The prime minister has accused the opposition of walking away from helping achieve constitutional recognition for Indigenous Australians, as polling shows support for the voice has fallen.
Anthony Albanese said he was not deterred by polling indicating the 'yes' vote for the Indigenous voice had fallen below 50 per cent in every state.
Returning from the Garma Festival, where he advocated for the voice, he said the coalition had backed away from previous efforts for constitutional recognition, following the party's failure to attend the event.
"If it was somewhere where there were issues and problems, then (Peter Dutton) would have been first there but because it was a celebration of what's positive .... he was nowhere near it," he told parliament.
"What we saw between last year's Garma Festival and this year is a walking away from a process."
The coalition has pressed the government on setting up a Makarrata commission, which was part of the Uluru Statement from the Heart.
But Indigenous Australians Minister Linda Burney said the focus remained on establishing an Indigenous voice.
"We are not establishing a Makarrata before the referendum. Our priority is constitutional recognition through a voice," she said.
"We intend to get a successful vote."
Ms Burney did confirm $100,000 had been given to the National Indigenous Australians Agency to advance progress on the Uluru Statement.
The 'yes' case hasn't secured an absolute majority in any state, a Newspoll demographic analysis published by The Australian on Monday suggested.
It found those most likely to support the Indigenous advisory body were higher-income earners, the university-educated, renters and the young.
Those opposed to the voice included voters with no tertiary education, retirees, mortgagees and people who owned their home outright.
While the race was still close, a referendum based on current attitudes would fail to meet the threshold for success.
Opposition Indigenous Australians spokeswoman Jacinta Nampijinpa Price said the polling reflected people's wishes for more information about the voice.
"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," she said.
But former Nationals MP Andrew Gee, who quit the party because of its opposition to the voice, said large groups of voters were being alienated as a result of the coalition's position.
"I think the voice will succeed, I think we will get it over the line but if it does not there will be a real emptiness about what has happened," he said.
"I think it's a very short-sighted attitude (for the coalition) to take and I think longer term when the history books are written, history will judge them very poorly for it."
The referendum is due to be held in the last quarter of the year and the prime minister will announce the date in coming weeks.
