I could have been reading too much David Thorne, but doesn't all widlife in Australia want to kill you? Like, actively out for your blood? Possibly not so much in the urban areas, but I'd have thought there would be some consideration for "I live in the middle of nowhere and everything within 50 miles is hunting me."
Well, sorta.
You need a valid reason to have a weapon, and you have to prove that a lesser category weapon wouldn't be better.
Living in a rural or farming environment is a reason for a Category A weapon, which includes rimfire rifles (not semi-automatic) and shotguns (not semi-automatic or pump action). In some states this might exclude lever or bolt action shotguns, not sure.
So, you live on a farm in the middle of nowhere, you are allowed a double barrel shotgun, say, provided you lock it away properly, have little or no criminal record etc. Or one of those combination rifle/shotgun survival guns.
A Category B weapon would be a not semi-automatic centrefire rifle. Those are harder to get, but not by much, I believe.
...
"You can" get a semi-automatic centrefire rifle, such as an AR-15, if your job is to hunt big game. Which it won't be so you can't.
Automatic weapons are flat out banned.
