Yes23: This referendum is about straightforward ideas and practical solutions, page-3

"4. Over 80% of the Aboriginal and Torres Strait Islander community support this proposal."

There's probably an asterisk at the end, stating that this was from a poll of 600 ATSIs conducted in November 2022 by the Australian Labor Party.

Even if it were true (which it probably isn't, as other polls have shown the support down to 60%), this would mean 4. could be rephrased as:

"4. Up to 150,000 Aboriginal and Torres Strait Islanders are against the Voice."
