You will need this permit if you intend to purchase / acquire a firearm. A firearm cannot be legally sold, bought or acquired unless you (the purchaser) have a valid permit to acquire and the transaction takes place through a licensed firearms dealer.
You must already hold a relevant licence or permit authorising the use or possession of the firearm. This is a separate (additional) permit that is required for each firearm that you intend to acquire.
The purchase of any firearms must be conducted by a licensed NSW firearms dealer. If there is no licensed firearms dealer within 100km of the residential address of both the buyer and seller, the transaction may be witnessed by an authorised police officer.
The purchase of an imitation firearm does not require a permit to acquire firearms where you have a licence to possess or use an imitation firearm.
