Australia will head to a referendum later this year on enshrining the Indigenous voice in the constitution but confusion looks set to muddy the waters.

Wiradjuri woman and co-chair of the Uluru Youth Dialogue, Bridget Cama, said measures were being put in place to protect young Indigenous people's mental health in the coming months.

"There will be nasty things that come out of this," she said.

"This is only the beginning of the campaigning, it is a concern for all of us and I think it should be a concern for all Australians that this campaign might get nasty and there might be a lot of racism and racist things said."

In November, the Nationals announced they would be voting as a party against the voice, while Opposition Leader Peter Dutton has called for more detail on the proposal as the Liberal Party remains undecided.

Ms Cama said politicians have a responsibility to ensure the information in the campaigns is factual and centres on First Nations voices.

"This shouldn't be and was never envisioned to be about politics, politicians and their tribalism," Ms Cama said.

"This is about a better future for Australia."

Prime Minister Anthony Albanese said public office holders have a responsibility to not put up "furphies" and confuse voters.

"People should not put out disinformation and it will be combated where it can," he told reporters on Wednesday.

Mr Albanese said he was disappointed Liberal senator and former minister Jane Hume had not read the voice report by Tom Calma and Marcia Langton that went to the coalition cabinet.

"One thing is very, very clear: it isn't a third chamber, it doesn't have decision making-capacity, it is subservient to the parliament," he said.

"The fact that's been questioned, even though people know that no one's arguing anything other than that, is, I believe, unfortunate."

Mr Dutton refused to accept the voice would be an advisory body, saying the Langton and Calma report Mr Albanese referred to went beyond the concept.

"It talks about how it may choose other matters to provide advice on if the High Court interprets it," he told ABC 7.30 on Tuesday.

"I don't accept this proposition that foreign affairs or defence or education policy or any other policy affects Indigenous Australians more or less than what it does Australians living across the country more generally."

He said it was not unreasonable to ask for more detail.
