Voice does it mean compensation and returning stolen land, page-4

You asked "What does return stolen land mean, How much compensation are we talking about?"

Go to UNDRIP and you will see that Article 28 states:

"Article 28
1. Indigenous peoples have the right to redress, by means that can include restitution or, when this is not possible, of a just, fair and equitable compensation, for the lands, territories and resources which they have traditionally owned or otherwise occupied or used, and which have been confiscated, taken, occupied, used or damaged without their free, prior and informed consent.

2. Unless otherwise freely agreed upon by the peoples concerned, compensation shall take the form of lands, territories and resources equal in quality, size and legal status or of monetary compensation or other appropriate redress."

Prime Minister Rudd ratified this in 2009.
