Australia had a mass shooting in 1996 and pretty strict gun control came in. Now it’s only really sport shooters (who are a pretty responsible bunch from my experience), rural property owners with a good reason (pest control largely), certain occupations like specific security (cash transport for instance), cops and military that have guns. And criminals.
We still get the odd shooting but they’re pretty rare and to my understanding, almost never done by legal owners.
I’m not sure what things were like back in 1996 but I don’t believe we really have the gun culture so there’s not much opposition to gun control by the majority.
I believe it refers to a similar concept in the car modding scene.
