Notable examples have been made by many different Australian Aboriginal cultures, and in many cases are thought to be associated with spiritual ceremonies.
The appearance of the site is very similar to that of the megalithic stone circles found throughout Britain (although the function and culture are presumably completely different).
A very different example is found near Yirrkala in Arnhem Land, where there are detailed images of the praus used by Macassan fisherman fishing for Trepang, several hundred years before European contact.
In south-east Australia are the Bora rings, which consist of two circles of stones, one larger than the other, which were used in an initiation ceremony and rite of passage in which boys were transformed into men.
