For all those other Top End images that don't really fit into my other categories, including:

Corroboree Park Tavern: Army vehicles, marines, captive Buffalo and Crocs on display
Big things: Boxing Crocodile at Humpty Doo and Jumping Croc at Adelaide River
Road signs: Arnhem Highway Jabiru Darwin, We like our lizards frilled NOT grilled (bushfires), Warning Beware of crocodiles
Road trains: huge trucks, very common sight in the Top End, some quite large with several trailers
