I've got both NTs and QLDs plus some of unknown origin(orange phase) it all depends on where they come from...NT and QLD are big places, inland QLDs tend to be dark brown with lighter brown banding....which is what alot of people talk about when they say QLD form.
Like with alot of reptiles in captivity origin info means next to nothing as its mostly wrong or made up.
IMO my orange BHPs are my favs...but i don't really care they are all awsome animals.
