I'm thinking of importing a gun-shaped phone case for my iPhone X for a YouTube project, but I'm not sure if this item would fall as a prohibited item in Australia and what customs are likely to do if they seize this item. My goal was to wirelessly pair my iPhone to my car's audio system and then pretend to shoot people with my phone in this case while running a gun app that makes realistic sounds that plays through my car. Speakers. It's a prank video fro my YouTube account.
The phone case looks like this one.

Are gun-shaped phone cases illegal?
I'm unable to find Australian laws relevant to the importation of prohibited items to Australia.
Added (1). I've just done some research and found out an imitation firearm or a product that resemles a firearm is considered a deactivated firearm according to Customs (Prohibited Imports) Regulations 1956
