[1] The Undanbi occupied an estimated 900 square miles (2,300 km2) around the coastal strip along Coolum Beach and Moreton Bay, reaching down from Noosa Heads as far south as the estuary of the Brisbane River.
It extended inland, around 10 miles (16 km), to the area of Pine River, and the Glasshouse Mountains.
[7] They were distinguished from the Djindubari, who used charcoal and bees' wax to blacken themselves, by painting themselves with red ochre clan markings.
[8] By the mid 1840s, it is thought that many of the encampments in the Brisbane area arose from the Undanbi remnants of the Ningyningy and Djindubari who mustered there for blanket handouts and became notorious for their pitched battles, with the Turrbal clansmen under Daki Yakka, (known to the whites as the Duke of York).
[11] Their memory is evoked in the present-day place name for the town of Nimbi The Brisbane group of the Undanbi was said to have become extinct within a few decades of white settlement.
