Anyway, I went back yesterday to check their progress.
The plants I had originally found were not properly open
(but they were recognisable as being this species).

Fortunately I found another group of these lovely flowers, fully open.

These plants are growing in deep sandy soil on top of Cambewarra Mountain. They are growing in a semi-open heathland shrubbery, not in the rainforest one sees on that same hill, from the main road between Kangaroo Valley and Nowra. Obviously it is a very high rainfall area, but the sandstone provides excellent drainage.
Here is a shot of one of the flower spikes.

Cambewarra is an interesting location, in that it is nearly at the same altitude as Kangaloon, but its proximity to the warm coastal plain seems to bring forward the flowering time, relative to the same species at Kangaloon (where they are yet to flower). So altitude (and proximity to the coast) appear to give a considerable delay to flowering time, in Springtime flowering Orchids.
