A deal has been struck to move ahead with the legislation necessary to set up the referendum on the voice to parliament.
The opposition has agreed to support the bill in the Senate with amendments, including a physical pamphlet outlining both the "yes" and "no" cases and some funding changes.
There is also set to be official recognition of "yes" and "no" campaign organisations, with the opposition pushing for "an appropriate level of funding in relation to those organisations".
"I'm on the public record as saying I don't wish to see many millions of taxpayer dollars committed to massive television advertising campaigns," Liberal frontbencher Simon Birmingham told the Senate.
"Where if government funds are to be spent, they should be spent solely in relation to the conduct of the referendum, in relation to the turnout of the vote in relation to the basic facts that apply to this referendum.
"Not in terms of favouring one side or the other through this campaign."
The Greens have put forward amendments to increase access to voting, including on-the-day enrolments, an expansion of phone voting and greater polling access in rural communities.
The legislation will sail through the Senate with the support of the opposition, but the government will need the 11 Greens and two crossbenchers to vote in favour of the bill if the coalition opposes it.
Senator Birmingham says the opposition was pushing to have integrity, fairness and respect during the debate.
"The fact that there will be a proper process for proper arguments to be laid out in a considered way ... hopefully, can ensure that the debate is conducted with the greatest degree of respect, with the greatest degree of consideration for opposing views," he told the Senate.
A second bill which sets out the wording of the constitutional change is expected to go to federal cabinet in coming days before being introduced to parliament next week.
