Nature Australia certainly does include some errors in the answers to their quizzes (they have admitted to me). However in this case I would agree that the answer is five, in that the likely intent of the question was to be broad and to view the word crows in the generic sense. Ravens are crows in that they are members of the same genus. Actually questions like that are often ambiguous as maybe the level being considered is family or order. The question of "How many species of parrots are native to Australia?" should include Rosellas as they are parrots but we give them another name as a subset of parrots.
