Barnaby Joyce refuses to answer whether he supports changing Australia Day date despite Sunrise host Nat Barr asking five times

Fractures in the No campaign over what would happen if the Indigenous Voice to Parliament were rejected made for some bizarre scenes on Sunrise.

Nationals MP Barnaby Joyce failed to back No leader Warren Mundine on Monday morning, a day after the Bundjalung man suggested a no vote was the best way to reach a treaty and supported changing the date of Australia Day.

Mr Mundine – who last week reiterated that he would seek a position on The Voice if the Yes vote was successful – made the comments on ABC’s Insiders on Sunday.

Australians will vote on October 14 in the first referendum since 1999, in less than four weeks.

The comments are at odds with much of the conservative No campaign, which warned that Voice would be a gateway to “expensive” treaties.

Mr Mundine threw his support behind changing the date of Australia Day in comments made on the ABC’s Insiders program on Sunday.

And, earlier this month, it was revealed no volunteers had been instructed to exploit fear and warn Australians that The Voice would seek to change the date of Australia Day.

Asked five times whether he shared Mr Mundine’s aspirations and views, Mr Joyce did not respond on Monday morning, instead calling on Australians not to change the “status quo”.

“I can tell you that fully following through on the Uluru Declaration means yes to the referendum, yes to the treaty,” he told Sunrise host Nat Barr.

He was interrupted by Barr, who asked him pointedly: “Do you support Warren Mundine, one of your fellow non-believers?”

Mr Joyce responded: “I’m stating the obvious where we are right now, we’re living in the status quo and it’s been incredibly beneficial to Australia.”

Leading yes supporters and senior government ministers have seized on the split.

Mr Joyce’s colleague, Environment Minister Tanya Plibersek, sought to call out the Nationals MP for not taking a clear position on Mr Mundine’s statements.

“Why doesn’t Barnaby answer the question,” she said.

Mr. Joyce was interrupted by Natalie Barr during an interview Monday morning, who asked him pointedly: “Do you support Warren Mundine, one of your fellow non-believers?”

Mr Mundine’s comments are in direct contradiction to those of his fellow No campaigner, Senator Jacinta Nampijinpa Price, who in a speech to the National Press Club last week said she feared the treaty and reparations for indigenous peoples are Voice’s top priorities.

Senator Nampijinpa Price said she opposed treaties because “you can’t make a treaty with your own citizens.”

In comparison, Mr Mundine said he supported treaties with local indigenous groups to protect heritage and culture, but opposed any national treaties with indigenous people.

Asked if there was a contradiction between his views and those of his fellow No activists, Mr Mundine replied: “That is correct. I’m still strong on that.

“I know people on my side disagree with me on these two issues: the treaties and the date change.”

As the No campaign seeks to recalibrate after differences of views emerged, the Yes campaign was buoyed by the more than 200,000 people who gathered across the country to participate in March for Yes rallies Sunday.

Australia’s Indigenous Affairs Minister Linda Burney told the Melbourne crowd – between 30,000 and 60,000 people – that it was “truly overwhelming” to see so many people turn out.

“To know where your heart is, to know where your mind lives. And that you, like us, want to seize this opportunity to move this country forward together,” she said.

“Each of you can help answer the call of generations of Indigenous people to be recognized and to be heard.

“For 65,000 years, Aboriginal and Torres Strait Islander people have spoken 363 languages, but no voices. In 27 days you have the power to do something.
