Why not here? Australia's Gun Ban Has Worked Big Time

25. That is not true.

The sale, possession, and use of firearms are regulated by the Australian states and territories, with cross-border trade matters addressed at the federal level. In 1996, following the Port Arthur massacre, the federal government and the states and territories agreed to a uniform approach to firearms regulation, including a ban on certain semiautomatic and self-loading rifles and shotguns, standard licensing and permit criteria, storage requirements and inspections, and greater restrictions on the sale of firearms and ammunition. Firearms license applicants would be required to take a safety course and show a “genuine reason” for owning a firearm, which could not include self-defense. The reasons for refusing a license would include “reliable evidence of a mental or physical condition which would render the applicant unsuitable for owning, possessing or using a firearm.” A waiting period of twenty-eight days would apply to the issuing of both firearms licenses and permits to acquire each weapon.
