There is a push for better (IE more relaxed) gun laws here in Oz, whether or not anything will come of it is anyone's guess.
Personally ISIS doesn't worry me, at least not directly, if they do anything it will be in the cities and I
almost never go into one.
And we are armed, or at least lot of people are, not with AR/AKs I admit but we can still own some pretty good gear, for example this Aussie-made toy is about to be released.
Yeah yeah I know, it' not semi auto, but remember in Oz nobody else has semi-autos either (well I'm sure some people do but not as a rule). So like the two guys running from a lion, I only have to run faster than the other bloke, not the lion. By owning even a few decent bolt/lever/pump/revolver-action rifles you are well ahead of the pack.
So despite the fact that I can't own an AR etc, I still feel pretty secure against most threats likely to be encountered in country Oz.
