Ms Morris, who worked on the Voice with Aboriginal Lawyer Noel Pearson for more than a decade, gives an insight into the early days of negotiations for a Voice, and the enormous challenge of getting the 97 per cent of Australians without First Nations heritage to vote in support the 3 per cent who do.

Ms Morris pulls no punches on the way many of the No supporters conducted themselves. She reprints the foul-mouthed, all-caps emails from anonymous respondents, and looks at disinformation from the right-wing group Advance.

“I had to trawl through the comments under my posts and videos daily, deleting, hiding or blocking the coordinated onslaught of racism and hate,” she wrote, adding many posts attacked her South Asian heritage.

Ms Morris writes of the lost opportunity to rectify issues such as disproportionate labour participation and health outcomes.

“I can’t escape the conclusion that non-Indigenous Australians failed Indigenous people,” she wrote. “We failed them comprehensively on 14 October 2023.”

Ms Morris said that, despite the efforts of conservative politicians such as Matt Kean and Julian Leeser, the referendum’s failure highlighted a country divided.

“Maybe The Voice was unviable because the Coalition was so fundamentally closed to changing a system that is so badly failing Indigenous Australians,” she wrote.
