Falling support for the 'yes' vote in the upcoming Indigenous voice referendum is not denting Prime Minister Anthony Albanese's optimism about the prospects for its success.
The latest Newspoll, a survey of 2303 voters between June 16 and June 24, showed the 'no' vote at 47 per cent and the 'yes' side on 43 per cent.
Mr Albanese said he remained optimistic of the referendum's success and it would still be held between October and December.
He said referendums had not been easily won in the past - only eight out of 44 had been successful - but he was confident about the proposal being put to Australians.
"What we need to do is to make it clear and encourage people to look at the words that are being put forward, the very simple proposition," he told reporters in Canberra.
"This is now over to the Australian people."
Community organisations will begin hosting events in support of the voice as part of an effort to shift debate away from politicians.
Thousands of 'yes' events are expected to be held before referendum day.
The Yes 23 campaign will provide one-off grants of up to $15,000 to encourage further engagement and conversations about the importance of a successful referendum.
It's hoped the grants will assist regional and rural community groups to run 'yes' activities and forums.
Indigenous community organisations have also been encouraged to apply for financial assistance.
Yes 23 campaign director Dean Parkin said hundreds of community events supporting a 'yes' vote had already been held and the fund would support more conversations across Australia.
"It is about ensuring people, no matter where they live, can get informed about how a voice will give Indigenous people a real say on how to fix unique challenges across areas such as health, housing and education," he said.
There are more than 100 active community-based 'yes' groups and almost 10,000 volunteers.
More than 500 organisations, including businesses, faith groups and sporting bodies, have already confirmed their support of the 'yes' campaign.
Opposition Leader Peter Dutton maintains Australians are not ready to vote for the voice, as proposed, because there are unanswered questions about how the advisory body will work.
He stood by his party's decision not to support the 'yes' campaign.
"The prime minister has a deliberate strategy not to provide detail to the Australian public," he told reporters in Perth.
"There are many big-hearted Australians who want a better outcome for Indigenous Australians, but are ... wondering why the prime minister is keeping that detail from them."
Home Affairs Minister Clare O'Neil expected support for the voice to grow after debate moved out of parliament.
"We are going to win this referendum through millions of conversations that happen around people's kitchen tables and on their doorsteps," she told ABC Radio on Monday.
"It is very hard to get a referendum passed in this country and what we need to do now is (have) those millions of conversations that are going to switch hearts and minds."
