The fact that altering the Australian constitution requires a vote by the Australian people means that Voice referendum will become a vote about Australian nationhood.
This also means that the underlying question of the referendum is value-laden rather than strictly constitutional: what kind of nation does Australia want to be on the morning after the vote?
This discussion about nationhood is part of the logic of creating a winning coalition out of diverse constituencies that on their own are not big enough to secure a “yes” vote. But it should also be embraced tactically by the “yes” campaign to counter claims that the Voice is divisive.
