Voice Referendum - do we need to limit the scope of representations made by the Voice?

If the Voice referendum succeeds in Australia, it will give the Aboriginal and Torres Strait Islander Voice the function of making representations to the Parliament and the Executive Government on 'matters relating to Aboriginal and Torres Strait Islander peoples'. Is this too broad and should it be limited to matters 'directly affecting' Aboriginal and Torres Strait Islander peoples? This video explains why the choice was made to avoid legal constraints and instead rely on political constraints to keep the Voice focused on matters of importance to Aboriginal and Torres Strait Islander peoples.
