The area is known as Nganmarriyanga, and incorporates several outstations with a total population of ~445 people. The main language in the area is Murrinh-patha, with English being the second language. The immediate area around Palumpa is the Wodidji clan’s land, with other clan groups from the surrounding homeland areas also residing at Palumpa.

The Palumpa community was established in the 1980s when Traditional Owners and missionaries from Port Keats developed a cattle station. The station was established to breed cattle to feed the local communities. It continues to operate in a limited capacity today.
