I had originally identified this as variety ornata - my picture is close to identical to the said ornata in the books, but that Caladenia is found in Western Victoria. Mount Samaria is in the north east, south of Benalla. I have been in contact with Gary Backhouse, co-author of our favourite orchid book and he believes it is just a very colourful C. carnea. Whatever, it is a splendid orchid.
