Politicians campaigning for an Indigenous voice to parliament have taken to the streets of the nation's capital to thank volunteers as the referendum date approaches.
Prime Minister Anthony Albanese, senior Labor figures including Finance Minister Katy Gallagher and Independent senator David Pocock met supporters in Canberra on Saturday morning.
Mr Albanese spruiked what he called a powerful and uplifting advertisement for the 'yes' campaign which is set to be released on Sunday.
"What I get, wherever I go around the country, is that there is momentum behind the Yes campaign," the prime minister said.
"This is a process that has been under way since well before the election of this government.
"Indeed, under the Abbott government, Turnbull government, Morrison government, there were processes."
He also took aim at what he described as "fear campaigns" about the voice.
"This campaign is going to be won by one-on-one conversations with people, making sure that the fear campaigns which are there (are) no more real than the fear campaigns that were there about the Apology to Stolen Generations, about Mabo, about native title, about marriage equality, about all of these issues."
Supporters and opponents of the voice are mobilising ahead of the October 14 vote to recognise Indigenous people in the constitution.
The proposed voice to parliament will be able to advise parliament and the executive government on issues affecting Aboriginal and Torres Strait Islander people.
The referendum's success depends on majority support across the country and in four of six Australian states.
The question to be put in the referendum is: "A Proposed Law: to alter the Constitution to recognise the First Peoples of Australia by establishing an Aboriginal and Torres Strait Islander Voice. Do you approve this proposed alteration?"
If the referendum vote is successful, the government will then design the specific form of the voice, which will be implemented via legislation passed by and debated in parliament.
