A 'Yes' vote to enshrine an Indigenous Voice to Parliament trails 'No' preference in all but two states, forecasting a failure to achieve a double-majority in the referendum poised to take place before November, according to latest polls.

In Newspoll data of 5417 respondents, between interviews and voters, published by The Australian on Monday, New South Wales and South Australia present as the only two jurisdictions showing slim preference in favour of the proposal.

Support for the 'Yes' vote does not tip over 50 percent in any state or territory.

'Don't Know' responses sit between seven and thirteen percent in each.

The latest survey displays individual stances across the country between May 31 and July 15.

The sample size between each state and territory varied between 372 to 1433 voters.

Queensland and Western Australia appear most resistant to the Voice, with just 39 per cent of respondents supporting a 'Yes' vote and 54 and 52 per cent returning a 'No' vote in each respectively.

They are the only two states where 'No' registered over 50 per cent.

Uluru Dialogue representatives and Statement from the Heart Architects Professor Megan David and Pat Anderson continued their Voice support campaigns in south-east Queensland across the weekend.

Federal Treasurer Jim Chalmers joined the pair for some public discussions.

Ms Davis called the region "a key corridor".

"Helping Queenslanders understand the history behind the Voice was what we set out to do and we achieved that with the group who travelled here today. We had conversations with local mob through a Yarning Circle in the morning (Sunday) and an event with the wider public in the afternoon in Logan Central," Professor Davis said.

"The Voice has a history of its own. It wasn't called for overnight, and it is something First Peoples support. The Uluṟu Statement was issued to the Australian people to walk with us in a peoples movement. We can't lose this conversation over these next few months."

Voice critic and 'No' vote campaign body Fair Australia leader Senator Jacinta Nampijinpa Price said "There are a lot more Indigenous Australians out there who don't feel like they've been represented through the Uluru Statement from the Heart" in response to polling numbers, according to AAP.

A successful referendum requires a double-majority to pass - meaning the majority of voters nationally, and a majority of voters in at least four of the six states vote 'Yes'.

The Prime Minister has said the referendum will take place in the last quarter 2023, with a date likely to be announced before the start of November.

Mr Albanese said it is to have votes recorded before the beginning of wet season.

"It is likely to be towards the front end of that period because of the wet season that occurs up in up in Australia's Far North. And we want to make sure that Aboriginal and Torres Strait Islander people can participate in this process," he told ABC Radio on Monday.

Amid the slide in support for the Voice, Mr Albanese said "there's a long way to go in this campaign".

Speaking on Sky News Sunday, No campaign leader Warren Mundine called the Voice an "elite proposal" with the 'Yes' campaign targeting boardrooms and companies rather than members of the public.

Last month, Mr Mundine told National Indigenous Times he had always been confident in the 'No' vote leading in all states and territories, and that "the largest number of (First Nations) people don't know about the Voice, or do know about the Voice, but do not understand it."

He reiterated the point on Sky News, and said he welcomed latest polling figures but will take them "with a grain of salt" before the public become more engaged with the referendum closer to voting date.
