I look forward to what they say as when I spoke to them just then they told me that just because it has a silencer that does not make it a Prohibited Weapon and that they thought it would be an Imitation Firearm. I spoke to someone in the permits and importations area in NSW police.

They suggested that I contact Border Force as they will be the ones to classify the toy and NSW Police will simply apply that classification to the law as it stands in NSW.
