Australia confiscated many weapons just a few years ago after that crazy shot some tourists in Tasmania. Aussies are pretty much disarmed.
No, we're not.
Australia's state governments with the support of the Federal government did impose stricter licencing procedures on the ownership of all but basic firearms following the Port Arthur massacre. But Australians who were willing to get the necessary new licences, typically had few problems keeping their firearms at that time. In a collossal waste of money, the government purchased many unused but legal firearms from gun owners who chose to voluntarily surrender weapons in exchange for cash. A small number of people, often those with old criminal convictions which did not prevent them having basic firearms licences but did prevent them having higher level licences, were forced to surrender their more powerful weapons. Another small number had to surrender weapons which were not cleared under the new laws.
But many more Australians kept their firearms. And many more have purchased them in recent years. There are millions of legally held firearms in private hands in Australia. We're not disarmed.
The post-Port Arthur gun laws were wrongheaded and largely pointless. But they really didn't do that much damage, they just added a new layer of bureaucracy to an already top heavy administration.
