Not having been there, I can't add much. Best advice is have a look at Steven Debus' new book (reviewed by me in recent CBN). I suggest the Brown Falcon is among the more noisy of raptors and will call in many situations, making loud cackling, chattering and screeching calls (not like a Grey Goshawk - mellow, rather nasal, upslurred ringing whistles) - both quotes from Stephen Debus' new book, so I am not sure at the suggested quote you mention from Simpson and Day (I don't see that mentioned). As to whether anyone has sighted any falcons around the ANBG recently, that doesn't identify what you found. There are many differences in colour and shape and flight pattern between Brown Falcons and Grey Goshawks (both are possibilities). Unless you only saw it front side, I think you should be able to know if the bird was basically grey or brown on top, but you are not going to convince a RP that this could be a Grey Falcon on this.........

Hi Rob, I wouldn't describe the Brown Falcon as particularly silent, I often pick them up in flight due to their loud and distinctive call. Grey Goshawk also has quite a different distinctive call (which is deceptively songbird-like), so perhaps listening to some calls will help you nail down an ID? I don't know of any call recordings of Grey Falcons but they have been silent on the few occasions I've seen them including while hunting.
