Gavin King chats with Dean Parkin, Campaign Director of the Yes 23 Campaign, to better understand the "voice to parliament" debate that is dominating headlines across Australia.

This year, Australians will vote on a referendum to change the constitution and establish an Indigenous advisory body to consult with lawmakers about policy decisions.

The "No" campaign (those who oppose the constitutional change) argues that more details are needed about the application of a new advisory body and what its true function would entail.

The "Yes" campaign argues that constitutional change is about the official recognition of Aboriginal and Torres Strait Islander peoples within Australian law.
