I need a photo, or field notes, regarding the stem, before I can confirm this sighting. All the local sightings of Thysanotus this spring so far have been of the twining Thysanotus patersonii.
This isn't a contemporary photo. It is from 24 November 2010. It was an upright stem, from memory about 30cm high. I have a photo of Thysanotus partersonii from that same spring of 2010, taken on September 14, which I will upload, which was prostrate.
