Thank you June Niejalke (JuneN) & Frank Whitlock for confirming and Robert Lawrence for helping with the id of this species for us

General Species Information:
Found in the Flinders Ranges and possibly elsewhere
We found a patch of 6 plants. There is a VERY similar orchid, in overlapping areas, called C. viriosa.
To differentiate them June said "C viriosa usually grows in a gully, slopes of hills or moister areas but C campestris is a plains orchid thus called the Plains Orchid. The height of the plant is the most useful, a plant that grows up to 50cm can be short but a plant that grows up to 20cms does not grow to 50cm, so is more reliable for ID. So, it is best to look for the tallest plants in the area. Even in a poor season C. viriosa is still quite tall. If they don't get enough moisture they don't flower."
