what do you want to know? it hasn’t happened yet so we don’t know what the precise outcome will be.
constitutionally what is accomplishes is enshrining in the constitution a body called the voice which has the right to address Parliament on matters relating to aboriginal and Torres straight islander people.
what this stops governments doing is disbanding advisory councils etc which they have done repeatedly.
The statement from the heart (https://ulurustatement.org/the-statement/view-the-statement/) specifically requests it. you can read about what they hope it to accomplish here: https://ulurustatement.org/the-voice/what-is-the-voice/
What have you googled and found unsatisfactory?
we don’t know what the precise outcome will be.
Partially true but, as I have said in my reply to this comment, the proposed constitutional amendment contains this line
In recognition of Aboriginal and Torres Strait Islander peoples as the First Peoples of Australia
which is clear symbolic recognition of the importance of Indigenous peoples and their culture to the history of Australia. Regardless of what the advisory body looks like or achieves, constitutional recognition would be a clear positive outcome in the result of a Yes vote. It is important to many Indigenous Australians, but it should also be seen as important to all Australians as we continue to mature as a nation and move forward from our bloody colonial past.
