One very important thing to not forget about in this thread about Aussie Dreamtime.
Song Lines
{START EXPERT KNOWLEDGE}
Briefly, large areas of the country are roamed in a nomadic fashion. The sites, and the paths between are connected with songs (perhaps another culture would call them chants) which have magical power, and hold together the structure of the world this culture lives in. The stories often have some connection to the Dreamtime. Many are about the creation of the landscape the group moves around in. Also the Painted Art (now being done in [semi]permanent media, and which used to be done in the sand - like Mandellas) is often like a cultural map of the surroundings, or may tell creation stires of the landscape. It can also show where important things like water and food exist in a particular area.
These things are all parts of each other, and really mean more when taken as parts of the whole.

That's all I know, one of the many things I know almost nothing about.
