The “smart people of Canberra” can’t close the disadvantage gap that divides Indigenous and non-Indigenous Australians without a Voice to Parliament, proponents of the body claim.

Liberal MP and Yes campaigner Julian Leeser said governments would continue to do a “really bad job” at fixing the disadvantage experienced by First Nations peoples without better consultation.

“One of the key reasons that disadvantage hasn’t been addressed properly, is because smart people in Canberra will come up with ideas that don’t actually match what’s happening on the ground. And the purpose of the Voice is actually creating better public policy on the ground,” Leeser said.
