Yidaki have been used instrumentally throughout ceremonial practices for millennia. Made from the Gadayka (Stringy Bark) or Gunurru trees that have been hollowed out by white ants and then cut to size and cleaned out to give the desired sound. 

These are used for Bungguls (ceremonies), at Dhapi (initiation) and Maradjirri (exchange rituals).

JB’s features his totems Narrgi’ṉarrgi (possum- sugar glider) and Djarrka (goanna).
