I reckon the Greens will win more seats this time round.
You know, rather than pulling statements out of your arse, it would be a good idea to back up that rhetoric with a bit of logic... No, I don't think the Greens will do incredibly good (at least not better than the position they are in at the moment)... In my opinion, their popularity has all but peaked...

Expect that to correct to the 2013 election levels for the Greens as more people become clear on who they will vote for... I'd call it if I was LNP ASAP, they would still win...
When you think about the big picture as well, you have a political party with about 10% of the total vote with the capability to bring the Senate to gridlock (which is what they have been doing with the help of the ALP and independents)... If you are talking about a power struggle, you cannot top that in terms of a power imbalance... If anything, the position they are in at present is one that I think many politicians would envy...
The Greens would fizzle if they were to gain the momentum which would make them a major political party... especially in a country that, lets face it, is extremely conservative...
