 The Ngadjuri used petroglyphs, body art, and other art forms to express their culture and beliefs.and examples of the first can be found at Firewood Creek, just a little to the northeast of Burra (in Ngadjuri, this place is known as Kooringa).Parallel striations (lines) are a very familiar theme, but other familiar features of Indigenous Australian art, such as hand prints, and kangaroo and emu footprints were also used.
