My point is, as far as the law is concerned, you can't prove malicious intent based on the tags simply being for sale so I doubt there's anything the cops can do about it at this stage?
It has been put up here before.
It is an offence to have identification tags in your possession, not attached to the vehicle they belong to, unless you have good reason to do so.
Words to that effect anyway.
So basically its illegal.
Fines and possible gaol term are in the penalty units.
Couldnt be bothered searching for it again.
But its there in the legislation.
