I think this is O hamatus. O calceolus occurs at Bungonia, however that is supposed to be a redder plant with a broader labellum. Admittedly, they do look nearly identical.

@MattM I took a few more sightings of other populations of oligochaetochilus sp. in Bungonia NP so I'll upload them now. Perhaps they will have clearer features to assist in ID.

An interesting development I must say, Ned. This sighting is within the heart of the O.calceolus stronghold so we had both assumed that all the Oligochaetochilus sp would be b O.calceolus. They were certainly widespread, growing primarily on sandstone, but also on the flat limestone near riverbanks, all of the plants appeared to be fairly similar. We have a further 9 records of O.sp between us so hopefully one of them is the Bungonia rustyhood :).

I would like to see what @TobiasHayashi has to say. I believe he might have some experience with the species.

I've actually never seen calceolus in flower - not sure how, just never got out there at the right time I suppose. Just had a flick through the various sightings uploaded, and gut feeling is they are all O calceolus. Flowers do seem pretty red and labellum variably broad or not as broad, but they don't seem to have the same real curved and stripey character of hamatus. Will look at this again later.
I can't recall having heard that O hamatus grows at Bungonia, although of course that's not a good reason to confirm its not.

Have looked through these photos again am of the opinion they are all calceolus. They are all redder, more uniform with less striping than hamatus, and with lateral sepals less hooked forwards and labellum relatively broader (although these vary a bit). And, as you say, core calceolus country
