A paintball gun (legally referred to as a “paintball maker”) is a device that can propel, or is designed to propel, a paintball by means of any gas or mixture of gases, including air (but not including a gas or mixture of gases generated by an explosive) and is operated or designed for operation by means of a trigger or similar device.
In NSW, paintball guns are regulated differently from firearms because the law recognises that paintball guns can be used safely in a controlled environment, such as an authorised paintball venue for sporting or recreational purposes. There are no special laws that treat gel blasters differently from firearms.
