues we strongly hold. The two major parties are not single issue focused.

You might want single issue parties with proportional representation that you have in the Senate. But that can stifle government if too many disagree with local representatives promises to their electorates.

Belly,
it will be interesting to see.

I have never seen a Green voter that preferenced the Libs, spose there are a few. Their HTVs always favoured the ALP. Watch to see if ALP formally puts Greens last.

the Green voters will then be really confused, the informal vote will go up.
