After a few enquiries it appears that the customs have absolutely no right to do a cavity search. It is not the medical personel presence that is required but the fact that a cavity search can only be carried out by qualified medical personel.
I suggest that it is our responsiblity to advise our crews of this during briefings and to support them where required.
This country still has laws that even the local customs are required to observe.
