Not sure if I have enough detail to identify the species, or if the location is enough? Any tips on what I should be looking for or photographing with these plants would be appreciated.

There are only two possibilities - Xanthorrhoea glauca subsp. angustifolia and Xanthorrhoea australis (unlikely) presuming this is a tree type Xanthorrhoea. The easiest seen difference between these two species is the length of the flower stalk below the flower spike - up to 0.5 m long in australis, and 0.5-1.4 m long in glauca subsp. angustifolia. Glauca subsp. angustifolia leaves are always glaucous (bluey green with a whitish bloom) while those of australis are usually green, occasionally glaucous.

I have now looked at ALA and NSW Bionet Atlas. Both say that Xanthorrhoea australis is the common species at Burrinjuck. There are only a few records of glauca, dating from the 1950s.
