The situation does not appear to be so draconian in Queensland (for a change).
I searched the Qld legislative web site, and the only references to lasers were as follows:
- Control of therapeutic lasers
- Control of industrial lasers in the workplace
- Laser speed devices (speed guns)
- Rifle-mountable laser sights for rifles (Class R Weapon)
- Laser pointers at significant sporting events
So unless you decide to start observing at a major sporting event in Qld you should be okay.
Even so, I plan to check with my colleagues tomorrow - I am an IT contractor for Qld Police.
