Interesting suggestion. Pauridium (was once Hypoxis) is in Hypoxidaceae so is closer to Hypoxis (Tricoryne as suggested by AI is in different family). Looking at this again, and checking off against VICFlora and PlantNet opens a can of worms, hard to settle:
Stamens of P glabella and P. vaginatus are alternating long and short (this trait not evident in these photos).
Tricoryne doesn't fit very well: these plants were quite short (less than 10 cm), much shorter than usually given for T. elatior; the stigma is obvious (not "minute" as for Tricoryne); and the filaments don't appear to be hairy. I can't tell with confidence if anthers are basifixed (Pauridia, Hypoxis) or dorsifixed (Tricoryne).
Stamens in Pauridia are usually in 2 whorls (can't see two whorls).
In this TSR, habitat for this plant was slope of a small valley, on saturated soil: recently burnt. Plants were part of a short dense re-growth carpet, and leaves very hidden by other plants.

Not sure how I missed this sighting, but I agree with Ciaran here, anthers look wrong for either subsp. of Hypoxis. The AI is definitely wrong, it's not Tricoryne either based on the anthers.
