Well the ISIS brides will get the pension as well when they reach 67, and they won't have improved with age either. The two party ALP and Coalition system is on it's last legs, we're all seeing them for what they really are, ideological dictators, telling everyone else to sit down and shut up.
They rely solely on preference voting, not primary votes, to win seats. As such, all squares must be marked for votes to be formal. So the entire voting system is based on preferences, otherwise the system fails to work. Being mandatory to mark every square is dictatorship. Fill them all out, or your vote won't count.
