Poorly handled regulatory panic
The customs regulation was passed on 1 July with little notice or publicity. My job requires me to import/export networking goods and none of the newsletters from customs agents mentioned this new regulation -- and these are newsletters which mention events which may delay a shipment by a few hours.
So it's not surprising that shipments arrived in Australia without the correct documentation during July and August.
Related to the spate of laser illuminations of aircraft, the NSW state government passed a law to make laser pointers a weapon. This was remarkably poorly handled: not until well after the law came into effect could I get simple answers to questions like "will telecommunications company staff require weapons licenses to use visual fault indicators" (basically a big laser pointer shone down fiber) and "do handheld lasers need to be stored in a weapons-grade locker as opposed to a toolbox".
The answer to both questions is yes. This implies that people who have had a nervous or mental illness in the past will no longer be able to possess a firearm, that is, to be a telecommunications company optical systems technician. Similarly, techs should avoid a bad divorce, since the tactical use of an AVO by your partner will result in you losing your license.
I think we can safely say that the NSW state government hasn't fully considered the results of its legislation.
