bertie 1233,
I reckon you are on the right track.
Perhaps we should call the NT EPA and get them involved. After all, it is only about 700km south of Darwin and goannas might be endangered; especially if they climb the Christmas Tree.
In addition, the location is in the wilderness so the Wilderness Society and Bob Brown should be warned so they can seek an injunction to stop this foreign owned Coy from exploiting our pristine desert...
