@realjohnboy,
Quote:Am I correct in assuming that getting newly qualified 18 year olds to enrol favors Labor and the Greens?
You may well be correct about that, RJB.
But it's an important issue, too. John Howard "changed the rules" on enrollment deadlines to suit his own party's ends. So the day of the election date announcement was the last day people (not already on the roll) could enroll & be eligible to vote. Prior to that, people had 7 days grace to enroll after an election was announced.
Given that the party in power can (& usually does) choose an election date to suit it's own advantage, & sudden, "surprise announcements" are not exactly unusual, I think it's fair enough that potential voters have 7 days grace to get themselves onto the electoral roll.
Apart from that, as dp says, eligible Australians are
required to be enrolled. This gives them a last minute opportunity to meet their electoral obligations.
