Newly arrived migrants and refugees are more likely to support the Voice to Parliament the more they understand the upcoming referendum.

A survey conducted by migrant settlement agency Adult Multicultural Education Services (AMES) Australia found awareness and understanding of the Voice was low, with 67 per cent of respondents either not aware or largely unaware of the proposal.

75 per cent were not aware it would mean a change to the constitution.

150 people from 30 countries studying English or accessing migrant or refugee settlement services and had been in Australia for less than five years took part in the survey.

50 per cent said they were in favour of the Voice in general, with 40 per cent undecided.

Among a group of thirty, support jumped to over 80 per cent after an explanation session.

Syrian refugee Norma Medawar Chamous said she supported enshrining a Voice now with a better understanding of what it is.

Ms Medwar became an Australian citizen earlier this year.

"When I learned more about some of the disadvantages indigenous people in Australia face, I realised there was a need to address their specific issues," she said.

Being informed on Australia's recent history came as a shock.

"Learning that Aboriginal people could not vote before 1967 was a surprise. As the original people in this land who have been displaced by settlement, we should do more to support the progress of Indigenous communities," Ms Medawar said.

Ms Medawar said accessing credible information had been difficult, with misinformation present in her online engagement.

Speaking in an Australia Institute seminar in July, Uluru Dialgoue co-chair and Statement from the Heart architect Professor Megan Davis said there has been a "real problem with disinformation and misinformation".

"How do Australians make informed decisions if what they've been given is not accurate information," she said of some online rhetoric.

On Wednesday Australian Electoral Commissioner Tom Rogers said culturally and linguistically diverse information would be made available in the lead up to the referendum.

AMES Australia CEO Cath Scarth said the survey was indicative of the need for facts to be properly communicated, but placed some onus on the public.

"The Voice is an important referendum that would give Indigenous Australians a say on issues that affect them and have the potential to positively impact thousands of lives," Ms Scarth said.

"AMES are doing what we can to disseminate information but we think this should be a whole of community effort.

"It's important that everyone eligible to vote in the referendum understands what The Voice means, what it is seeking to redress and the difference it might make in people's lives."

Australians will head to the polls for the first referendum in over two decades on October 14.

Campaigns on either side have officially launched following the announcement, with a six week push ahead of them.
