Morgan self-published a book in 1990 titled Mutant Message Down Under, which purported to chronicle the journey of a middle-aged, white, American woman with a group of 62 desert Aborigines, the "Real People", across the continent of Australia.
[citation needed] According to the 90-page report published by the Perth-based Dumbartung Aboriginal Corporation, a survey of Aboriginal groups in Central and Western Australia failed to uncover any indication whatsoever of Morgan's presence in the area or of the existence of the "Real People" tribe.
They claim that Aboriginal groups believe Morgan's desert journey to be fabricated and that her book and teaching lack credibility.
Aboriginal people expressed anger that Morgan's false message is being accepted as fact by a naïve North American and European market and were extremely concerned about the resulting long-term implications for their culture.
The Aboriginal people engaging is this discourse are angry that Morgan's book continues to be promoted and sold widely, because they state it gives a false picture of their traditional cultures and of their current political and social status.
