My understanding of Australian guns law is that unless you are a farmer, professional shooter (such as professional competition shooter or professional pest hunter) or collector you are only allowed paintballs markers, air guns and non-semi-automatic rimfire/centerfire rifles and shotguns (pump action shotguns are subject to same restrictions as semi-auto shotguns). Pistols can only be owned by target shooters and the caliber is restricted in most cases to .38 (9mm).

Things just got worse for our Australian gun owning brethren:

The Federal Government will change import regulations to tighten controls on firearms that have a “military-style appearance”.

…

Mr Debus said that there was “absolutely no reason” for anyone to own a shotgun that looked like a semi-automatic rifle.

Now any rifle, shotgun or even paintball marker looks like a semi-automatic is will be destroyed by customs. This will limit the import of pump-action rifles into the country. Apparently they have been importing the Romanian pump-action AK pattered PAR-3/PAR-1 rifle.

From the above article. Looks like a
AU legal PAR-3 or PAR-1 (top).

I am sure they will ban the pump action Remington 7600 rifle pistol grip and M4 style stock as well. I believe the 7600 is popular in Australia. The politicians must have forgotten to ban pump action rifles.
