Two questions about the Voice's wording, page-65

It's not nonses, Scott, I'm asking you a serious question. I'll structure it as a multiple choice to make it easier.

Indigenous Australians:

a) have been heard before, across the last 50 years, or;
b) have never been heard before.

So which is it? I'm going to keep asking it Scott until you answer it.

P.S. That's THREE times you've avoided answering a simple question.
