Opposition Leader Peter Dutton has vowed to continue to meet with Indigenous leaders helping to shape the looming Voice to Parliament referendum.
The referendum working group met with Prime Minister Anthony Albanese, Mr Dutton and Shadow Minister For Indigenous Australians Julian Leeser on Thursday afternoon.
"The Liberal Party will continue to be constructive and Mr Dutton has committed to further engagement with the referendum working group," a spokesperson for Mr Dutton said after the meeting.
Constitutional lawyer Megan Davis, a member of the working group and co-chair of the Uluru Dialogue, said while she welcomed bipartisan contributions, it would ultimately be a matter for the Australian people to decide.
"Bipartisanship is something we would welcome. We welcome Peter Dutton's commitment to further talks on the Voice referendum," she told reporters.
"The Australian people will determine the outcome of this referendum, not politicians.
"The constitution is the people's document. Politicians can't change it. Parliament can't change it. Only you, the Australian people, can change it."
Professor Davis, flanked by working group members, didn't take questions from reporters.
But she said the group was close to finalising the wording of the proposed change to the constitution, which would go to government next month.
For a referendum to occur, the parliament must pass a bill that outlines the proposed change to the constitution.
The referendum must then be held no sooner than two months, and no later than six months, after the bill passes the parliament.
"The working group has made significant progress on the referendum question and the constitutional amendment to be put to the Australian people," Professor Davis said.
"Final recommendations will be given to the government in the next month, with the introduction of the constitutional alteration bill on track to be introduced to Federal Parliament in March."
Mr Leeser described the working group's presentation as comprehensive but said he still had questions that needed answering.
"I didn't learn anything today that I didn't already know," he said.
Mr Albanese has vowed to hold the referendum in the scond half of the year.
