latifolia?

The flower spikes are over twice the length of the scapes, which is consistent in the population, therefore likely X. australis or X. glauca. If X. resinosa, I would expect to see the scape and spike length roughly even. The leaves/crowns are grey-green/glaucous coloured not green as would be expected in X. latifolia. The leaves also do not appear broad and have little flexion, which is always evident in X. latifolia on account of the very shallow and broad leaf cross-section shape.
If the area of this sighting were included, this would aid with a more accurate ID.

This will be X.australis then I think, plants are from lake Munmorah in the Sydney region

There are no records of X. australis north of Sydney. Looking at the habitat, it is not typical of X. glauca, this could then be a hybrid between X. glauca and X. fulva, which are known to occur from Newcastle to Byron Bay, the progeny can resemble X. resinosa, the crown shape and very straight leaves are highly suggestive of this.
