@MatthewFrawley . Good evening !
in the first photograph here,
please give an estimate of how wide the culm lamina is just above your finger holding it and below the shown structure of the inflorescence.
I am tentatively suggesting Lepidosperma sieberi, and require more evidences to check this, let alone to confirm this .
Confer with superficially similar Lepidosperma concavum which this does not appear to identify to .
Confer with superficially similar Lepidosperma prospectum which this does not appear to identify to .

Thank you !
One of the more recent high quality scholarly references –i recommend reading for many people here in NatureMapr–;
with the formal description of Lepidosperma prospectum;
more wonderful information;
and some taxonomic information on its superficially similar species: Lepidosperma concavum, Lepidosperma sieberi and Lepidosperma latens .

Please use your first hand experience with this plant to assist with answering this question
(from the Flora of NSW online PlantNet key to Lepidosperma spp.):
• Culms with central biconvex ridge and thin, broad, flattened margins, 5–20 mm wide – Lepidosperma gladiatum
• Culms flat, concavo-convex, or convex on 1 face and flat on the other, 3–7 [8] mm wide – 20
...
Lepidosperma concavum
...
Lepidosperma latens
...
[presumably here also when this key gets updated: Lepidosperma prospectum and Lepidosperma sieberi. ] .

Yeah okay ! LOL .
This sighting has special interest and provides an identification challenge .
Far away from home for you ? [Braidwood <–> Hyams ? ]
Perhaps a NatureMapr person with home closer to Hyams can go back to this plant?
With enough additional evidences you can gather a more specially interesting sighting and together we can gather an interesting identification and plant record .
No rush at all – these plants keep well in the wild !
Seeds have a bit more importance in identifying Lepidosperma spp. than these wonderful flowers in these photographs (with at least one unripe, green coloured, growing seed visible here. When ripe yellow–brown coloured.) .
