Good comparison G O, bikies are pretty tribal and violent and common in plenty of countries. Maybe the Bandido's will bring Olympic Dam to a halt?

I'm not suggesting that it's a crime free zone, but it is a unified country without the tribally controlled areas that are typical of Libya or Syria and lots of other Middle East and African countries.

So the prospect of the rig being stopped by marauding tribesmen, who consider that they own the territory it's travelling through seems very low and no more of a consideration in Tunisia than most parts of the world. Your original post about tribesman seemed to imply that you foresaw a problem of that type.
Admittedly it had no detail to it, so it was hard to know what you actually meant.
