'Pine Gap' is a joint Australian-US defence facility based approximately 20 kilometres south-west of Alice Springs. But the land that the secretive military base is on is known by another name to Traditional Owners - Kuyunba. For the Hayes family, this is sacred land. That's why they wanted to lead the largest protest against the base in decades; approximately 300-500 people walked to the facility's first gate on Monday. Wyonna Hayes told NITV that Pine Gap is on Arrentre Country "without our permission". "Leading the protest today made us feel strong," she said.

"We can't give land to people to do things that are not right," she said. Wyonna explains that, "for so long, we've heard stories about what has been happening around the world in regards to the military base that's been put on our land without our permission, without our Elders' permission."Traditional Owners want land back, closure of the facility and compensationPart of the protest demonstration was the delivery of a letter from the Hayes family to the Pine Gap facility, which listed core demands. As Arrentre Traditional Owners, they want the land the base is on returned to them and the closure of the Pine Gap facility. They also have demands for compensation for "occupying Arrernte Country" and are concerned that the operations of Pine Gap have led to harm to Country itself. "We do worry about it because we don't know what they did for Pine Gap because there's a big facility and it's just all blocked up and fenced off," said Felicity Hayes. The protest followed a two day convergence in Mparntwe/Alice Springs, where plenary talks discussed the core demands from Traditional Owners.

Another form of compensation they have listed is for the facility to compensate families in the Gaza strip. For Wyonna, the protest is about fighting for the future of Arrentre Country and people. "We do have future plans for our next generation," she said. "We want let them know that we are still here, and we will always be here." NITV reached out to the Department of Defence, but they "do not comment on intelligence matters" including the Pine Gap facility.
