As mentioned earlier, the first thing I've done is engage my next door neighbor to quote on an alarm / monitoring system. A bollard will also be placed inside, directly behind the roller door. I'm not going to divulge info regarding the security system, but i can be there onsite from my house within 4 minutes during peak hour. There is also a massive wrought iron fence that auto closes at a certain hour and can only be opened via remote control. There's only one way in / out.
WORST case scenario is a ram raid and the thieves loading one machine before I get there. I can "look after" myself
The location and existing security was the governing factor in selecting this building. Research on the building indicates it is very well constructed (as Jeff pointed out), and there will be a "blue chip" company building the factory which is located on the street.
I DO appreciate ALL the ideas and comments put forward. The kind words of encouragement are also greatly appreciated. Things will change in Melbourne regarding the (lack of) social pinball scene and interstate members will be more than welcome.
Certainly - if anyone is in the racking and pallet lifting industry - feel free to contact me, as I need quotes on storage etc !
