Both the question and the draft constitutional amendment that will be put to voters in this year's referendum on an Indigenous Voice to Parliament are expected to become more certain later on Thursday.
On Wednesday evening, Prime Minister Anthony Albanese met with members of the Referendum Working Group — which is made up of representatives of First Nations communities from around Australia — to iron out an agreed position on the wording.
It is expected the PM will put that proposal to cabinet this morning.
Mr Albanese put forward draft wording for both the question and the constitutional amendment in the middle of last year.
The Referendum Working Group has spent months forming a view on the wording, including weighing-up additional suggestions from the government and other experts.
Its members had considered ideas such as removing the words "executive government" from the draft amendment, but that suggestion was rejected.
Another suggestion — put forward by the Attorney-General Mark Dreyfus — sought to add words to the draft amendment aimed at reducing the risk of future legal challenges but that, too, was rejected.
Late on Wednesday, working group member Megan Davis told a press conference agreement with the government was imminent.
"We are so close, so close to finalising our advice, so the government can introduce the Constitutional Alteration Bill to parliament next week," she said.
"So close to doing what grassroots communities across the country have asked for.
"So close to taking the next historic steps towards a successful 'Yes' vote."
The wording could yet change further, as it still has to be considered by parliament.
On Thursday morning Mr Albanese confirmed he would have more information about the outcome of the working group's meetings later in the day.
"It's incredibly constructive and I give such praise to the leaders of Aboriginal [and] Torres Strait Islander peoples who have done work in a way that is so patient," he said.
"This is a very modest request to be recognised in our constitution after 122 years."
Next week, the Constitutional Alteration Bill will be introduced to parliament. It will contain the proposed wording, and will be referred to a parliamentary inquiry.
That will allow further public debate on the wording, before the bill is passed and the question and amendment are put to the public later this year.
Procedural legislation passes Senate
Legislation outlining how the referendum will operate passed the Senate on Wednesday night after the government struck a deal with the Coalition.
The Referendum (Machinery Provisions) Amendment Bill will modernise the Referendum Act, which has not been used since the unsuccessful referendum on forming a republic in 1999.
Labor will allow an official pamphlet to be distributed across the country outlining the respective "Yes" and "No" cases, with a "neutral" civics campaign to be run nationally to ensure voters understand the referendum process.
It means that the same financial disclosure and transparency requirements applied to elections will be in place for this and future referendums.
The government had earlier rejected a request from the Coalition to provide funding for both the "Yes" and "No" campaigns.
