You're a little confused, perhaps it's our fault for leaving out an important piece of the puzzle.
There is no individual licencing for importing replica firearms. The only licence available for importing replica firearms is for businesses, hence the Business Firearms Licence.
You could have a PAL for prohibited firearms, and you still wouldn't be able to import replica firearms for your own use.
