GBIF data record 6 Gahnia species in the region, but this appears the best match to other posts on iNat.
This is the 3rd time I have run across this cryptic little sedge in escarpment bogs (this one being at 920m elevation). The first time I sent a specimen to Sydney RBG who ID'd it as O. distichus. It appears to be uncommon, although hard to spot among taller sedges.
Growing in a small farm dam with Eleocharis sphacelata. I thought it might be Schoenoplectus pungens, whatever that is called now, although the culms were more yellow-green than blue-green. Didn't have a camera with me, so no in situ photos. It was forming small tussocks about 70cm high around the dam margins.

Not sure between M. gunnii and M. nuda, but I think the tussocks were large enough that it has to be gunnii (nuda leaves to 40cm long in NSW Flora, these would have been closer to 100cm). Some inflorescences straight, some flexuous. Nuts shiny, smooth, almost black, no hypogynous bristles. In drier grassy areas of a montane bog at about 900m elevation.
Forming large diffuse tussocks in montane bog at c. 740m elevation.
In a damp depression in a dune swale at the mouth of Wallagoot Lake. Tiny rhizomatous sedge was the most abundant species in the wettest bit, with Hydrocotyle bonariensis and Cyperus polystachyos.
On dunes and sandy headlands south from Kioloa although there is a record for Burrill Lake dunes
