This is a good, if long article. This section is worth noting: Advance Australia, "boasted that it ran contradictory messages for different audiences during the Voice referendum campaign.
It said its main campaign, Fair Australia, told people that the Voice was divisive and went too far, and should be voted down; while its Not Enough campaign was specifically targeted at progressive voters in urban areas and said that the Voice didn't go far enough, so it should be voted down."
