Only three?! 
If I have to choose:
6 - Freedom of speech
7 - The “why” of Pirate Party Australia
9 - Civil liberties in the virtual world
6 and 9 are topics that I am personally very interested in (and I’m sure most PPAU members feel the same way).
I’ve enjoyed reading the commentary on 7 from Frew and others - it would be interesting to hear more people’s thoughts on this at Congress.
(sidenote: discourse handles out-of-order numbered lists very strangely!)
