You don't need a gun licence, but you do need replica Firearms Permit.

You will need to do the following:

1. Ensure that you comply with legal safe storage requirements. This includes:
* locks on all exterior doors and windows
* lock on your Transformers collection room (or whichever room you store your gun Transformer)
* if the room is on the ground floor, you must have bars/grills fitted on all windows for that room. You are not required to do this if it is an upstairs room.
* a lockable display unit(s) for your gun Transformers. This does not need to be wall mounted (mine is a glass display unit with a padlock).

2. Complete Firearms Permit Form P634.

This is the ONLY way that you can legally import and possess replica gun Transformers in NSW. Follow this link for further information.
