So Aussies just sit and take this shit? Why?
I live in in Thunder Bay, which is an amalgamation of two cities - Port Arthur and Fort William. The two were amalgamated in 1970.
The plebiscite choices for the name of the city were "Lakehead", "The Lakehead" and "Thunder Bay".
Only in Thunder Bay does 60% of the vote being split between Lakehead and The Lakehead, end up with the name Thunder Bay winning, LOL. I think the Australian model is a weighted system to prevent stuff like that from happening.
But I digress [what else is new?

].
TO YOUR QUESTION:
Australia has a Port Arthur too - and in 1996, there was a mass shooting there that left 23 or 27 people dead [something like that].
Australians, being complete morons, decided to give up all their guns, LOLOLOL. What could possibly go wrong?
Dumb fucks. I'm glad to see this happening to Australia. Indeed - I'M FUCKING LOVING IT.
What the hell are they going to do now? Hey - they "trusted" their government. And this is the consequence.
I liked the movie "Crocodile Dundee" though. I only watched it for the first time, earlier this month.

"That's not a knoife", LOL.
