Many Indigenous communities also have a very complex [[Australian Aboriginal kinship|kinship]] structure and in some places strict rules about marriage. In traditional societies, men are required to marry women of a specific [[Moiety (kinship)|moiety]]. The system is still alive in many Central Australian communities. To enable men and women to find suitable partners, many groups would come together for annual gatherings (commonly known as [[corroboree]]s) at which goods were traded, news exchanged, and marriages arranged amid appropriate ceremonies. This practice both reinforced clan relationships and prevented [[inbreeding]] in a society based on small semi-nomadic groups.
