The government has conceded to a Liberal Party demand for pamphlets making cases both for and against the Voice to Parliament to be issued ahead of the referendum, in hopes of bringing the opposition onboard.
Finance Minister Katy Gallagher confirmed to Afternoon Briefing that existing laws requiring a pamphlet for both sides would be maintained, in a reversal of the government's decision last year to drop them.
Mr Dutton said pamphlets had been a precedent for referenda and needed to be kept.
"It was never sustainable for the prime minister to say to the Australian people that he wanted them to vote in the referendum and then only provide an argument for one side of the case," Mr Dutton said.
"It was frankly quite arrogant of the prime minister to believe he didn't need to provide details to the Australian people."
Senator Gallagher said Mr Dutton was "play[ing] politics again", but the government had made the concession in an attempt to work across parliament and reach a bipartisan agreement on the Voice.
Under the existing laws, supporting MPs are able to write a 2,000 word essay in favour of the constitutional change, while opponents are able to write a dissenting essay, which are both distributed by the Australian Electoral Commission.
Labor had sought to dump the pamphlet as it prepared arrangements for the referendum, saying it was no longer needed in the "digital age", with parliamentarians able to express their views to voters directly.
"The next referendum will be the first in the digital age," they said at the time.
However, the government has refused to fund "yes" and "no" camps for the Voice equally.
Mr Dutton said equal funding to both sides of the debate was "precedent" in referenda and should be continued.
The Liberal Party is yet to decide whether it will throw its support behind the Voice in a referendum, but its junior Coalition partner the Nationals announced last year their intention to oppose it.
The Greens decided on Monday that they would back the Voice after the exit of former Indigenous spokesperson and vocal Voice opponent Lidia Thorpe.
'It isn't woke': Liberal senator pushes for party to back Voice
Earlier today Liberal senator Andrew Bragg laid out five reasons that the Liberal Party should support the Voice to Parliament.
Senator Bragg wrote the Voice was "a liberal concept and a fair idea", and that "it isn't woke".
"It's not identity politics and it isn't a separatist agenda which denigrates Australia," he wrote.
Tasmanian Liberal Bridget Archer, another supporter of the Voice within the Coalition, said she believed many of her fellow MPs supported the proposal.
"I've talked to other colleagues who have certainly indicated that they are broadly supportive of a yes vote," Ms Archer said.
The Coalition remains sceptical of some details of how the Voice could operate, though those decisions would be made after the referendum and could be amended through legislation.
Senator Bragg wrote that a draft bill of the Voice should be presented alongside the proposed referendum wording, to give people the full picture.
"Without the detail, it will be impossible to set out how the Voice will improve lives and the nation overall," he wrote.
"At a minimum, we need to understand how the new local/regional/national Voice is going to interact with the government, and how this is going to help close the gap."
