State laws govern the possession and use of firearms in Australia. These laws were largely aligned under the
1996 National Firearms Agreement (NFA). Anyone wishing to possess or use a firearm must have a Firearms Licence and, with some exceptions, be over the age of 18. Owners must have secure storage for their firearms.
Each firearm in Australia must be registered to the owner by serial number except firearms manufactured before 1 Jan 1901 which in some cases are exempt from a serial number or exempt from registration all together. Some states allow an owner to store or borrow another person's registered firearm of the same category.
Firearms categories
Firearms in Australia are grouped into Categories determined by the National Firearm Agreement with different levels of control. The categories are:
- Category B: Centrefire rifles (not semi-automatic), muzzleloading firearms made after 1 January 1901. Apart from a "Genuine Reason", a "Genuine Need" must be demonstrated, including why a Category A firearm would not be suitable.
- Category C: Self loading rimfire rifles holding 10 or fewer rounds and pump-action or self loading shotguns holding 5 or fewer rounds. Category C firearms are strongly restricted: only primary producers, occupational shooters, collectors and some clay target shooters can own functional Category C firearms.
- Category D: Self loading centrefire rifles, pump-action or self loading shotguns holding more than 5 rounds. Functional Category D firearms are restricted to government agencies and a few occupational shooters. Collectors may own deactivated Category D firearms.
- Category H: Handguns including air pistols and deactivated handguns. Neither SA nor WA require deactivated handguns to be regarded as handguns after deactivation. This situation[when?] was the catalyst in QLD for the deactivation and diversion of thousands of handguns to the black-market[vague] – the loophole[which?] shut since 2001) This class is available to target shooters and certain security guards where your job requires possession of a firearm. To be eligible for a Category H firearm, a target shooter must serve a probationary period of 12 months the first 6 months using club handguns, then in the remainder of the last 6 month probationary license, an application may be made, permit to acquire for one air pistol OR one rimfire pistol. A minimum number of matches yearly to retain each category of handgun and be a financial member of an approved Pistol Club. [2]
These categories – A,B,C,D and H were those determined by the NFA. The others listed here are determined by the states that have implement them at their own discretion.
Target shooters are limited to handguns of .38 or 9mm calibre or less and magazines may hold a maximum of 10 rounds. Participants in certain "approved" pistol competitions may acquire handguns up to .45", currently
Single Action Shooting and
Metallic Silhouette. IPSC shooting is approved for 9mm/.38/.357 sig, handguns that meet the IPSC rules, but larger calibres are not approved for IPSC handgun shooting contests in Australia.
[3] Category H barrels must be at least 100mm (3.94") long for revolvers, and 120mm (4.72") for semi-automatic pistols unless the pistols are clearly ISSF target pistols: magazines are restricted to 10 rounds. Handguns held as part of a collection were exempted from these limits.
Certain
Antique firearms (generally muzzle loading black powder flint lock firearms manufactured before 1 January 1901) can in some states be legally held without licences. In other states they are subject to the same requirements as modern firearms.
All single-shot muzzleloading firearms manufactured before 1 January 1901 are considered antique firearms. Four states require licences for antique percussion revolvers and cartridge repeating firearms, but in Queensland and Victoria a person may possess such a firearm without a licence, so long as the firearm is registered (percussion revolvers require a license in Victoria).
