Anthony Albanese has accused federal opposition leader Peter Dutton of attempting to "muddy the waters" and cause confusion around the Voice to Parliament.

Speaking in Adelaide on Thursday ahead of the 'Yes' campaign launch that evening, the Prime Minister pointed the finger at Mr Dutton for "doing nothing that would indicate" he is prepared to engage in bipartisan approach toward the proposal.

The federal National Party and the Northern Territory's Country Liberal Party have taken official stances against the Voice, while the federal parliamentary Liberals (led by Mr Dutton) are yet to make their position formally known.

"I've made my position very, very clear. I want to secure maximum support for this," Mr Albanese said.

"What we have from Peter (Dutton) ... I think people can draw their own conclusions.

"It's not like it's very subtle.

"It's very obvious and I think it contrasts with the goodwill that is required here."

Mr Albanese said the Voice is about Aboriginal and Torres Strait Islander people, "not for politicians" and challenged repeated claims from the coalition on a lack of available details on what it will look like in Parliament.

He reiterated it would serve only to inform decisions within parliament, and not have the ability to override legislation.

"It shall make representation on issues which impact Aboriginal and Torres Strait Islander people … The functions and activities of the voice will be determined by Parliament," he said.

"The reason why it needs to be legislated by the whole of parliament is (because) over a period of time that legislation will change. It's subservient to the Parliament.

"The Voice is about two things. Two things only. It's about recognition of Aboriginal and Torres Strait Islander people in our nation's birth certificate, and it's about consultation.

"The Voice will be able to have consultation on matters that directly affect Aboriginal and Torres Strait Islander peoples."

Mr Albanese urged all areas of government to get behind the proposal and end the long wait to see the initiative enshrined.

At a community BBQ in Sydney on Saturday the Prime Minister announced Australians can expect to cast their vote between October and December this year and issued a plea to incumbent politicians "not to miss this opportunity" for change.

"(The Voice) will send the message to the world that we're a mature nation, that we're prepared to come to terms with our history and who we are, that we're proud of who we are," he said.

"This is an opportunity to unite our nation and I say to those in positions of political leadership do not miss this opportunity this time."
