You need a catagory C lisences, which requires you to be a primary produce (farmer). But we are only allowed 5 round limit in shotguns and a 10 round limit in bolt actions, theres no semi auto centrefires allowed unless you can prove to the commisioner that you either work for the goverment, have a large property (only allowed it for a year then they take your guns), its your job (roo shooter/pest control) or your a firearms dealer (but you cant shoot them).
