The Port Arthur Massacre occurred on April 28, 1996, in Tasmania, Australia, when a gunman opened fire at the historic site of Port Arthur, killing 35 people and injuring 23 others. This tragic event is one of the deadliest mass shootings in Australian history and led to significant changes in the country's gun laws. In response to the massacre, the Australian government implemented strict gun control measures, including a buyback program for firearms. These reforms aimed to reduce gun violence and improve public safety, marking a pivotal moment in Australia's approach to gun legislation and community safety.
