Katter's Australia Party is a rather interesting case. When I started reading through their policies I got the feeling I had read them before, and not just at the last election. Indeed, when I went back and reviewed the policies of CountryMinded, there were large chunks of the policies that were word for word identical.
I asked both parties about this on twitter and got an answer that exposed some of the behind the scenes action between the two. As it turns out, the founder and lead candidate for CountryMinded was formerly a candidate for Katter's Australia Party and was the main person who wrote up the policies for Katter's Australia Party. Since last election there's been a falling out and thus CountryMinded was born. And apparently neither group has felt they should abandon the policy documents as they are. Thus in terms of policy, I don't have much to say about them beyond what I said previously about CountryMinded.
I'm not sure I agree with the CountryMinded folk that they can just use the exact same policies with just a few minor cosmetic changes when they left, because just as I can't take my employers intellectual property with me when I leave to a new job, you can't take a set of policies you wrote for one party with you to another.
