Culling crocs a bone of contention in Kakadu National Park A ROW has broken out among Aborigines over whether to cull crocodiles in Kakadu National Park, in the wake of an attack that is believed to have claimed the life of a 12-year-old boy and injured a 15-year-old boy. Representatives of one of the area's most powerful Aboriginal traditional owner groups last night said it was "high time" a cull was carried out, declaring the issue a "bone of contention" between them and the commonwealth park administrators, Parks Australia.
