The one thing you are fogetting is that Tasmania was the First place in the world (I am pretty sure) to have Greens candidates elected to parliament. They are not 'copy-cats' of European models.

As for the nasty assessment of their predecessors, remember that originally they were activists who decided that it was worth working within the system as well as outside. The first elected Greens MPs still behaved like the activists they were. Over time the party has realised to have more influence they must behave more like politicians. It is a natural progression.

also don't assume that forestry will be a background issue, the one thing that voters respect about the Greens is that they actually stand for something - and stick to it. They don't flip and flop about with their policies depending on the mood of the poll of the day like the two major parties do.
