This actually looks quite similar to one I photographed at Ingledene Forest at the weekend - perhaps this means that mine was A. atrovespa too? I was umming and ahhing about atrovespa vs phaeoclavia but Mark Clements hasn't gotten back to me with confirmation yet.

Tobias, I saw Mark Clements today; he says the one you photographed at Ingledene Forest was A. atrovespa.

Looking at this now I would think this is C phaeoclavia. The smaller flower size and club size (noticeable, although not very big) point towards C phaeoclavia, but perhaps more convincingly I've baited with spider orchids from 100m up the road (during my Honours research) and they've all proven to attract Lophocheilus anilitatus (the C phaeoclavia wasp pollinator). In reference to my Ingledene comments above, I would suspect that population was also C phaeoclavia, as again baiting with a few plants from there revealed they attracted the C phaeoclavia pollinator. I can't say for sure that C atrovespa doesn't grow in the Mt Tennent-Ingledene area, but I've only seen C phaeoclavia at Mt Tennent, Ingledene, and Clear Range. In fact, I only know C atrovespa from Aranda and Black Mountain and also the northern Majura Training Area where its possible that both C atrovespa and C phaeoclavia might grow together. Certainly very difficult to tell apart.
