Hi Michael M, Setaria has a single spike and does not have the small spikelets on the inflorescence, as shown in 1st photo, & the leaves are too wide.

If possible Ciaran, could you take a specimen to the ANBG for ID?

Hi Michael, I will return to the site tomorrow and see if the plant is still there, if so I am happy to take it to ANBG once I have time :).

Unfortunately, this plant has been removed in the 4 months since I uploaded this sighting, cultivated sorghum is growing nearby. Is that a possibility?? :)

Maybe not. I don't know the plant well. See the photo of the young plant on this page:

Not enough detail to tell whether E colona or E crus-galli. Need the head fully emerged and branches spreading to be sure. These species tend to merge into each other.

E crus-galli. Taking a second look, the apices of some of the spikelets are being drawn out into too much of an awn to be colona
