Looks like _Lomandra filiformis_ in my first looks. Botanically keying this out now in the Flora of NSW online PlantNet spp. key and the subspecies key – as the best way of re-checking my knowledge.
Please estimate how wide these leaves are in mm ? eg. 0.5 to 1 mm, 2 mm, 2.5 mm, 3 mm or 4 mm or more . An estimate from your memory will do (– no need to re-visit this plant for measuring sample leaves) .
Oh thanks for the measurement additional photograph . Yeah about 1.5 mm wide as is (more or less inrolled) and if flattened i estimate 2–3 mm wide. I'll have more of a go of botanically keying out to the subspecies of _Lomandra filiformis_ .
Yeah, seems _Lomandra filiformis_ subsp. _filiformis_; but from attempting to work together, this sighting including your focussed and good photographs (or any photographs per se) and the Flora of NSW online PlantNet key to the subspecies; hard to confirm subspecies (as regularly occurs in systematic efforts to identify subspecies of _Lomandra filiformis_ from photographs per se) .
