The Traditional Owners of the the lands in the Ipswich region including the Rosewood Scrub are the Clans that identify as being a part of the Yagara/Yugara Language Group (the Jagera, Yuggera and Ugarapul People).

Information from Desmond Crump
There are a couple of references for Warpai group which refers to them as a subgroup/clan of Yuggera. Thomas Petrie’s reminisces is the earliest source. It is also referenced in the original indigenous land use agreement with the Ipswich City Council as well as the local dance group Nunukul Yuggera.

If a spear was not the correct shape when being made, it could be straightened by heat and then bent properly over the head. The Ipswich, or ” Warpai ” tribe, made spears from rosewood (” bunuro “), and these were sometimes exchanged for others; the Brisbane tribe valued them greatly. Before a fight, quantities of spears were made ready.
