Victorians have surrendered more than 9000 firearms during the second nationwide gun amnesty since the Port Arthur massacre more than two decades ago.
Items surrendered during the three-month amnesty include 9175 guns, 151 weapons and 103 firearm parts, more than doubling Victoria Police's preliminary estimate of 4000.
"We always expected the final number of items surrendered during the amnesty to rise, however, in the last three weeks of September we saw more than 1050 firearms surrendered each week," Superintendent Paul Millett said on Wednesday.
More than 98 per cent of firearms surrendered during the amnesty were not registered, Supt Millett said.
A number of rare and historically significant firearms were also handed in and have since found homes in museums across the country.
The last national amnesty was called in 1996 by former prime minister John Howard after the Port Arthur massacre in which 35 people were killed, and was accompanied by a gun buyback scheme.
