The Araguaia Avá-Canoeiro who have been contacted live in the Canoanã Indigenous Post, in the Araguaia Park Indigenous Land (with an area of approximately 1,395,000 hectares), on the Javaés River, on Bananal Island, in the Southeast part of the State of Tocantins. The park occupies the island's Northern third.

The Avá-Canoeiro still without permanent contact live in the North of Bananal Island, in the areas of the Araguaia Indigenous Park and the Araguaia National Park. Funai started in 1991 the process of clearing off the Indigenous Park of its non-Indian occupants - 'retireiros' (people who milk cows) and small cattle raisers. Of the approximately 900 settlers and invaders, 208 are still there, most of them in the Southern part of Bananal Island.

The process of regularization of the lands of the Tocantins Avá-Canoeiro began with a directive signed by Funai's president on April 8, 1985, which interdicted an area of 38,000 hectares in the municipalities of Cavalcante and Minaçu, in the State of Goiás. The directive sought to preserve the areas where the Avá-Canoeiro moved about and the area then occupied by the group who had made contact in 1983. A directive issued by the minister of Justice on October 2, 1996, declared the Avá-Canoeiro Indigenous Land of permanent possession by the Indians. The area, however, is still occupied by a large number of non-Indians, who want to be compensated before moving away.
