This is a Paspalidium, possibly P. distans. There are very few records of Paspalidium spp. within the ACT so I am unsure if they naturally occur within the ACT or if they have arrived by other means.

Thank you! The Setaria and this plant have similarities. The 'flowers' on this 'new' plant are smooth & with dark green markings or lines on them. They are in groups of 4 - 10 on a thin 'stalk' and 'held' close to the 'stem'. They seem to make spirals round the stem but sometimes the groups of flowers give the appearance of being separated from each other like Sporobolus creber flowers: xxxxx........xxxxxx.......xxxxx etc.
Setaria flowers are more uniformly green and are tightly clustered into the typical S. parviflora shape. There were a few S. parviflora plants in the area. I see another response has come through....

Thanks again.
By going through Grasses of the NSW Tablelands I had a short list of four species of which Paspalidium gracile is the only Paspalidium species described.
The largest plant's flower spikes radiated from the centre so the plant was circular, spread over 30 - 40 centimetres in a grazed space.
In the book, on page 55, the plant is tall but seems to be growing between boulders so it had no choice.

Paspalidium distans seems the closest match from the photos and few stems I have here.
Thank you again,

Using the PlantNet key and looking at images of various Paspalidium species I would say this is either P. distans or P. arvensum. Because the spikelets are very short (I am assuming <2.5 mm) and they arranged neatly in rows of 2 I think it is fair to call these plants Paspalidium distans.
