Each state and territory has its own laws and regulations in regard to offensive weapons. An offensive weapon is defined in the Crimes Amendment (Offensive Weapons) Act 1999 NSW as being:
A dangerous weapon is anything that is made or adapted for offensive purposes. Anything that in the circumstances is used, intended for use or threatened to be used for offensive purposes, whether or not it is ordinarily used for offensive purposes or is capable of causing harm.
This also includes anything that is used or intended to be used for self defence. A weapon becomes an offensive weapon either:
By obviously being something that is capable of causing injury if used and is being carried in public but is not on the Prohibited Weapons Schedule, such as a stick, baseball bat, iron bar, 4×2 piece of wood and carried without reasonable excuse.
By the admission of the person in possession that the object is being carried for self defence purposes.
So if you are walking along the street carrying a stick and you are asked by police “what’s that for” and you answer “to defend myself” you are in possession of an offensive weapon. ..... "
