Aboriginal Weapons
Aboriginal weapons are used primarily for hunting. The most known Aboriginal weapon for hunting is the Aboriginal boomerang, but Aborigines used and still use a wide range of hunting tools. Apart from the boomerang they use spears for hunting and fishing. (Read about spear making here) Aborigines use the woomera (spear-throwing device) to overcome great distances with a spear.
Settling differences
There is an Aboriginal law for everythings. It regulates the life in a community, marriage, ceremonies, punishment and the fighting. Yeah, the are rules for fighting, too. Aborigines have never fought for land or food. There is no reason for that, because the ancestor beings entrusted each tribe with land. Aborigines are the custodians of the land not the owner.
However, in case a member of one tribe accuses somebody of another tribe a tribal fight could have taken place. Often jealousy over women, long-harboured grievance or accusation of murder was and is the reason for a tribal fight. Suspicions often lead to accusations and in some cases to a full blown tribal fight. Since tribal fights were a common part of Aboriginal life, Aborigines spend much time to make weapons.
In a tribal fight men would line up with their spears, boomerangs and shields. Remarkably there were certain rules for tribal fights. For example certain body part were off limits as targets. Also it was not a fight to death, as fights usually calmed down after first blood has been drawn. Occasionally women picked up weapons and fought their sister.
Hand-to-Hand combat
If a group fight had continued for a periods of time, tribal leaders would nominated a local hero to defend the honour of the tribe. The warriors discarded every weapon except a shield and single combat weapon which could be a flintstone knife or a nulla nulla club.
