The worst that can happen is that they will say "no permit for you".
A good friend of mine told me that, as it happened to one of his friends; so just play it carefully.
But here's the kicker. Only "Hand-held laser pointers" are illegal to import. There's no law stating that parts to make a laser pointer are illegal. Only the completed pointers.
So you can easily just as well buy a Laser module or DVD Burner diode from a laser parts site, and the other needed parts, say from Dick Smith (electrical shop), and make something that would be effectively banned from importation if it was completed.
A good cover story to make things go more smoothly is to just state that if you're importing a DVD Burner laser diode, you can easily say it is a replacement for your DVD burner. There's no illegality in that.
That's my plan anyway, to import all the parts I need, (of course, cheap); and then buy a MagLite torch from eBay so I can make that MagLite laser hack.
So yeah, all in all, remember that thing when applying for a Permit...
Also, I have already ordered a couple of parts for my pointer that Im going to be making.
