The Federal Greens Leader, Christine Milne, has launched a $350 million gun buy back scheme in a bid to reduce gun crime in western Sydney.
The Greens policy is targeted at cracking down on suburban gun crime especially in places like western Sydney, where there has been a recent spike in drive-by shootings and gun related incidents.
The national scheme involves banning the importation and possession of semi-automatic handguns and a 12 month buy back scheme.
Greens Senate candidate in New South Wales Cate Faehrmann says the parliamentary budget office has costed the scheme at $350 million over the next four years.
Ms Faerhmann says it will encourage gun owners to hand in their firearms and it will lead to a severe drop in the numbers of hand guns on the streets.
Greens leader Christine Milne says if a similar scheme worked after the Port Arthur massacre, it can work in western Sydney.
She says it is a new weapon to curb gun crime on Australia's streets.
"It's the one thing to buy back the guns from the Port Arthur Massacre calibre of gun, but you have to get rid of hand guns as well," she said.
Ms Faehrmann claims efforts by the gun lobby in state politics are to blame for the proliferation of hand-guns in the community.
"We've seen the Shooters party continuing to weaken our gun laws," she said.
