Australia introduces illegal gun amnesty after Islamist-inspired attacks

Australian Justice Minister Michael Keenan said that from July 1, locals can hand-in illegal firearms to authorities without prosecution.

"We are living in a time when our national security environment has deteriorated. Unfortunately, we have seen, through terror attacks in Australia that illegal guns have been used," said Keenan.

Australia's has some of the world's toughest gun control laws, introduced after the country's worst mass murder, when a gunman killed 35 people at Port Arthur in the island state of Tasmania in 1996.

Australia, which has banned all semi-automatic rifles and all semi-automatic and pump-action shotguns, and as a restrictive system of licensing and ownership controls, has had no mass shootings since 1996. It is held up by many abroad as an example of the need for tighter gun controls in the United States.

But a 2016 report estimated there were 260,000 illegal firearms in Australia, some of which have been used by radicalised locals to commit attacks.

In Australia's most deadly incident inspired by the Islamic State group, a gunman used an illegal firearm in a 2014 Sydney cafe siege in which three people, including the hostage taker, were killed.
