Lawyers and social workers perhaps, but have you thought about the political benefits of changing the constitution in a manner whereby they have succeeded in removing the crown from one particularly large state, ie, WA whereby it renders individual votes worthless, converting them into school-voters this and then preceding to fill this state with proxy-voters as it fills up and then preceded to vote away the rights of those more informed?
As they precede to turn WA into a quarry and vote bank.
Last time they held a referendum, monarchists won by a relatively small margin, I think 5%/7%.... so imagine how many they have immigrated since 1999, this and are filling WA up with.. it wont take much to push them across the line particularly now WA voters don't have the same rights, vote wise as the rest of Australians now they have removed the crown from the state.
Recall when Gillard was charged with treason, (albeit the charges didn't end up sticking as they changed the laws after having changed the constitution making what they did legal after the fact)....
This is what the ALP are doing... filling our country up with school-voters for their political advantage.

Give them your finger, and they'll take your arm.
Basically, ALP GALP wont be happy until they have immigrated enough to get them over the line (vote wise) in order for us to like it or not, unwittingly vote for a republic.
Far from democratic when you think about it.
