The false dichotomy rhetoric of “they’re better than the other party” is just insufferable, and the US has shown us how the two-party duopoly plays out.
Just make sure you preference Labor ahead of the Coalition. That's the risk of "both sides" rhetoric, although I would hope that most people here understand this.
Investigate your candidates.
Agreed. The guardian have a short summary on the minor parties although it could stand to take slightly more of an opinion on some of the parties.
There's often this revisionist history about things as well. Labor wouldn't negotiate with the Greens over the original ETS, and the Greens get blamed for it not passing. Only a few years later they work together and make a better policy (the carbon price). Abbott comes in and tears it up. Current Labor supporters either conveniently forget this ever happened, or they somehow argue that Abbott would have teared up the carbon price but not the ETS.
