Not sure how this Sighting is coming up on the Alerts as Lepidosperma when Moderator has selected Lomandra.
First and second photos seem to have inflorescence structures at the base

My accidental clicking suggested ID, then rapidly deleted that suggested ID and messaged the author Martin Predavec.
Too late for the single email notification .
Humbly I actually have 35+ years of skills and extensive experiences (not authority figure super-human perfect. I reject fallacies including: argumentum ad verecundiam et auctoritate.).

Great !
Thank you !

First impressions:

Fertile material remains of two fruiting structures shown (initially inflorescences then infructescences):
[Edit:] two female fruiting structures shown:
• short compared to the foliage and compared to typical Lomandra longifolia and
• has the spines (spinose bracts) of the group of several species which includes Lomandra longifolia, Lomandra hystrix, Lomandra spicata, Lomandra confertiflora, Lomandra fluviatilis, etc. .

The lower parts of the foliage shown in these two added ground level photographs:
• bases of the leaves' have multiple ribs or veins on their under-sides and
• on the upper sides they appear to have a mid-vein broader and flatter than merely a line.

The leaves' upper sides' pronounced concave (cross section shape), I am noticing now.

To re-check the up to date systematics of this group of Lomandra species, in that context investigate these photographs further, and then get back to you here.

In your first hand observations please, do the leaves' tips have any teeth ?
(Not so easy to focus photograph the leaves' tips – the reason i didn't ask fo that too).
(Perhaps multiple leaves' tips layed flat on a contrasting surface and macro-photographed if possible and not too difficult)
Your description of first hand observation may provide better information than photographs of the leaves' tips, anyway.

I see two leaves' tips in low–resolution–detail in the first photograph.

Now i am noticing in these two added close-up photographs:
Less obvious, weathered old taller fertile material remains – of the taller male inflorescences? (inflorescences meaning: compound flowering structures)
Rather than, the obvious to see old remains of the fruiting female infructesences .
(infructesences meaning: compound fruiting structures) .

Also, Martin Predavec and any of you reading here,
like going deeper into the many Lomandra species in NSW and Qld,
you may enjoy the 'light reading' of awesome Jian Wang ter, Qld Herbarium Brisbane based botanist:
https://www.researchgate.net/profile/Jian-Wang-143

He, obviously, keeps working hard, doing high quality systematic science,
including much field work and publishing many new species descriptions,
to revise all the species concepts, their taxonomy and names (nomenclature) of the whole Lomandra genus across Au, –or at least across eastern Au so far.

Thank you @JasonPStewartNMsnc2016 ! In answer to your question - no teeth on the tips. I'll have a look through some of Jian Wang's work as suggested. Many thanks - Martin

Thank you Michael Predavec.
No teeth on the leaves' tips, rules out (disproves) the identification of _Lomandra longifolia_ in the strict sense.
While these plants obviously identify in the group of many different spp. related to, _Lomandra longifolia_ in the strict sense.

For the short term of days–weeks until my investigation of Lomandra spp. in this group, gets done, as time permits,
I have provisionally confirmed this to _Lomandra_ sp. . (Deliberately ignoring 'wildthings' ignoring all our work so far done here.)
