All Australian states and territories ban 3D guns, but only some jurisdictions like New South Wales, Western Australia and Tasmania make it an offence to possess blueprints.
Experts are calling for retailers to play a greater role in choking the supply of 3D-printed guns in the wake of the Bondi shooting
Gun control groups are pushing for more laws that ban the importation of 3D printers if they do not have pre-installed software blocking firearm parts from being manufactured
Retailers offering 3D printers or 3D printing services would report customers suspected of building 3D-printed guns to the authorities under fresh calls for corporate Australia to play a role in thwarting access to the deadly weapons

Why would it not make sense to rather better limit access to ammunition and gunpowder? There must be ways to cobble together parts into a gun-like object through other means than 3D printing, but nothing will fire without ammunition, and that seems a bit more difficult for someone to pull of themselves? Or is that incorrect?
It’s Australia. Our lawmakers just throw together some crap that makes no sense and doesn’t achieve what it sets out to do, pat themselves on the back for their ‘courage’, and call it a day. Thankfully though this is isn’t becoming law (yet)
