Before someone can buy a firearm, he or she must obtain a Permit To Acquire. The first permit has a mandatory 28-day delay before it is first issued. In some states (e.g., Queensland, Victoria, and New South Wales), this is waived for second and subsequent firearms of the same class. For each firearm a "Genuine Reason" must be given, relating to pest control, hunting, target shooting, or collecting. Self-defense is not accepted as a reason for issuing a license, even though it may be legal under certain circumstances to use a legally held firearm for self-defense.
