That's not quite right Rob.The 1975 act only outlaws class 3B and 4 for public use.They are only used legally by researchers and scientists and the like,
who have to be trained and licenced.
Class 1 and 2, [<1mw] are fine for unlicenced public use.
Unfortunately, many of the cheap laser pointers that can be bought in Asia
are class 3B, and can be very dangerous indeed. If you have a laser pointer
that no longer has its descriptive label, or it has become illegible, you can
take it to the UWA for testing, and if it is too powerful, they will bond a neutral density filter to it.
