The Australian Customs regulations apply at all points of entry, nationwide. But yeah, various states do have their own regulations too.
I still reckon 5mW may be overkill. I have a little 0.5mW red keychain laser (not for AF, just as a pointer) and I can easily illuminate targets well over 50m away, especially in dim light. Seems plenty enough for AF.
I'd also not want to point my even my weak 0.5mW laser at my eye for any period of time. The eye is a pretty sensitive instrument, and any damage may not be immediately apparent.
