Laws that have a logical reason, for safety and security I have no trouble with, licencing, storage, registration and transporting.
The ones that are just illogical knee-jerkery sh!t me to tears.
In NSW, you have to have a permit, as for a firearm, to own a totally inert replica. You have to supply a genuine reason, as for a firearm. You have to store it the same way as the category of firearm it replicates, all for a harmless, realistic looking TOY.
We all know the unbridled f*ckery surrounding the acquisition and storage of the inert metal tubes known as suppressors.
The fact, mentioned previously in this thread, that there is a category difference for repeating and self-loading firearms.
The replica nonsense also applies to knives, something of which I am also fond.
I am allowed, for example to import through the post a Cold Steel Magnum Tanto, with a 12 inch blade of surgically sharp San Mai steel, an item that to quote Squint Eastwood, "will take your head clean off". I pay the manufacturer in the USA and 10 days later the posty delivers it.
Several years ago I purchased two replica knives from Cold Steel, made from Grivory glass reinforced plastic. These are used for training purposes and can cut cheese but little else.
Instead of my knives turning up, I received a letter from customs telling me they had been confiscated as a prohibited item, as non-metallic knives were illegal to import.
To get them released to me I had to apply to the Police Minister, giving a detailed description, including picture and measurements, detail why I wanted them and how they would be stored.
When I eventually received a permission letter from this minister, I had to include that with another application form, detailing everything as before to the Customs Minister and wait several more weeks before being granted his permission. I then had to include both permissions with a third application to Customs themselves to finally get my two plastic knives.
6 months and many dollars worth of postage later they finally arrived, accompanied by a letter threatening me with jail and 6 figure fines if I was to attempt to do this again without prior permission.
We have self-serving chair polishers making up these bullsh!t regulations for no better reason than to try to justify their place at the trough.
