I voted for them last time, and I'm voting for them again. Be aware that voting for the sex party is almost a donkey vote in all but Victoria though. Make sure you vote below the line.
I've always wondered about people's reactions (or lack thereof) when this was first put into practice. It seems to me that the results can only be negative. It just encourages lazy & uninformed voting and perpetuates the problem of money in politics -- the more $$ you have, the more signs with your name on them you can buy; the more signs you have, the more people have heard of you, and the more blind votes you get.
If you do know the names of the members that comprise a party, then you can just as easily vote for the members specifically by name (and if you're too lazy to do this then how did you manage to haul your carcass to the polling booth?) If you're so ignorant that you don't know the names of the members that comprise a party, maybe you shouldn't be blindly casting a vote for them.
