Here’s an example of what we commonly get. Where are they lying? I wouldn’t doubt that they are, but I’m interested.

"placing a complete ban on semi-automatic rifles and shotguns."
That's not true. In some states, it's almost true, in others it is less so (the NFA is far weaker than this article suggests).
Take a look at this page from Cleaver Firearms, a gun store in Queensland - https://www.cleaverfirearms.com/Products.aspx?Category=Category%20C%20and%20D&Brand=44
I haven't quite taken the page at random, but close to it.
Semi-automatic rifles openly for sale. So - the 'complete ban' in the article is just not true.
Now, you'll note these are low calibre - because it becomes much harder to get such weapons in higher calibres. And they are all category D firearms, which do require a quite hard to get permit to own - I have had a Category D licence in the past, but today, I have decided I only need a Category C for my purposes and that is much easier, and I still own a semi-automatic rifle on that licence (same type of rifle I carried on occasion when I was in the Australian Defence Force, actually).
