Prime Minister Anthony Albanese has revealed the wording of the question to be put to the Australian public in the upcoming referendum on an Indigenous Voice to Parliament.

Flanked by the Referendum Working Group at Parliament House Thursday morning, Mr Albanese said "the question that Australians will be asked at this year's referendum is a very simple one".

"Today we take a very important step forward on that journey," he said.

"After many months of careful consideration on the draft formal words that I presented at Garma last July, the Referendum Working Group and the government have agreed on the provisions that all Australians will vote on in this year's referendum."

The wording of the question reads:

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?

In announcing the question set to be posed to the public later this year, Mr Albanese paid tribute to the work of the Referendum Working Group.

"This moment has been a very long time in the making," the Prime Minister said.

"They (the Referendum Working Group) have shown such patience and optimism through this process, and that spirit of cooperation and thoughtful, respectful dialogue has been so important at arriving at this point in such a united fashion."

More to come.
