Yes, the date is correct, I took the photos on Tuesday the 22nd June. The 'Field Guide to Orchids of the Southern Tablelands of NSW including the ACT' says the flowering is between Dec-May, so I was surprised to see one flowering now. I first spotted it on the 19th June.
I think the flowers can often be quite long lasting and I have noticed they have quite a long flowering period. I saw them flowering in July last year. This sighting here is from August 2020, so I suspect the orchids forgot to read the field guide. Chiloglottis reflexa (Short-clubbed Wasp Orchid)
