Yes campaigner Kristie Parker, an adviser to the Uluru Dialogue, said it was hypocritical for Mr Dutton to complain about the cost of the Voice referendum, while also proposing to hold a second referendum.

“This demonstrates that the opposition leader is not listening to Aboriginal and Torres Strait Islander people, who have very clearly asked for something that will change our lives,” she said.

“Some people have said the referendum is an expensive exercise, and yet here we have the opposition leader, proposing to spend the same amount of money on something that would not change lives.”
