A waddy, nulla nulla or hunting stick is an Australian Aboriginal war club. The former name comes from the Dharuk Aborigines of Port Jackson, Sydney.
A waddy is a heavy club constructed of carved timber. Waddies have been used in hand to hand combat, and were capable of splitting a shield, and killing or stunning prey. In addition to this they could be employed as a projectile as well as used to make fire and make ochre. They found further use in punishing those who broke Aboriginal law.
They were made by both men and women and could be painted or left unpainted. Their construction varied from tribe to tribe, but they were generally about one metre in length and sometimes had a stone head attached with bees wax and string. They were made from where a branch met the tree, or from a young tree pulled up with its roots from the ground.
Waddy has also been spelled as wadi, wady, and waddie. The spelling stabilised around the mid-nineteenth century, partly to help distinguish it from the Arabic word wadi, a dry water course.
