Aboriginal community leader Noel Pearson has warned the Acknowledgement of Country risks being overused, diminishing the significance of the practice.

Mr Pearson made the comments in an interview with 2GB.

"I think we're still in the learning phase … we ought to come to a consensus about when we use the welcome… I think we need to adopt a sensible approach to these things," he said.

"When someone opens a meeting, that's fine, but often I see every speaker then subsequently does their own welcome, it cuts into the meeting, I can tell you."

Mr Pearson's comments followed a discussion about the use of the Acknowledgement of Country by companies including Qantas.

"I think it's an important development but we in Australia are still learning, we've got to adopt a sensible approach to rituals in our public life," he said.

Mr Pearson also told 2GB Australians should not find the proposal of a Voice to Parliament disturbing.

"I think the average Australian, every Australian, understands the idea of an advisory committee, that is not a frightening concept," he said.

"This is our most sacred document as Australians, the Constitution, that's why we're so conservative about changing it, and that is how it should be. We should be very careful. Ninety-two words are going to change. We need to answer all the questions Australians are going to have about that," he added.

At the referendum on October 14 the public will be asked:

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?
