Might encourage people w/ jobs who can't get to the polls to go and vote, but doesn't put unnecessary drain on their life.
They also should make voting day a national holiday, and give a tax deduction to companies who allow their employees to take as much time as they need to vote (given some lines can be hours long in places).

The damage he contributed to by supporting the repeal of Rudd's emission trading scheme and the mining tax was right up there with Trump's rollback of EPA standards and attacks on renewable energy. He promptly retired and went back to his mining interests once he got what he wanted.
His reappearance at the last election was bizarre and pointless, but may have contributed to the Liberals looking likely to only need to deal with Jacqui Lambie to pass any legislation in the Senate.
