the slab of meat and its unusual herb accompaniment was found by police in the northern territory .
it is believed the lamb had been shipped to a company at darwin airport , and would then be sent on to the tiwi islands 100kms to the north that the stash would have been worth $ 2000 if it had been sold , which revealed the 20g bag of marijuana .
in a statement released on thursday , police said the sender would be ` feeling a little sheepish ' after their attempt to smuggle the marijuana was sniffed out .
