The greatest indigenous influence on the Jindyworobaks was literature which had been taken down by white folklorists and anthropologists. Written, as opposed to transcribed, indigenous literature did not appear in print until the 1920s when David Unaipon, a Christian from Point McLeay mission, South Australia, published a large body of work. Unaipon was publishing into the 1950s, by which time the Jindyworobaks were in decline. Unaipon was the sole published Indigenous Australian writer during their heyday, and indeed it was not until the 1960s that a second was published - Oodgeroo Noonuccal (Kath Walker). Unaipon, despite coming from South Australia, is not mentioned in the works of the Jindyworobaks, so it is hard to say how much of an influence, "Legendary Tales of the Australian Aborigines" was.
