Australian Opposition Leader Peter Dutton has questions regarding the proposed Voice To Parliament before he offers support.

Peter Dutton wrote to Prime Minister Anthony Albanese a month ago with several questions regarding Albanese's Voice to Parliament referendum.

Professor Megan Davis, one of the leading authors of the Uluru Statement of the Heart has since confirmed it would be difficult to answer everything before a referendum is held.

Australian correspondent Murray Olds says the Oppsition's questions concerned who would be chosen to lead this, how much they would be paid, and where the location of this representative body would be.
