In play —
The Port Arthur massacre was a mass shooting that occurred on 28 April 1996 at Port Arthur, a tourist town in the Australian island of Tasmania. 35 were killed and 23 were wounded. The murdered were aged 3 to 72. The single shooter used a Colt AR-15 in .223 / 5.56 NATO and an SLR, the L1A1 Self-Loading Rifle, in 7.62×51mm NATO.
The massacre quickly led to the 1996 Australia NFA, the National Firearms Agreement, passed only 12 days after the murders. The NFA placed tight controls on semi- and fully automatic weapons and included a gun buy-back provision.
Australia’s gun laws changed fundamentally. In two federally funded gun buybacks and voluntary surrenders and State Governments’ gun amnesties before and after the Port Arthur Massacre, more than a million firearms were collected and destroyed, possibly a third of the national stock.
A person must have a firearm license to possess or use a firearm. License holders must demonstrate a “genuine reason” (which does not include self-defense) for holding a firearm license and must not be a “prohibited person”. All firearms must be registered by serial number to the owner, who must also hold a firearms license.
A study found that there were no mass shooting deaths of five or more in Australia from 1997 through 2006, though the authors note that it is impossible to prove the agreement was the cause.
Two other shootings took place, in 2018 and 2019.
2018 Osmington shooting — The Osmington shooting was a familicide in Osmington, Western Australia, on 11 May 2018, in which Peter Miles, a 61-year-old retired high school farm manager, shot dead his wife, daughter, and four grandchildren, before calling police and then committing suicide. It was the worst shooting incident in Australia since the Port Arthur massacre of 1996.
2019 Darwin shooting — On 4 June 2019, a mass shooting occurred in Darwin, Northern Territory, Australia. The Northern Territory Police confirmed that four people were killed in the incident and another one was injured. A 45-year-old man, Benjamin Glenn Hoffmann, was arrested and subsequently convicted for murder and manslaughter.
