Thanks Lionrock. They are found in southern parts of Australia. I live about an hours drive NE of Melbourne, and my property backs onto a reserve of around 30 acres, which has these orchids. There's roughly 50+ types of orchids, green hoods, sun orchids, wax lips, etc in the reserve, but usually in small groups. The two above were in a group of 10-12 in the space of a small room, if that helps. At the moment, I'm trying to track down a Bearded Orchid, which appears as a single plant, in the space of an acre or so (well, there's usually about 5-6 in that area). Not easy to find, but fun when you do
