This week we look at The Greens As the election nears, the Greens' polling is the highest in the party's history. So high, that pollsters and election analysts are predicting that they could end up with the balance of power in the Senate.

Apart from their views on the environment and asylum seekers, what else do they stand for? Greens leader Bob Brown will join Insight as we ask what all of this means for the next Government.
