The common definition of a 'mass shooting' in 1996 was five or more victims killed by gunshot in proximate events in a civilian setting, not including any perpetrator(s) killed by their own hand or otherwise. This excludes most of Australia's more common firearm-related spousal and family violence killings.
In September 2014, a farmer in Lockhart, New South Wales, shot dead his family of four, then himself. In May 2018, at Osmington, Western Australia, another farmer shot dead six family members before taking his own life. In recent years, a lower threshold has been widely adopted, with 'mass shooting' coming to mean four or more victims shot dead, not including the perpetrator.
