Obtaining a gun license and going shooting isn't all that difficult in Australia, license will be 100% approved if you can come up with any somewhat plausible reason "my friend has a farm with a feral pig problem", unless you're in a "Outlaw Motorcycle Gang" (and if you are, then just lie about it) or if you want an arbitrarily defined "Assault Rifle". Hunting rifles are really quite common away from the big cities.
