You are correct, the rules do apply until they come into conflict with a operational necessity. Then defenses' own risk management framework comes into play. Otherwise you would be breaking the OH&S rules by having someone fire a bullet at you. That would make the core business of war-fighting very difficult!
Those structures to contain RAAF aircraft have many different uses; keep the sun of while doing hours of maintenance, containing a weapon blast should it go off accidentally, amongst others.
