Stakeholders have two weeks to tell the federal government how the terms of reference for a royal commission into the mistreatment of disabled Australians should look.
The consultation period on the government's draft terms of reference will close on March 28.
A public survey will be open until then, allowing Australians to provide feedback on the scope of the inquiry.
The government is proposing to investigate the violence, abuse, neglect and exploitation of Australians with disabilities, wherever it has taken place.
But Greens senator Jordon Steele-John, who was the driving force behind the royal commission, said redress should have been explicitly mentioned in the terms.
"A clear pathway forward for survivors of violence, abuse, exploitation and neglect must be included in any royal commission including prosecution, investigation and most importantly, redress," he said in a statement.
The commission would examine mistreatment in institutional settings, workplaces, schools, homes and in the community.
It would be applicable to all disabled people.
Prime Minister Scott Morrison says the federal government will fully fund the inquiry and he now has "letters patent" from all the states and territories to allow it to go ahead with the proper legal authority
Disability advocates are pushing for the royal commission to be called before an election, when the government enters caretaker mode and such an inquiry can no longer be established.
