Lead campaigners for the 'yes' and 'no' cases are making their final national pitches before early voting begins next week. Today, the intellectual force behind the Indigenous voice to parliament, Noel Pearson, made his case in his address to the national press club in Canberra. Independent Senator Lidia Thorpe opposes the voice. She gave a response to Mr Pearson's arguments speaking with Greg Gennett from Melbourne airport.
