Yeah, about that Australian Model of gun control,

not working so well. 
Previously unseen police statistics show that the number of pistol-related offences doubled in Victoria and rose by 300 per cent in New South Wales. At least two other states also saw a massive jump in firearms-related offences during the same period.
Hmmm, wonder why they were 'previously unseen'.
The statistics detail the types of firearms offences police have pursued in the courts in the past decade and show some concerning findings, including a massive 83 per cent increase in firearms offences in NSW between 2005/06 and 2014/15, and an even bigger jump in Victoria over the same period.

So, bad guys are still getting guns despite honest citizens being screwed by the laws.  Sound familiar?

Here's something else that'll sound familiar:
Samantha Lee, an advocate for tighter firearms laws at Gun Control Australia, said the laws regulating the sale of ammunition in Tasmania and Victoria were weak.

“There is very little regulation of ammunition purchase,” she said. “In most jurisdictions you can purchase ammunition because you have a firearm licence and there is no restriction on the type you can purchase – so if you own a rifle you can still purchase ammunition for a handgun.”
So 'very little regulation' means
"You can't buy it without a firearms license, and if you're caught with a round and you don't have said license you'll go to jail, but IT'S NOT ENOUGH!"
And it will never be enough for these people until it's all banned, and only the .gov and the crooks have guns.

(Yes, I know, the article's a couple of years old; the points still hold)
