Keep it hidden from window view. Do not tell ANYONE where it is and what is in it apart from your trusted insurance company of course

Tie it with rebar and epoxy into a column or beam and put a sturdy steel brace on it that blocks opening the door without the key that opens the padlock. All easily made good when removed and you move on. Couple of kilos extra baggage at most. Cheap and noisy portable alarms also easily available. All said, if they want it there is always a way.

Sledgehammer attack is out, as I've installed it backing onto an inaccessable wall, not one that's directly on the outside.
All the doomy talk about wall-removal is like cheap posting, noise, noise and more noise is a thief's worst enemy.
I will tell you now something about where I am.
The thieves here are nearly ALL opportunists and from people I've spoken with the only tools they use are what they find in the house or garden to get access, so I'm not losing any sleep on this.
I think a lot of you need to take off the 'professional thief' rambling and leave that back in the west where you get them.
Here in Thailand they isn't a real 'pro' class of thieves like back home.
Crazy, you've confused me on the rebar, brace and wall buzz mate.
You got any pictures to demonstrate what you are on about?
