Traditional land owners from Far North Queensland and the Torres Strait will have their say on the Indigenous voice when an inquiry into the body resumes.
The third hearing of the parliamentary inquiry into the voice to parliament and executive government will be held in Cairns on Wednesday.
The committee is examining the proposed constitutional changes and the question that will be taken to the public before the terms of the referendum are locked in by federal parliament.
Among those giving evidence at Wednesday's hearing will be Torres Strait Island councils, along with traditional owner groups from Cape York and the Torres Strait.
Comittee member and Labor senator Nita Green said it was critical to hear the thoughts on the voice from local communities.
"No member of the committee is leaving any stone unturned when it comes to seeking the right evidence and the right support and the right advice," she told Sky News.
"We're doing that and we're doing it diligently because we know how important this committee is not only to the Australian people and to the parliament but to all of the people who care about the voice."
Australians are set to vote in the referendum on the voice between October and December this year.
The inquiry examining the voice started last week and has held hearings in Canberra and Orange in the NSW central west.
"What we're asking people and talking to people about in those committees about what they think about the legislation ... what they think about the wording, and does the wording give effect to what they want to see a voice to parliament do and what it can achieve," Senator Green said.
Prime Minister Anthony Albanese said the solicitor-general's view on the voice would be released soon, accusing Opposition Leader Peter Dutton of running scare campaigns on the body.
"Peter Dutton can continue to wallow in his negativity, I think that Australians will judge him for that," Mr Albanese said on Tuesday.
The Liberal Party has called for a legislated but not constitutionally enshrined voice process involving representative local and regional bodies.
"We've been clear, we don't want an elitist model, which is what the prime minister is proposing. It's a Canberra voice, it's not going to represent the views of those local communities," Mr Dutton said on Tuesday.
