This looks to me like the other one: smaller flower, smaller lateral sepals and shorter labellum...which makes it a little complicated. I suspect it is what David Jones refers to as Bunochilus aff. montanus in the ACT orchid guide, rather than 'true' montanus. I'll confirm it as montanus, as all the similar records in the ACT on CNM are included in montanus, although it is probably aff/ montanus which might be the same thing the Victorians call Pterostylis loganii.
