The Freedom Movement, which was born at the Freedom Summit at the Old Telegraph outside of Mparntwe (Alice Springs) last November, will gather once more from September 11 to 13.
Members of tribal nations, including Arrente leader Rosalie Kunoth-Monks, will be present.
Narungga Elder Tauto Sansbury said: “We need to show a united front on this important issue of sovereignty in our country, which has been railroaded by the Recognition campaign, a diversion from the real issues, and will not deliver for all traditional owners.”
