Blue Lady Orchid (Thelymitra crinita) near Waroona, Western Australia. Photographed on 29 October 2008.

I had previously labelled this T. macrophylla but it was brought to my attention that it was probably T. crinita. In looking at it again, T. crinita has more rounded petals and sepals, and I have thus accepted that it is truly T. crinita rather than T. macrophylla. Thanks Jean (jeans_Photos) for the suggestion.
