 FACT: Quigley and Crazy Cora are taken to a camp by the native  Aboriginal people. There they chant and play a Didgeridoo. In this  part of Australia, Western and Central there are no didgeridoos. The  Yirdaki and Mago Didgeridoo are endemic to only Arnhem Land. In the  Western part they use Mago, in the North East part they use Yirdaki.  This is at the very northern part of Australia, in a small delimited  area. When this scene was cited to have taken place none of the the  central and western Aboriginal Australians, namely in the desert,  used a Didgeridoo in playing music. Only in later times has it  spread more though out Australia.
