Theft of legal guns is now the single biggest source of new guns on the black market in Australia, yet public information on the topic is scarce. This report compiles new data from state law enforcement agencies and other sources to find that over 9,000 firearms have been stolen since the start of 2020. At least 44,600 have been stolen over the past 20 years – one every four hours. Police recover only around a quarter of guns taken.
