Australian Gun Laws...
"State laws govern the possession and use of firearms in Australia. These laws were largely aligned under the 1996 National Agreement on Fireams. Anyone wishing to possess or use a firearm must have a Firearms Licence and be over the age of 18 with some exceptions. Owners must have secure storage for their firearms.
Before a person can buy a firearm, they 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-defence is not accepted as a reason for issuing a licence.
Each firearm in Australia must be registered to the owner by serial number. Some states allow an owner to store or borrow another person's firearm of the same category."
