Firstly - anyone resorting to name calling
I am writing to let you know what a bunch of wankers you are in DOTARS.
has already lost the argument, so you have now made a mute point. Congratulations.
Secondly - DOTARS is full of pulic servants whos job it is to deliver governemnt policy. ie they do not make policy, so your letter should have gone to the relevant minister.
My understanding is that all you (and any aircraft owner <5700kg non jet) have to do is demonstate that your aircraft cannot be easily stolen, so go and spend $50 on new locks.
I have had to deal with this new security stuff lately. Yes, part of it is over the top (like regulating Boulia "international" airport) , but a lot of it is common sense, which your gripe seems to be. I suggest you get a life around the same time you pick up your new locks.
