Hmm possibly Cryptostylis hunteriana based on the angle of the flower, can you check if there are in leaves at the base of the flower? If no leaves then Cryptostylis hunteriana (Leafless tongue orchid)
I can definitely see why you would think this could be C hunteriana, but the labellum would be much more tightly rolled. They are very distinctive (I've seen a bunch). This is C subulata, but still a gorgeous orchid.
