Kurdaitcha is a type of shaman among the Arrente people, an Aboriginal group in Central Australia.The kurdaitcha may be brought in to punish a guilty party by death.

All deaths are considered to be the result of evil spirits or spells, usually influenced by an enemy.

Often, a dying person will whisper the name of the person they think caused their death. If the identity of the guilty person is not known, a "magic man" will watch for a sign, such as an animal burrow leading from the grave showing the direction of the home of the guilty party.

This may take years but the identity is always eventually discovered. The elders of the mob that the deceased belonged to then hold a meeting to decide a suitable punishment. A Kurdaitcha may or may not be arranged to avenge them.
