I've been doing a bit of looking around at Australian politics on the net. I only have two politicians blogs in my blog roll - and I haven't had anyon yet tell me of better ones.
But one of the sites I have found is Oz Politics which is both a blog and as well a web site with a wealth of info. One of the interesting features is the test where the user gets given a series of questions from which an inference is drawn about the respondants position on three dimensions and an assessment of what party best suits you. I encourage you to do it if you haven't already, and if you have or do post a comment about it here.
You can see my results here. Nice to know I belong to the right party! However it is an intriguing result that a lot of ALP respondants are "assigned" to the Dems and Greens by the test - confirming my view that the modern ALP really is a conservative party.
It is a pity therefore that Oz Politics doesn't devote any space to these other parties in its guide section.
