A large sandstone rock art site, Marra Wonga, near Barcaldine, central Queensland, is the focus of this paper. This 160-metre-long rock shelter is estimated to have over 15,000 petroglyphs, which are mostly animal tracks, lines, grooves and drilled holes, as well as 111 hand-related and object stencils. There is also a cluster of human-shaped foot petroglyphs on the floor of the shelter, some with six or more toes. Unique compositions on the shelter wall include seven large, engraved star-like designs with central engraved pits and large, engraved snake-like designs running across and through other petroglyphs. We describe and discuss some of the features of Marra Wonga from archaeological (etic) and ethnographic (emic) perspectives, especially in terms of the significance of a petroglyph of an anthropomorph, seven star-like designs seemingly made as part of a composition, the large snake-like designs, and six-toed human feet. Today, Marra Wonga is a teaching site used to tell important cultural stories that are connected to many other places through the imagery and Dreaming Tracks, as well as a tourist destination managed by the Yambangku Aboriginal Cultural Heritage and Tourism Development Aboriginal Corporation (YACHATDAC), with whom we partnered for this research.
